Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) Basis of Presentation: The accompanying unaudited consolidated financial statements for Timberland Bancorp, Inc. (“Company”) were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with instructions for Form 10-Q and, therefore, do not include all disclosures necessary for a complete presentation of consolidated financial condition, results of operations, and cash flows in conformity with GAAP. However, all adjustments which are, in the opinion of management, necessary for a fair presentation of the interim consolidated financial statements have been included. All such adjustments are of a normal recurring nature. The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2016 (“2016 Form 10-K”). The unaudited consolidated results of operations for the six months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the entire fiscal year ending September 30, 2017. (b) Principles of Consolidation: The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Timberland Bank (“Bank”), and the Bank’s wholly-owned subsidiary, Timberland Service Corporation. All significant intercompany transactions and balances have been eliminated in consolidation. (c) Operating Segment: The Company has one reportable operating segment which is defined as community banking in western Washington under the operating name, “Timberland Bank.” (d) The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. (e) Certain prior period amounts have been reclassified to conform to the March 31, 2017 presentation with no change to net income or total shareholders’ equity as previously reported.

The unrealized losses are primarily due to changes in market interest rates and spreads in the market for mortgage-related products. The fair value of these securities is expected to recover as the securities approach their maturity dates and/or as the pricing spreads narrow on mortgage-related securities. The Company has the ability and the intent to hold the investments until the market value recovers. Furthermore, as of March 31, 2017 , management does not have the intent to sell any of the securities classified as available for sale where the estimated fair value is below the recorded value and believes that it is more likely than not that the Company will not have to sell such securities before a recovery of cost or recorded value if previously written down. In accordance with GAAP, the Company bifurcates OTTI into (1) amounts related to credit losses which are recognized through earnings and (2) amounts related to all other factors which are recognized as a component of other comprehensive income (loss). To determine the component of the gross OTTI related to credit losses, the Company compared the amortized cost basis of the OTTI security to the present value of its revised expected cash flows, discounted using its pre-impairment yield. The revised expected cash flow estimates for individual securities are based primarily on an analysis of default rates, prepayment speeds and third-party analytic reports. Significant judgment by management is required in this analysis that includes, but is not limited to, assumptions regarding the collectability of principal and interest, net of related expenses, on the underlying loans. The following table presents a summary of the significant inputs utilized to measure management’s estimates of the credit loss component on OTTI securities as of March 31, 2017 and 2016: Range Weighted Minimum Maximum Average March 31, 2017 Constant prepayment rate 6.00 % 15.00 % 12.25 % Collateral default rate 0.10 % 13.61 % 5.17 % Loss severity rate 5.00 % 76.00 % 45.14 % March 31, 2016 Constant prepayment rate 6.00 % 15.00 % 9.16 % Collateral default rate 0.24 % 17.64 % 5.70 % Loss severity rate 7.00 % 77.00 % 41.97 % The following table presents the OTTI for the three and six months ended March 31, 2017 and 2016 (dollars in thousands): Three Months Ended March 31, 2017 Three Months Ended Held To Maturity Available For Sale Held To Maturity Available For Sale Total OTTI $ — $ — $ (24 ) $ — Adjustment for portion of OTTI recorded as other comprehensive income (loss) before income taxes (1) — — 1 — Net OTTI recognized in earnings (2) $ — $ — $ (23 ) $ — Six Months Ended March 31, 2017 Six Months Ended Held To Maturity Available For Sale Held To Maturity Available For Sale Total OTTI $ — $ — $ (24 ) $ — Adjustment for portion of OTTI recorded as other comprehensive income (loss) before income taxes (1) — — 1 — Net OTTI recognized in earnings (2) $ — $ — $ (23 ) $ — _________________ (1) Represents OTTI related to all other factors.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	GOODWILL Goodwill is initially recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. Goodwill is presumed to have an indefinite useful life and is analyzed annually for impairment. The Company performs an annual review during the third quarter of each fiscal year, or more frequently if indicators of potential impairment exist, to determine if the recorded goodwill is impaired. The goodwill impairment test involves a two-step process. Step one estimates the fair value of the reporting unit. If the estimated fair value of the Company's sole reporting unit, the Bank, under step one exceeds the recorded value of the reporting unit, goodwill is not considered impaired and no further analysis is necessary. If the estimated fair value of the Company's sole reporting unit is less than the recorded value, then a step two test, which calculates the fair value of assets and liabilities to calculate an implied value of goodwill, is performed. The Company performed its fiscal year 2016 goodwill impairment test during the quarter ended June 30, 2016 with the assistance of an independent third-party firm specializing in goodwill impairment valuations for financial institutions. The third-party analysis was conducted as of May 31, 2016 and the step one test concluded that the reporting unit's fair value was greater than its recorded value and, therefore, the recorded value of goodwill as of May 31, 2016 was