LETTER TO SHAREHOLDERS

                                                                   July 29, 2005

DEAR SHAREHOLDER:

For the six months ended June 30, 2005, The Indonesia Fund, Inc. (the "Fund")
had a gain in its net asset value ("NAV") of 16.73%, vs. an increase of 10.20%
for the Morgan Stanley Capital International Indonesia Index.* Based on market
price, the Fund's shares rose 15.19% during this six month period. As a result,
the Fund's discount to its NAV stood at 1.52% on June 30, 2005, compared with a
discount of 0.20% at the beginning of the period.

THE MARKET: LEADING AN OUTPERFORMING ASSET CLASS

The period was a positive one for emerging stock markets as a group, both in
absolute terms and compared with developed stock markets, at least for
US-dollar-based investors. Emerging markets initially rallied, but then turned
sharply down in March on worries that rising US interest rates could threaten
global growth. These fears subsided in the latter part of the period, with
inflation appearing to be under control and as long-term US interest rates
remained fairly stable. Investors' appetite for risk in general returned, and
emerging markets ended the period on a solid note.

Indonesia outperformed the broad emerging stock market group, aided by an
accommodative monetary policy, high commodity prices and an increase of flows
into the market. Weakness in the country's rupiah currency eroded some of the
strong gains generated locally, but the market nonetheless outperformed in
dollar terms as well by a handy margin.

THE PORTFOLIO: AIDED BY STOCK SELECTION

The Fund's outperformance was attributable in part to good stock selection in
the food, beverages & tobacco sector. Most specifically, we had a large absolute
and relative weighting in longtime holding PT Hanjaya Mandala Sampoerna Tbk
("HM Sampoerna"), which rallied on Philip Morris' takeover bid. We accepted the
offer and sold the position in May.

Elsewhere, the Fund's investments in the materials and telecommunications
sectors aided its performance. The Fund's overweightings in the capital goods
and food, beverages & tobacco sectors also added value, as these areas of the
market outperformed in the period. The Fund's underweighting in the bank sector,
which struggled amid a rising cost of capital, proved beneficial as well. On the
negative side, relatively speaking, the Fund's energy and technology-related
stocks underperformed.

With regard to noteworthy recent portfolio activity, we sold HM Sampoerna late
in the period, as noted. This was an approximately 20% weighting in the Fund at
the time. We reinvested the proceeds by period-end, favoring telecom,
financials, industrial and consumer discretionary companies.

A MIXED BAG

In the wake of a solid six months for Indonesia's stock market, which followed a
robust gain in 2004, there are a number of issues to consider as we look ahead:

- -  Employment remains a concern, with not enough jobs created to satisfy the
   roughly 40 million unemployed or underemployed

- -  Ongoing fuel subsidies, a popular program, will likely continue to strain the
   government's finances and jeopardize the country's foreign exchange reserves

- -  The President's popularity has declined to its lowest point since last year's
   October election victory

- -  Core inflation has remained high, at about 8%. Indonesian authorities have
   been edging interest rates higher with an 8.5% intermediate-term target

- -  In continuing efforts to eradicate corruption, the Anti Corruption Committee
   has cast its net far and wide, targeting government officials and departments
   including the General Election Commission

- -  On the positive side, Indonesia's economy appears to remain healthy, with
   first-quarter GDP rising 6.4% on an annualized basis

- -  The composition of GDP in Indonesia now appears to be more balanced, with
   capital investment rising and consumption declining amid higher interest
   rates

- -  Excess liquidity in Indonesia and the region could continue to be a positive
   market factor in our view

Given these issues, on balance we have chosen to adopt a more cautious stance.
Indonesian assets accounted for about 80% to 85% of the Fund as of the end of
the period, down from approximately 90% at the beginning of the year.

Sincerely,

/s/ Boon Hong Yeo

THE INDONESIA FUND, INC.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE A. ORGANIZATION

The Indonesia Fund, Inc. (the "Fund") was incorporated in Maryland on January 8,
1990 and commenced investment operations on March 9, 1990. The Fund is
registered under the Investment Company Act of 1940, as amended, as a
closed-end, non-diversified management investment company.

NOTE B. SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES: The preparation of financial statements in conformity with
accounting principles generally accepted in the United States of America
("GAAP") requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of contingent assets
and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Actual results could
differ from those estimates.

