            Report of Independent Registered Public Accounting Firm



To the Audit Committee of the
Timberland Bank 401(k) Profit Sharing Plan
Hoquiam, Washington


We have audited the accompanying statements of net assets available for
benefits of Timberland Bank 401(k) Profit Sharing Plan (the Plan) as of
September 30, 2004 and 2003, and the related statement of changes in net
assets available for benefits for the year ended September 30, 2004.  These
financial statements are the responsibility of the Plan's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with auditing standards of the Public
Company Accounting Oversight Board (United States).  Those standards require
that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement.  An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements.  An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation.  We believe
that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial status of the Plan as of September 30,
2004 and 2003, and the changes in its financial status for the year ended
September 30, 2004, in conformity with U.S. generally accepted accounting
principles.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedule as of
September 30, 2004 is presented for the purpose of additional analysis and is
not a required part of the basic financial statements, but is supplementary
information required by the United States Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974.  This supplemental schedule is the responsibility of the
Plan's management.  The supplemental schedule has been subjected to the
auditing procedures applied in the audits of the basic financial statements
and, in our opinion, is fairly stated, in all material respects, in relation
to the basic financial statements taken as a whole.

Timberland Bank 401(k) Profit Sharing Plan
September 30, 2004 and 2003


Note 1 - Description of the Plan

The following description of Timberland Bank 401(k) Profit Sharing Plan (the
Plan) provides only general information.  Participants should refer to the
Plan agreement for a more complete description of the Plan's provisions.

General

The Plan is a defined contribution plan covering substantially all full-time
employees of Timberland Bank (the Company) who have one year of service and
are age twenty-one or older.  It is subject to the provisions of the Employee
Retirement Income Security Act of 1974 (ERISA).  The Company is the wholly
owned subsidiary of Timberland Bancorp, Inc.

Contributions and Participant Investment Options

The Plan participants may contribute up to the maximum of pretax annual
compensation as set by law.  Participants may also contribute amounts
representing distributions from other qualified defined benefit or defined
contribution plans.  The Company makes an annual safe harbor contribution of
3% of eligible compensation, with additional amounts contributed at the option
of its board of directors.  For the year ended September 30, 2004, the Company
contributed a total of 10% of total eligible participant compensation.

Participants must direct their salary deferral contributions and their
allocated share of the safe harbor contribution and the employer
contributions, if any, into a variety of investment choices, as made available
and determined by the Plan administrator, which are more fully described in
the Plan's literature.

Participant Accounts

Each participant's account is credited with the participant's contribution and
allocations of:  (a) the Company's contributions, (b) Plan earnings, and (c)
forfeitures of terminated participants' nonvested accounts and charged with an
allocation of administrative expenses.  Allocations are based on participant
earnings or account balances, as defined.  The benefit to which a participant
is entitled is the benefit that can be provided from the participant's vested
account.

Vesting

Participants are immediately vested in all deferral, rollover and safe harbor
contributions, plus actual earnings thereon.  Vesting in the Company's
discretionary contribution portion of accounts, plus earnings thereon, is
based on years of credited service.  Participants are fully vested after six
years of credited service.  A participant's accrued benefit derived from
employer contributions is also 100% nonforfeitable upon attaining age 65, or
if the participant's separation from service is a result of death or
disability.

Notes to Financial Statements
- ------------------------------------------------------------------------------


Timberland Bank 401(k) Profit Sharing Plan
September 30, 2004 and 2003


Note 1 - Description of the Plan (concluded)

Payment of Benefits

On termination of service, a participant with an accrued benefit of $5,000 or
less will receive a lump-sum amount equal to the value of the vested interest
in their account.  The distribution date will be the earliest administratively
feasible date for participants that attain normal retirement age or age 55
with 10 years of service.  Distributions for participants that do not meet
these requirements will be made as soon as administratively feasible in the
Plan year following separation of service.  Participants with an accrued
benefit in excess of $5,000 may leave the funds in the Plan or elect to
receive a lump-sum distribution.

Forfeited Accounts

At September 30, 2004, forfeited, nonvested accounts totaled $27,721.  These
accounts will be reallocated to participants in the same manner as employer
contributions.


Note 2 - Summary of Accounting Policies

Basis of Accounting

The financial statements of the Plan are prepared under the accrual method of
accounting.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and changes
therein, and the disclosure of contingent assets and liabilities.  Actual
results could differ from these estimates.

Investment Valuation and Income Recognition

The Plan's investments are stated at fair value.  Quoted market prices are
used to value common stock and mutual funds.  Shares of mutual funds are
valued at the net asset value of shares held by the Plan at year-end.
Purchases and sales of securities are recorded on the trade-date basis.
Dividends are recorded on the ex-dividend date.

Payment of Benefits

Benefits are recorded when paid.

                                                           2004        2003

  First American Strategy Growth Allocation Fund          732,259      311,848

  First American Strategy Aggressive Allocation Fund      375,360      215,748

                                                       $7,251,672   $6,500,372

**   The fund balance has been included in other - mutual funds, as the fund
     did not exceed 5% of the Plan's net assets at year-end.

During 2004 the Plan's investments, including gains and losses on investments
bought and sold, as well as held during the year, appreciated in value by
$34,350 as follows:

Mutual funds                                                        $142,403
Common stock                                                        (108,053)

  Net appreciation in fair value of investments                    $  34,350


Note 4 - Plan Termination

Although it has not expressed any intent to do so, the Company has the right
under the Plan to discontinue its contributions at any time and to terminate
the Plan, subject to the provisions of ERISA.  In the event of Plan
termination, participants will become 100% vested in their accounts.  Any
unallocated assets of the Plan shall be allocated to participant accounts and
distributed in such a manner as the Company may determine.

Notes to Financial Statements
- ------------------------------------------------------------------------------


Timberland Bank 401(k) Profit Sharing Plan
September 30, 2004 and 2003


Note 5 - Tax Status/Non-Standardized Prototype Plan

Effective October 1, 1997, the Plan adopted a nonstandardized form of a
prototype plan sponsored by Actuarial Planning Group, Inc.  The prototype plan
received an opinion letter, dated August 30, 2001, from the Internal Revenue
Service which stated that the Plan, as then designed, was in compliance with
the applicable requirements of the Internal Revenue Code.  The Plan has been
amended subsequent to receiving the opinion letter.  However, the Plan
administrator believes the Plan is designed and is being operated in
compliance with the applicable provisions of the Internal Revenue Code.

The Internal Revenue Service is currently examining the Plan's records and tax
filings for the year ended September 30, 2002.  Management has not received
notification of any issues and believes there will be no findings that would
affect reported amounts or the Plan's exempt status.


Note 6 - Administration of Plan Assets

Certain Plan investments are shares of mutual funds managed by US Bank.  US
Bank is the trustee, as defined by the Plan; therefore, these transactions
qualify as party-in-interest transactions.  Fees paid by the Plan for
investment management services amounted to $22,467 for the year ended
September 30, 2004.

Certain administrative functions of the Plan are performed by officers or
employees of the Company.  No such officers or employees receive compensation
from the Plan.  Other administrative and management fees of the Plan are paid
directly by the Company.


Note 7 - Risks and Uncertainties

The Plan invests in various investment securities.  Investment securities are
exposed to various risks, such as interest rate, market and credit risks.  Due
to the level of risk associated with certain investment securities, it is at
least reasonably possible that changes in the values of investment securities
will occur in the near term, and that such changes could materially affect
participant account balances and the amounts reported on the statements of net
assets available for benefits.