not impaired. Accordingly, step two of the analysis was not necessary. Step one of the goodwill impairment test estimates the fair value of the reporting unit utilizing a discounted cash flow income approach analysis, a public company market approach analysis, a merger and acquisition market approach analysis and a trading price market approach analysis in order to derive an enterprise value for the Company. The discounted cash flow income approach analysis uses a reporting unit's projection of estimated operating results and cash flows and discounts them using a rate that reflects current market conditions. The projection uses management's estimates of economic and market conditions over the projected period including growth rates in loans and deposits, estimates of future expected changes in net interest margins and cash expenditures. Key assumptions used by the Company in its discounted cash flow model (income approach) included an annual loan growth rate that ranged from 3.00% to 3.90% , an annual deposit growth rate that ranged from 2.50% to 3.50% and a return on assets that ranged from 0.90% to 1.10% . In addition to the above projections of estimated operating results, key assumptions used to determine the fair value estimate under this approach were the discount rate of 10.6% and the residual capitalization rate of 7.6% . The discount rate used was the cost of equity capital. The cost of equity capital was based on the capital asset pricing model ("CAPM"), modified to account for a small stock premium. The small stock premium represents the additional return required by investors for small stocks based on the Duff and Phelps 2016 Valuation Handbook . Beyond the approximate five -year forecast period, residual free cash flows were estimated to increase at a constant rate into perpetuity. These cash flows were converted to a residual value using an appropriate residual capitalization rate. The residual capitalization rate was equal to the discount rate minus the expected long-term growth rate of cash flows. Based on historical results, the economic climate, the outlook for the industry and management's expectations, a long-term growth rate of 3.0% was estimated. The public company market approach analysis estimates the fair value by applying cash flow multiples to the reporting unit's operating performance. The multiples are derived from comparable publicly traded companies with operating and investment characteristics similar to those of the Company. Key assumptions used by the Company included the selection of comparable public companies and performance ratios. In applying the public company analysis, the Company selected nine publicly traded institutions based on similar lines of business, markets, growth prospects, risks and firm size. The performance ratios included price to earnings (last twelve months), price to earnings (current year to date), price to book value, price to tangible book value and price to deposits. The merger and acquisition market approach analysis estimates the fair value by using merger and acquisition transactions involving companies that are similar in nature to the Company. Key assumptions used by the Company included the selection of comparable merger and acquisition transactions and the valuation ratios to be used. The analysis used banks located in Washington or Oregon that were acquired after January 1, 2013. The valuation ratios from these transactions for price to earnings and price to tangible book value were then used to derive an estimated fair value of the Company. The trading price market approach analysis used the closing market price at May 31, 2016 of the Company's common stock, traded on the NASDAQ Global Market, to determine the market value of total equity capital. A key assumption used by the Company in the public company market approach analysis and the trading price market approach analysis was the application of a control premium. The Company's common stock is thinly traded, and therefore management believes the trading price reflects a discount for illiquidity. In addition, the trading price of the Company's common stock reflects a minority interest value. To determine the fair market value of a majority interest in the Company's stock, premiums were calculated and applied to the indicated values. Therefore, a control premium was applied to the results of the discounted cash flow income approach analysis, the public company market approach analysis and the trading price market approach analysis because the initial value conclusion was based on minority interest transactions. Merger and acquisition studies were analyzed to conclude that the difference between the acquisition price and a company's stock price prior to acquisition indicates, in part, the price effect of a controlling interest. Based on the evaluation of mergers and acquisition studies, a control premium of 25% was used. A significant amount of judgment is involved in determining if an indicator of goodwill impairment has occurred. Such indicators may include, among others: a significant decline in the expected future cash flows; a sustained, significant decline in the Company's stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse assessment or action by a regulator; and unanticipated competition. Key assumptions used in the annual goodwill impairment test are highly judgmental and include: selection of comparable companies, amount of control premium, projected cash flows and discount rate applied to projected cash flows. Any change in these indicators or key assumptions could have a significant negative impact on the Company's financial condition, impact the goodwill impairment analysis or cause the Company to perform a goodwill impairment analysis more frequently than once per year. As of March 31, 2017, management believed that there had been no events or changes in the circumstances since May 31, 2016 that would indicate a potential impairment of goodwill. No assurances can be given, however, that the Company will not record an impairment loss on goodwill in the future.