SECURITY VALUATION: The net asset value of the Fund is determined daily as of
the close of regular trading on the New York Stock Exchange, Inc. (the
"Exchange") on each day the Exchange is open for business. The Fund's equity
investments are valued at market value, which is generally determined using the
closing price on the exchange or market on which the security is primarily
traded at the time of valuation (the "Valuation Time"). If no sales are
reported, equity investments are generally valued at the most recent bid
quotation as of the Valuation Time or at the lowest ask quotation in the case of
a short sale of securities. Debt securities with a remaining maturity greater
than 60 days are valued in accordance with the price supplied by a pricing
service, which may use a matrix, formula or other objective method that takes
into consideration market indices, yield curves and other specific adjustments.
Debt obligations that will mature in 60 days or less are valued on the basis of
amortized cost, which approximates market value, unless it is determined that
this method would not represent fair value.

Securities and other assets for which market quotations are not readily
available, or whose values have been materially affected by events occurring
before the Fund's Valuation Time, but after the close of the securities' primary
market, are valued at fair value as determined in good faith by, or under the
direction of, the Board of Directors under procedures established by the Board
of Directors. The Fund may utilize a service provided by an independent third
party which has been approved by the Board of Directors to fair value certain
securities. The Fund's estimate of fair value assumes a willing buyer and a
willing seller neither acting under a compulsion to buy or sell.

SHORT-TERM INVESTMENTS: The Fund sweeps available U.S. dollar cash into a
short-term time deposit available through Brown Brothers Harriman & Co., the
Fund's custodian. The Fund also sweeps available cash denominated in Indonesian
rupiah into a short-term deposit issued by Citibank N.A., Jakarta. These
short-term time deposits are variable rate accounts classified as short-term
investments.

INVESTMENT TRANSACTIONS AND INVESTMENT INCOME: Investment transactions are
accounted for on a trade date basis. The cost of investments sold is determined
by use of the specific identification method for both financial reporting and
U.S. income tax purposes. Interest income is accrued as earned; dividend income
is recorded on the ex-dividend date.

TAXES: No provision is made for U.S. income or excise taxes as it is the Fund's
intention to continue to qualify as a regulated investment company and to make
the requisite distributions to its shareholders sufficient to relieve it from
all or substantially all U.S. income and excise taxes.

                                       12
<Page>

Income received by the Fund from sources within Indonesia and other foreign
countries may be subject to withholding and other taxes imposed by such
countries.

FOREIGN CURRENCY TRANSLATIONS: The books and records of the Fund are maintained
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on
the following basis:

      (I) market value of investment securities, assets and liabilities at the
          valuation date rate of exchange; and

     (II) purchases and sales of investment securities, income and expenses at
          the relevant rates of exchange prevailing on the respective dates of
          such transactions.

The Fund does not isolate that portion of gains and losses on investments in
equity securities which is due to changes in the foreign exchange rates from
that which is due to changes in market prices of equity securities. Accordingly,
realized and unrealized foreign currency gains and losses with respect to such
securities are included in the reported net realized and unrealized gains and
losses on investment transactions balances.

The Fund reports certain foreign currency related transactions and foreign taxes
withheld on security transactions as components of realized gains for financial
reporting purposes, whereas such foreign currency related transactions are
treated as ordinary income for U.S. income tax purposes.

Net unrealized currency gains or losses from valuing foreign currency
denominated assets and liabilities at period end exchange rates are reflected as
a component of net unrealized appreciation/depreciation in value of investments,
and translation of other assets and liabilities denominated in foreign
currencies.

Net realized foreign exchange gains or losses represent foreign exchange gains
and losses from transactions in foreign currencies and forward foreign currency
contracts, exchange gains or losses realized between the trade date and
settlement date on security transactions, and the difference between the amounts
of interest and dividends recorded on the Fund's books and the U.S. dollar
equivalent of the amounts actually received.

DISTRIBUTIONS OF INCOME AND GAINS: The Fund distributes at least annually to
shareholders substantially all of its net investment income and net realized
short-term capital gains, if any. The Fund determines annually whether to
distribute any net realized long-term capital gains in excess of net realized
short-term capital losses, including capital loss carryovers, if any. An
additional distribution may be made to the extent necessary to avoid the payment
of a 4% U.S. federal excise tax. Dividends and distributions to shareholders are
recorded by the Fund on the ex-dividend date.

