     This Amendment No. 11 amends and supplements Items 2 and 5 and Annex A of
the Statement on Schedule 13D of Bankgesellschaft Berlin AG (the "Bank") with
respect to the shares of Common Stock, par value $.01 per share (the "Common
Stock"), of the Aberdeen Australia Equity Fund, Inc. (the "Fund"). Annex A sets
forth the name, address and principal occupation of each director and executive
officer of the Bank and the name, address, jurisdiction of incorporation and
principal business of each shareholder of the Bank who may be deemed to be in
control of the Bank. All of the individuals listed on Annex A are citizens of
the Federal Republic of Germany. Items not included in this amendment are not
amended and remain as previously reported.

ITEM 2. IDENTITY AND BACKGROUND

     We note that every time we amend Annex A to the Bank's Schedule 13D, we
automatically reiterate, unless otherwise explicitly set forth in such
amendment, the statement made in Item 2 of the Bank's Amendment No. 7 to its
Schedule 13D. Such statement is as follows: Based on the information about the
persons listed on Annex A that is available to the Bank pursuant to German labor
law (including a police certificate of no criminal record), the Bank is unaware
of any information that would render incorrect the statements in (d) and (e) of
Item 2 of the Bank's Statement on Schedule 13D with respect to the persons
listed in Annex A.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

     (a) According to the latest Proxy Statement of the Fund filed with the
Commission on Form DEF 14A on April 8, 2005, there were 16,777,298 shares of
Common Stock outstanding at March 10, 2005. The percentage set forth in this
Item 5(a) was derived using such number. The Bank is the beneficial owner of
4,812,650 shares of Common Stock, which constitute approximately 28.68% of the
outstanding shares of Common Stock.

     (b) The Bank has sole power to vote and to dispose of the shares of Common
Stock owned by it.

     (c) During the last sixty days, the Bank has effected the following sales
in the shares of Common Stock in reliance upon Rule 144 under the Securities Act