Credit Quality Indicators The Company uses credit risk grades which reflect the Company’s assessment of a loan’s risk or loss potential. The Company categorizes loans into risk grade categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors such as the estimated fair value of the collateral. The Company uses the following definitions for credit risk ratings as part of the on-going monitoring of the credit quality of its loan portfolio: Pass: Pass loans are defined as those loans that meet acceptable quality underwriting standards. Watch: Watch loans are defined as those loans that still exhibit acceptable quality, but have some concerns that justify greater attention. If these concerns are not corrected, a potential for further adverse categorization exists. These concerns could relate to a specific condition peculiar to the borrower, its industry segment or the general economic environment. Special Mention: Special mention loans are defined as those loans deemed by management to have some potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of the payment prospects of the loan. Substandard: Substandard loans are defined as those loans that are inadequately protected by the current net worth and paying capacity of the obligor, or of the collateral pledged. Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. If the weakness or weaknesses are not corrected, there is the distinct possibility that some loss will be sustained. Loss: Loans in this classification are considered uncollectible and of such little value that continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this loan even though partial recovery may be realized in the future. At March 31, 2017 and September 30, 2016 , there were no loans classified as loss.

Smaller balance homogeneous loans, such as residential mortgage loans and consumer loans, may be collectively evaluated for impairment. When a loan has been identified as being impaired, the amount of the impairment is measured by using discounted cash flows, except when, as an alternative, the current estimated fair value of the collateral, reduced by estimated costs to sell (if applicable), or observable market price is used. The valuation of real estate collateral is subjective in nature and may be adjusted in future periods because of changes in economic conditions. Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate, in determining the estimated fair value of particular properties. In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals. Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received. When the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest and net deferred loan origination fees or costs), impairment is recognized by creating or adjusting an allocation of the allowance for loan losses and uncollected accrued interest is reversed against interest income. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance.

A troubled debt restructured ("TDR") loan is a loan for which the Company, for reasons related to a borrower’s financial difficulties, grants a significant concession to the borrower that the Company would not otherwise consider. Examples of such concessions include but are not limited to: a reduction in the stated interest rate; an extension of the maturity at an interest rate below current market rates; a reduction in the face amount of the debt; a reduction in the accrued interest; or re-amortizations, extensions, deferrals and renewals. TDR loans are considered impaired and are individually evaluated for impairment. TDR loans are classified as either accrual or non-accrual. TDR loans are classified as non-performing loans unless they have been performing in accordance with their modified terms for a period of at least six months. The Company had $6.83 million and $8.16 million in TDR loans included in impaired loans at March 31, 2017 and September 30, 2016, respectively, and had no commitments at these dates to lend additional funds on these loans. The allowance for loan losses allocated to TDR loans at March 31, 2017 and September 30, 2016 was $28,000 and $465,000 , respectively. There were no TDR loans which incurred a payment default within 12 months of the restructure date during the six months ended March 31, 2017. The following tables set forth information with respect to the Company’s TDR loans by interest accrual status as of March 31, 2017 and September 30, 2016 (dollars in thousands): March 31, 2017 Accruing Non- Accrual Total Mortgage loans: One- to four-family $ 959 $ — $ 959 Commercial 4,475 — 4,475 Land 706 252 958 Consumer loans: Home equity and second mortgage 289 152 441 Total $ 6,429 $ 404 $ 6,833 September 30, 2016 Accruing Non- Accrual Total Mortgage loans: One- to four-family $ 1,350 $ 126 $ 1,476 Commercial 5,268 — 5,268 Land 720 253 973 Consumer loans: Home equity and second mortgage 291 152 443 Total $ 7,629 $ 531 $ 8,160 The were no new TDR loans during the six months ended March 31, 2017 or the year ended September 30, 2016.