The character of distributions made during the year from net investment income
or net realized gains may differ from their ultimate characterization for U.S.
income tax purposes due to U.S. generally accepted accounting principles/tax
differences in the character of income and expense recognition.

OTHER: The Fund may invest in securities of foreign countries and governments
which involve certain risks in addition to those inherent in domestic
investments. Such risks generally include, among others, currency risks
(fluctuations in currency exchange rates), information risk (key information may
be inaccurate or unavailable) and political risk (expropriation, nationalization
or the imposition of capital or currency controls or punitive taxes). Other
risks of investing in foreign securities include liquidity and valuation risks.

Securities denominated in currencies other than U.S. dollars are subject to
changes in value due to fluctuations in exchange rates.

Investment in Indonesian and other foreign securities requires consideration of
certain factors that are not normally involved in investments in U.S.
securities. The Indonesian securities market is an emerging market characterized
by a small number of company listings, high price volatility and a relatively
illiquid secondary trading environment. These factors, coupled with restrictions
on investment by foreigners and other factors, limit the supply of securities
available for investment by the Fund. This will affect the rate at which the
Fund is able to invest in Indonesian and other foreign securities, the purchase
and sale prices for such securities and the timing of purchases and sales.

The limited liquidity of the Indonesian and other foreign securities markets may
also affect the Fund's ability to acquire or dispose of securities at a price
and time that it wishes to do so. Accordingly, in periods of rising market
prices, the Fund may be unable to participate in such price increases fully to
the extent that it is unable to acquire desired portfolio positions quickly;
conversely the Fund's inability to dispose fully and promptly of positions in
declining markets will cause its net asset value to decline as the value of
unsold positions is marked to lower prices.

NOTE C. AGREEMENTS

adviser with respect to all investments. CSAM receives as compensation for its

Credit Suisse Asset Management (Australia) Limited ("Sub-Adviser") serves as the
Fund's sub-investment adviser. CSAM currently pays the Sub-Adviser on a
quarterly basis a fee of 90% of the net quarterly amount received by CSAM as the
Fund's investment adviser. The Fund does not pay the Sub-Adviser.

Bear Stearns Funds Management Inc. ("BSFM") serves as the Fund's administrator.
The Fund pays BSFM a monthly fee that is calculated weekly based on the Fund's
average weekly net assets. For the six months ended June 30, 2005, BSFM earned

NOTE F. CREDIT FACILITY

The Fund, together with other funds/portfolios advised by CSAM (collectively,
the "Participating Funds"), participates in a $75 million committed, unsecured,
line of credit facility ("Credit Facility") with Deutsche Bank, A.G. as
administrative agent and syndication agent and State Street Bank and Trust
Company as operations agent for temporary or emergency purposes. Under the terms
of the Credit Facility, the Participating Funds pay an aggregate commitment fee
at a rate of

                                       14
<Page>

0.10% per annum on the average unused amount of the Credit Facility, which is
allocated among the Participating Funds in such manner as is determined by the
governing Boards of the Participating Funds. In addition, the Participating
Funds pay interest on borrowings at the Federal Funds rate plus 0.50%. During
the six months ended June 30, 2005, the Fund had no borrowings under the Credit
Facility.

NOTE G. FEDERAL INCOME TAXES

Income and capital gain distributions are determined in accordance with federal
income tax regulations, which may differ from GAAP. These differences are
primarily due to foreign currency transactions, post-October losses on foreign
currency transactions and losses deferred due to wash sales.

The tax character of the $785,289 dividends paid during the year ended December
31, 2004 was ordinary income.

At December 31, 2004, the Fund had a capital loss carryover for U.S. federal
income tax purposes of $26,646,783 of which $3,265,956 expires in 2005;
$13,254,308 expires in 2006; $1,782,694 expires in 2007; $5,937,713 expires in
2008 ($2,211,704 of capital loss carryforward expiring in 2008 is subject to
annual limitations of $292,278), $1,720,106 expires in 2009 and $686,006 expires
in 2010. For the year ended December 31, 2004, the Fund utilized capital loss
carryovers of $3,110,515. It is uncertain whether the Fund will be able to
realize the benefits before they expire.