Net Income Per Common Share

Earnings Per Share [Abstract]
Net Income Per Common Share	NET INCOME PER COMMON SHARE Basic net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares outstanding during the period, without considering any dilutive items. Diluted net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares and common stock equivalents for items that are dilutive, net of shares assumed to be repurchased using the treasury stock method at the average share price for the Company’s common stock during the period. Common stock equivalents arise from the assumed conversion of outstanding stock options and the outstanding warrant to purchase common stock. Shares owned by the Bank’s ESOP that have not been allocated are not considered to be outstanding for the purpose of computing basic and diluted net income per common share. At March 31, 2017 and 2016, there were 81,944 and 114,588 shares, respectively, that had not been allocated under the Bank’s ESOP. Information regarding the calculation of basic and diluted net income per common share for the three and six months ended March 31, 2017 and 2016 is as follows (dollars in thousands, except per share amounts): Three Months Ended Six Months Ended March 31, 2017 2016 2017 2016 Basic net income per common share computation Numerator – net income $ 3,128 $ 2,380 $ 6,275 $ 4,908 Denominator – weighted average common shares outstanding 7,135,083 6,846,527 6,997,420 6,858,190 Basic net income per common share $ 0.44 $ 0.35 $ 0.90 $ 0.72 Diluted net income per common share computation Numerator – net income $ 3,128 $ 2,380 $ 6,275 $ 4,908 Denominator – weighted average common shares outstanding 7,135,083 6,846,527 6,997,420 6,858,190 Effect of dilutive stock options (1) 159,947 62,028 149,608 57,482 Effect of dilutive stock warrant (2) 84,323 171,450 159,616 166,273 Weighted average common shares outstanding - assuming dilution 7,379,353 7,080,005 7,306,644 7,081,945 Diluted net income per common share $ 0.42 $ 0.34 $ 0.86 $ 0.69 ____________________________________________ (1) For the three and six months ended March 31, 2017 all outstanding options were included in the computation of diluted net income per share. For the three and six months ended March 31, 2016, average options to purchase 14,000 and 84,383 shares of common stock were outstanding but not included in the computation of diluted net income per common share because their effect would have been anti-dilutive. (2) Represented a warrant to purchase 370,899 shares of the Company's common stock at an exercise price of $6.73 per share (subject to anti-dilution adjustments) at any time through December 23, 2018 (the "Warrant"). The Warrant was granted on December 23, 2008 to the U.S. Treasury Department ("Treasury") as part of the Company's participation in the Treasury's Troubled Asset Relief Program ("TARP"). On June 12, 2013, the Treasury sold the Warrant to private investors. On January 31, 2017, the Warrant was exercised and 370,899 shares of the Company's common stock were issued in exchange for $2.50 million .

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS GAAP defines fair value and establishes a framework for measuring fair value. Fair value is the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The three levels for categorizing assets and liabilities under GAAP's fair value measurement requirements are as follows: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2: Significant observable inputs other than quoted prices included within Level 1, such as quoted prices for similar (as opposed to identical) assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the assumptions market participants would use in pricing an asset or liability based on the best information available in the circumstances. The Company's assets measured at fair value on a recurring basis consist of investment securities available for sale. The estimated fair values of MBS are based upon market prices of similar securities or observable inputs (Level 2). The estimated fair values of mutual funds are based upon quoted market prices (Level 1). The Company had no liabilities measured at fair value on a recurring basis at March 31, 2017 and September 30, 2016. The Company's assets measured at estimated fair value on a recurring basis at March 31, 2017 and September 30, 2016 are as follows (dollars in thousands): March 31, 2017 Estimated Fair Value Level 1 Level 2 Level 3 Total Available for sale investment securities MBS: U.S. government agencies $ — $ 328 $ — $ 328 Mutual funds 944 — — 944 Total $ 944 $ 328 $ — $ 1,272 September 30, 2016 Estimated Fair Value Level 1 Level 2 Level 3 Total Available for sale investment securities MBS: U.S. government agencies $ — $ 366 $ — $ 366 Mutual funds 976 — — 976 Total $ 976 $ 366 $ — $ 1,342 There were no transfers among Level 1, Level 2 and Level 3 during the six months ended March 31, 2017 and the year ended September 30, 2016 . The Company may be required, from time to time, to measure certain assets and liabilities at fair value on a non-recurring basis in accordance with GAAP. These include assets that are measured at the lower of cost or market value that were recognized at fair value below cost at the end of the period. The Company uses the following methods and significant assumptions to estimate fair value on a non-recurring basis: Impaired Loans : The estimated fair value of impaired loans is calculated using the collateral value method or on a discounted cash flow basis. The specific reserve for collateral dependent impaired loans is based on the estimated fair value of the collateral less estimated costs to sell, if applicable. In some cases, adjustments are made to the appraised values due to various factors including age of the appraisal, age of comparables included in the appraisal and known changes in the market and in the collateral. Such adjustments may be significant and typically result in a Level 3 classification of the inputs for determining fair value. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Investment Securities Held to Maturity: The estimated fair value of investment securities held to maturity is based upon the assumptions market participants would use in pricing the investment security. Such assumptions include quoted market prices (Level 1), market prices of similar securities or observable inputs (Level 2) and unobservable inputs such as dealer quotes, discounted cash flows or similar techniques (Level 3). OREO and Other Repossessed Assets, net: OREO and other repossessed assets are recorded at estimated fair value less estimated costs to sell. Estimated fair value is generally determined by management based on a number of factors, including third-party appraisals of estimated fair value in an orderly sale. Estimated costs to sell are based on standard market factors. The valuation of OREO and other repossessed assets is subject to significant external and internal judgment (Level 3). The following table summarizes the balances of assets measured at estimated fair value on a non-recurring basis at March 31, 2017 (dollars in thousands): Estimated Fair Value Level 1 Level 2 Level 3 Impaired loans: Mortgage loans: One- to four-family $ — $ — $ 911 Commercial — — 3,904 Land — — 550 Consumer loans: Home equity and second mortgage — — 284 Other — — 11 Total impaired loans — — 5,660 OREO and other repossessed assets — — 3,005 Total $ — $ — $ 8,665 The following table presents quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a non-recurring basis as of March 31, 2017 (dollars in thousands): Estimated Fair Value Valuation Technique(s) Unobservable Input(s) Range Impaired loans $ 5,660 Market approach Appraised value less selling costs NA OREO and other repossessed assets $ 3,005 Market approach Lower of appraised value or listing price less selling costs NA The following table summarizes the balances of assets measured at estimated fair value on a non-recurring basis at September 30, 2016 (dollars in thousands): Estimated Fair Value Level 1 Level 2 Level 3 Impaired loans: Mortgage loans: One- to four-family $ — $ — $ 1,280 Commercial — — 3,330 Land — — 522 Consumer loans: Home equity and second mortgage — — 370 Other — — 17 Total impaired loans — — 5,519 Investment securities – held to maturity: MBS - private label residential — 20 — OREO and other repossessed assets — — 4,117 Total $ — $ 20 $ 9,636 The following table presents quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a non-recurring basis as of September 30, 2016 (dollars in thousands): Estimated Fair Value Valuation Technique(s) Unobservable Input(s) Range Impaired loans $ 5,519 Market approach Appraised value less selling costs NA OREO and other repossessed assets $ 4,117 Market approach Lower of appraised value or listing price less selling costs NA GAAP requires disclosure of estimated fair values for financial