At December 31, 2004, the identified cost for federal income tax purposes, as
well as the gross unrealized appreciation from investments for those securities
having an excess of value over cost, gross unrealized depreciation from
investments for those securities having an excess of cost over value and the net
unrealized appreciation from investments were $35,034,744, $14,431,126,
$(369,205), and $14,061,921, respectively.

DESCRIPTION OF INVESTLINK(SM) PROGRAM (UNAUDITED)

The InvestLink(SM) Program is sponsored and administered by EquiServe Trust
Company, N.A., not by The Indonesia Fund, Inc. (the "Fund"). EquiServe Trust
Company, N.A., will act as program administrator (the "Program Administrator")
of the InvestLink(SM) Program (the "Program"). The purpose of the Program is to
provide existing shareholders with a simple and convenient way to invest
additional funds and reinvest dividends in shares of the Fund's common stock
("Shares") at prevailing prices, with reduced brokerage commissions and fees.

In order to participate in the Program, you must be a registered holder of at
least one Share of stock of the Fund. Purchases of Shares with funds from a
participant's cash payment or automatic account deduction will begin on the next
day on which funds are invested. All cash payments must be drawn on a U.S. bank
and payable in U.S. dollars. Checks must be made payable to EquiServe. If a
participant selects the dividend reinvestment option, automatic investment of
dividends generally will begin with the next dividend payable after the Program
Administrator receives his enrollment form. Once in the Program, a person will
remain a participant until he terminates his participation or sells all Shares
held in his Program account, or his account is terminated by the Program
Administrator. A participant may change his investment options at any time by
requesting a new enrollment form and returning it to the Program Administrator.

A participant will be assessed certain charges in connection with his
participation in the Program. All optional cash deposit investments will be
subject to a service charge. Sales processed through the Program will have a
service fee deducted from the net proceeds, after brokerage commissions. In
addition to the transaction charges outlined above, participants will be
assessed per share processing fees (which include brokerage commissions.)
Participants will not be charged any fee for reinvesting dividends.

The number of Shares to be purchased for a participant depends on the amount of
his dividends, cash payments or bank account or payroll deductions, less
applicable fees and commissions, and the purchase price of the Shares. The
investment date for cash payments is the 25th day of each month (or the next
trading day if the 25th is not a trading day). The investment date for dividend
reinvestment is the dividend payment date. The Program Administrator uses
dividends and funds of participants to purchase Shares of the Fund in the open
market. Such purchases will be made by participating brokers as agent for the
participants using normal cash settlement practices. All Shares purchased
through the Program will be allocated to participants as of the settlement date,
which is usually three business days from the purchase date. In all cases,
transaction processing will occur within 30 days of the receipt of funds, except
where temporary curtailment or suspension of purchases is necessary to comply
with applicable provisions of the Federal Securities laws or when unusual market
conditions make prudent investment impracticable. In the event the Program
Administrator is unable to purchase Shares within 30 days of the receipt of
funds, such funds will be returned to the participants.

The average price of all Shares purchased by the Program Administrator with all
funds received during the time period from two business days preceding any
investment date up to the second business day preceding the next investment date
shall be the price per share allocable to a participant in connection with the
Shares purchased for his account with his funds or dividends received by the
Program Administrator during such time period. The average price of all Shares
sold by the Program Administrator pursuant to sell orders received during such
time period shall be the price per share allocable to a participant in
connection with the Shares sold for his account pursuant to his sell orders
received by the Program Administrator during such time period. All sale requests
having an

                                       18
<Page>

anticipated market value of $100,000.00 or more are expected to be submitted in
written form. In addition, all sale requests received by the Program
Administrator within thirty (30) days of an address change are expected to be
submitted in written form.

EquiServe Trust Company, N.A., as Program Administrator, administers the Program
for participants, keeps records, sends statements of account to participants and
performs other duties relating to the Program. Each participant in the Program
will receive a statement of his account following each purchase of Shares. The
statements will also show the amount of dividends credited to such participant's
account (if applicable), as well as the fees paid by the participant. In
addition, each participant will receive copies of the Fund's annual and
semi-annual reports to shareholders, proxy statements and, if applicable,
dividend income information for tax reporting purposes.

If the Fund is paying dividends on the Shares, a participant will receive
dividends through the Program for all Shares held on the dividend record date on
the basis of full and fractional Shares held in his account, and for all other
Shares of the Fund registered in his name. The Program Administrator will send
checks to the participants for the amounts of their dividends that are not to be
automatically reinvested at no cost to the participants.

Shares of the Fund purchased under the Program will be registered in the name of
the accounts of the respective participants. Unless requested, the Fund will not
issue to participants certificates for Shares of the Fund purchased under the
Program. The Program Administrator will hold the Shares in book-entry form until
a Program participant chooses to withdraw his Shares or terminate his
participation in the Program. The number of Shares purchased for a participant's
account under the Program will be shown on his statement of account. This
feature protects against loss, theft or destruction of stock certificates.

A participant may withdraw all or a portion of the Shares from his Program
account by notifying the Program Administrator. After receipt of a participant's
request, the Program Administrator will issue to such participant certificates
for the whole Shares of the Fund so withdrawn or, if requested by the
participant, sell the Shares for him and send him the proceeds, less applicable
brokerage commissions, fees, and transfer taxes, if any. If a participant
withdraws all full and fractional Shares in his Program account, his
participation in the Program will be terminated by the Program Administrator. In
no case will certificates for fractional Shares be issued. The Program
Administrator will convert any fractional Shares held by a participant at the
time of his withdrawal to cash.

Participation in any rights offering, dividend distribution or stock split will
be based upon both the Shares of the Fund registered in participants' names and
the Shares (including fractional Shares) credited to participants' Program
accounts. Any stock dividend or Shares resulting from stock splits with respect
to Shares of the Fund, both full and fractional, which participants hold in
their Program accounts and with respect to all Shares registered in their names
will be automatically credited to their accounts.

All Shares of the Fund (including any fractional share) credited to his account
under the Program will be voted as the participant directs. The participants
will be sent the proxy materials for the annual meetings of shareholders. When a
participant returns an executed proxy, all of such Shares will be voted as
indicated. A participant may also elect to vote his Shares in person at the
Shareholders' meeting.

                                       19
<Page>

A participant will receive tax information annually for his personal records and
to help him prepare his U.S. federal income tax return. The automatic
reinvestment of dividends does not relieve him of any income tax which may be
payable on dividends. For further information as to tax consequences of
participation in the Program, participants should consult with their own tax
advisors.

The Program Administrator in administering the Program will not be liable for
any act done in good faith or for any good faith omission to act. However, the
Program Administrator will be liable for loss or damage due to error caused by
its negligence, bad faith or willful misconduct. Shares held in custody by the
Program Administrator are not subject to protection under the Securities
Investors Protection Act of 1970.

The participant should recognize that neither the Fund nor the Program
Administrator can provide any assurance of a profit or protection against loss
on any Shares purchased under the Program. A participant's investment in Shares
held in his Program account is no different than his investment in directly held
Shares in this regard. The participant bears the risk of loss and the benefits
of gain from market price changes with respect to all of his Shares. Neither the
Fund nor the Program Administrator can guarantee that Shares purchased under the
Program will, at any particular time, be worth more or less than their purchase
price. Each participant must make an independent investment decision based on
his own judgment and research.

While the Program Administrator hopes to continue the Program indefinitely, the
Program Administrator reserves the right to suspend or terminate the Program at
any time. It also reserves the right to make modifications to the Program.
Participants will be notified of any such suspension, termination or
modification in accordance with the terms and conditions of the Program. The
Program Administrator also reserves the right to terminate any participant's
participation in the Program at any time. Any question of interpretation arising
under the Program will be determined in good faith by the Program Administrator
and any such good faith determination will be final.

Any interested shareholder may participate in the Program. All other cash
payments or bank account deductions must be at least $100.00, up to a maximum of
$100,000.00 annually. An interested shareholder may join the Program by reading
the Program description, completing and signing the enrollment form and
returning it to the Program Administrator. The enrollment form and information
relating to the Program (including the terms and conditions) may be obtained by
calling the Program Administrator at one of the following telephone numbers:
(800) 730-6001 (U.S. and Canada) or (781) 575-3100 (outside U.S. and Canada).
All correspondence regarding the Program should be directed to: EquiServe Trust
Company N.A., InvestLink(SM) Program, P.O. Box 43010, Providence,
RI 02940-3010.

InvestLink is a service mark of EquiServe Trust Company, N.A.