instruments. Such estimates are subjective in nature, and significant judgment is required regarding the risk characteristics of various financial instruments at a discrete point in time. Therefore, such estimates could vary significantly if assumptions regarding uncertain factors were to change. In addition, as the Company normally intends to hold the majority of its financial instruments until maturity, it does not expect to realize many of the estimated amounts disclosed. The disclosures also do not include estimated fair value amounts for certain items which are not defined as financial instruments but which may have significant value. The Company does not believe that it would be practicable to estimate a representational fair value for these types of items as of March 31, 2017 and September 30, 2016. Because GAAP excludes certain items from fair value disclosure requirements, any aggregation of the fair value amounts presented would not represent the underlying value of the Company. The following methods and assumptions were used by the Company in estimating fair value of its other financial instruments: Cash and Cash Equivalents: The estimated fair value of financial instruments that are short-term or re-price frequently and that have little or no risk are considered to have an estimated fair value equal to the recorded value. CDs Held for Investment: The estimated fair value of financial instruments that are short-term or re-price frequently and that have little or no risk are considered to have an estimated fair value equal to the recorded value. Investment Securities: See descriptions above. FHLB Stock: No ready market exists for this stock, and it has no quoted market value. However, redemption of this stock has historically been at par value. Accordingly, par value is deemed to be a reasonable estimate of fair value. Loans Receivable, Net: The fair value of non-impaired loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers for the same remaining maturities. Prepayments are based on the historical experience of the Bank. Fair values for impaired loans are estimated using the methods described above. Loans Held for Sale: The estimated fair value is based on quoted market prices (for one-to four-family loans) and the guaranteed value of U.S. Small Business Administration ("SBA") loans (made to small businesses under the SBA's 7(a) loan programs). Quoted market prices are obtained from the Federal Home Loan Mortgage Corporation ("Freddie Mac") and the FHLB. Accrued Interest: The recorded amount of accrued interest approximates the estimated fair value. Deposits : The estimated fair value of deposits with no stated maturity date is deemed to be the amount payable on demand. The estimated fair value of fixed maturity certificates of deposit is computed by discounting future cash flows using the rates currently offered by the Bank for deposits of similar remaining maturities. FHLB Borrowings: The estimated fair value of FHLB borrowings is computed by discounting the future cash flows of the borrowings at a rate which approximates the current offering rate of the borrowings with a comparable remaining life. Off-Balance-Sheet Instruments: Since the majority of the Company’s off-balance-sheet instruments consist of variable-rate commitments, the Company has determined that they do not have a distinguishable estimated fair value. The recorded amounts and estimated fair values of financial instruments were as follows as of March 31, 2017 and September 30, 2016 (dollars in thousands): March 31, 2017 Fair Value Measurements Using: Recorded Amount Estimated Fair Value Level 1 Level 2 Level 3 Financial assets Cash and cash equivalents $ 148,040 $ 148,040 $ 148,040 $ — $ — CDs held for investment 52,934 52,934 52,934 — — Investment securities 8,598 9,317 3,935 5,382 — FHLB stock 2,307 2,307 2,307 — — Loans receivable, net 676,079 675,019 — — 675,019 Loans held for sale 5,798 5,878 5,878 — — Accrued interest receivable 2,443 2,443 2,443 — — Financial liabilities Deposits: Non-interest-bearing demand 186,239 186,239 186,239 — — Interest-bearing 622,613 622,696 480,461 — 142,235 Total deposits 808,852 808,935 666,700 — 142,235 FHLB borrowings 30,000 30,226 — 30,226 — Accrued interest payable 253 253 253 — — September 30, 2016 Fair Value Measurements Using: Recorded Amount Estimated Fair Value Level 1 Level 2 Level 3 Financial assets Cash and cash equivalents $ 108,941 $ 108,941 $ 108,941 $ — $ — CDs held for investment 53,000 53,000 53,000 — — Investment securities 8,853 9,737 4,029 5,708 — FHLB stock 2,204 2,204 2,204 — — Loans receivable, net 663,146 671,017 — — 671,017 Loans held for sale 3,604 3,714 3,714 — — Accrued interest receivable 2,348 2,348 2,348 — — Financial liabilities Deposits: Non-interest-bearing demand 172,283 172,283 172,283 — — Interest-bearing 589,251 589,762 441,277 — 148,485 Total deposits 761,534 762,045 613,560 — 148,485 FHLB borrowings 30,000 30,684 — 30,684 — Accrued interest payable 247 247 247 — — The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. As a result, the estimated fair value of the Company’s financial instruments will change when interest rate levels change, and that change may either be favorable or unfavorable to the Company. Management attempts to match maturities of assets and liabilities to the extent believed necessary to appropriately manage interest rate risk. However, borrowers with fixed interest rate obligations are less likely to prepay in a rising interest rate environment and more likely to prepay in a falling interest rate environment. Conversely, depositors who are receiving fixed interest rates are more likely to withdraw funds before maturity in a rising interest rate environment and less likely to do so in a falling interest rate environment. Management monitors interest rates and maturities of assets and liabilities, and attempts to manage interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of this ASU is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract and estimating the amount of variable consideration to include in the transaction price related to each separate performance obligation. This ASU is effective for annual periods beginning after December 15, 2017, including interim periods within that reporting period. The Company's primary source of revenue is interest income, which is recognized when earned and is deemed to be in compliance with this ASU. Accordingly, the adoption of ASU No. 2014-09 is not expected to have a material impact on the Company's consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . The main provisions of this ASU address the valuation and impairment of certain equity investments along with simplified disclosures about the fair value of financial instruments. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The adoption of ASU No. 2016-01 is not expected to have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . This ASU is intended to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The principal change required by this ASU relates to lessee accounting, and is that for operating leases, a lessee is required to (1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, (2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and (3) classify all cash payments within operating activities in the statement of cash flows. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. This ASU also changes disclosure requirements related to leasing activities and requires certain qualitative disclosures along with specific quantitative disclosures. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of the amendments in this ASU is permitted. The effect of adoption will depend on leases at the time of adoption. Once adopted, the Company expects to report higher assets and liabilities as a result of including right-of-use assets and lease liabilities related to certain banking offices and certain equipment under noncancelable operating lease agreements, however, based on current leases the adoption of ASU No. 2016-02 is not expected to have a material impact on the Company's future consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. This ASU includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. The Company is currently evaluating the impact that the adoption of ASU No. 2016-09 will have on the Company's future consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses . This ASU replaces the existing incurred losses methodology for estimating allowances with a current expected credit losses methodology with respect to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held to maturity investment securities and off-balance sheet commitments. In addition, this ASU requires credit losses relating to available for sale debt securities to be recorded through an allowance for credit losses rather than a reduction of the carrying amount. ASU No. 2016-13 also changes the accounting for purchased credit-impaired debt securities and loans. The standard retains many of the current disclosure requirements in current GAAP and expands certain disclosure requirements. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of ASU No. 2016-13 will have on the Company’s future consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment . This ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under ASU No. 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. ASU No. 2017-04 will be effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early application of this ASU is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU No. 2017-04 is not expected to have a material impact on the Company's future consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . The ASU shortens the amortization period for certain callable debt securities held at a premium. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company's future consolidated financial statements.

Summary Of Significant Accoun19

Summary Of Significant Accounting Policies (Policies)	6 Months Ended
	Mar. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying unaudited consolidated financial statements for Timberland Bancorp, Inc. (“Company”) were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with instructions for Form 10-Q and, therefore, do not include all disclosures necessary for a complete presentation of consolidated financial condition, results of operations, and cash flows in conformity with GAAP. However, all adjustments which are, in the opinion of management, necessary for a fair presentation of the interim consolidated financial statements have been included. All such adjustments are of a normal recurring nature. The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2016 (“2016 Form 10-K”). The unaudited consolidated results of operations for the six months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the entire fiscal year ending September 30, 2017.
Principles of Consolidation	Principles of Consolidation: The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Timberland Bank (“Bank”), and the Bank’s wholly-owned subsidiary, Timberland Service Corporation. All significant intercompany transactions and balances have been eliminated in consolidation.
Operating Segment	Operating Segment: The Company has one reportable operating segment which is defined as community banking in western Washington under the operating name, “Timberland Bank.”
Use of Estimates	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Reclassification	Certain prior period amounts have been reclassified to conform to the March 31, 2017 presentation with no change to net income or total shareholders’ equity as previously reported.
