Timberland Bancorp, Inc. Announces Increased Second Quarter Earnings
                      *  Net Income Increases by 34%
                      *  Diluted Earnings Per Share Increases by 33%
                      *  Return on Equity Increases by 28%
                      *  Net Interest Margin Increases by 7%

HOQUIAM, Wash.   April 25, 2006   Timberland Bancorp, Inc. (NASDAQ: TSBK),
("Company") the holding company for Timberland Bank, ("Bank"), today reported
net income of $1.95 million, or $0.53 per diluted share, for the quarter ended
March 31, 2006.  This compares to net income of $1.45 million, or $0.40 per
diluted share that the Company earned for the quarter ended March 31, 2005.
The increased earnings per share was primarily a result of increased net
interest income and increased non-interest income.

"The solid results for the second fiscal quarter are largely the result of the
Company's focus on balancing the repricing characteristics of its assets and
liabilities.  This has allowed the maintenance of a healthy net interest
margin in spite of the current flat yield curve environment.  As compared to
the same period in the prior fiscal year, net income, diluted earnings per
share and return on equity have increased by 34%, 33% and 28% respectively,"
stated Michael Sand, Timberland's President and CEO.  "Our focus during the
remainder of the year will be the profitable growth of the Company,"
Sand also stated.

The Company recently announced the addition of Robert Drugge as a Senior Vice
President in the Bank's Business Banking Division.  Bob was hired to oversee
the Bank's expanding business banking presence in Pierce, Kitsap and southern
King counties.  He brings nearly 20 years of in-market experience most
recently managing relationships with companies having sales of between $10
million and $2 billion.  Bob's lending and management expertise have been
shaped by his career affiliation with Seafirst and its successor, the Bank of
America.  "We are looking forward to the contributions that Bob will make in
furthering the goals of Timberland Bancorp, Inc.," Sand further stated.

Comparison of Financial Condition at March 31, 2006 and September 30, 2005

Total Assets: Total assets increased $4.61 million to $557.38 million at March
31, 2006 from $552.77 million at September 30, 2005 primarily due to a $5.13
million increase in net loans receivable and $2.57 million increase in cash
and due from financial institutions.   These increases were partially offset
by a $2.95 million decrease in investment securities.

Investments:  Investment securities decreased by $2.95 million to $92.45
million at March 31, 2006 from $95.40 million at September 30, 2005, due to
regular amortization and prepayments on mortgage-backed securities.

Loans: Net loans receivable increased by $5.13 million to $393.24 million at
March 31, 2006 from $388.11 million at September 30, 2005.  The increase in
the portfolio was primarily a result of a $6.38 million increase in
construction loans (net of undisbursed portion), a $3.33 million increase in
land loans, a $2.75 million increase in consumer loans, and a $1.89 million
increase in multi-family loans.  Partially offsetting these increases were
decreases of $5.46 million in one-to-four family mortgage loans, $2.58 million
in commercial business loans, and $1.37 million in commercial real estate
loans.

Loan demand remains relatively strong in the Bank's market areas, although an
unusually wet winter impacted the loan portfolio by delaying construction loan
disbursements on existing construction loans and kept some of the Bank's
builders from beginning new projects.  Undisbursed construction loan balances
increased by $10.10 million to $52.87 million at March 31, 2006.   Loan
originations totaled $43.98 million and $109.76 million for the three and six
months ended March 31, 2006 compared to $48.94 million and $110.38 million for
the three and six months ended March 31, 2005.  The Bank also continued to
sell longer-term fixed rate loans for asset liability management purposes.
The Bank sold fixed rate one-to-four family mortgage loans totaling $5.52
million and $13.05 million for the three and six months ended March 31, 2006
compared to $4.63 million and $7.96 million for the three and six months ended
March 31, 2005.

Deposits: Deposits increased by $2.37 million to $414.04 million at March 31,
2006 from $411.67 million at September 30, 2005.  The deposit increase was
primarily due to a $12.2 million increase in certificate of deposit accounts.
This increase was partially offset by decreases of $7.33 million in money
market accounts, $1.38 million in savings accounts, and $1.12 million in
non-interest bearing accounts.

Shareholders' Equity: Total shareholders' equity increased by $3.07 million to
$77.71 million at March 31, 2006 from $74.64 million at September 30, 2005,
primarily due to net income of $3.95 million and a $544,000 increase to
additional paid in capital from the exercise of stock options and vesting
associated with the Company's benefit plans.  Also increasing shareholders'
equity was a decrease of $264,000 in the equity component related to unearned
shares issued to the Employee Stock Ownership Plan.  Partially offsetting
these increases to shareholders' equity were the payment of $1.20 million in
dividends to shareholders, the repurchase of 8,200 shares of the Company's
stock for $193,000, and a $292,000 increase in accumulated other comprehensive
loss.

On April 7, 2005, the Company announced a plan to repurchase up to 5% of the
Company's outstanding shares, or 187,955 shares.  This represents the
Company's 13th stock repurchase plan.  As of March 31, 2006, the Company had
repurchased 36,050 of these shares at an average price of $23.26.
Cumulatively the Company has repurchased 3,375,321 (51.0%) of the 6,612,500
shares that were issued when the Company went public in January 1998.  The
3,375,321 shares have been repurchased at an average price of $15.41 per
share.


Comparison of Operating Results for the Three and Six Months Ended March 31,
2006 and 2005

Net Income: Net income for the quarter ended March 31, 2006 increased to $1.95
million, or $0.53 per diluted share ($0.55 per basic share) from $1.45
million, or $0.40 per diluted share ($0.42 per basic share) for the quarter
ended March 31, 2005.  The $0.13 increase in diluted earnings per share for
the quarter ended March 31, 2006 was primarily a result of a $656,000
($433,000 net of income tax - $0.11 per diluted share) increase in net
interest income after provision for loan losses and a $169,000 ($112,000 net
of income tax - $0.03 per diluted share) increase in non-interest income.
These


                                         5





items were partially offset by a $48,000 ($32,000 net of income tax - $0.01
per diluted share) increase in non-interest expense.

Net income for the six months ended March 31, 2006 increased to $3.95 million,
or $1.09 per diluted share ($1.13 per basic share) from $2.95 million, or
$0.80 per diluted share ($0.84 per basic share) for the six months ended March
31, 2005.  The $0.29 increase in diluted earnings per share for the six months
ended March 31, 2006 was primarily the result of a $1.31 million ($867,000 net
of income tax - $0.24 per diluted share) increase in net interest income after
provision for loan losses, a $186,000 ($123,000 net of income tax - $0.03 per
diluted share) increase in non-interest income, a $76,000 ($50,000 net of
income tax - $0.01 per diluted share) decrease in non-interest expense, and a
lower number of weighted average shares outstanding, which increased diluted
earnings per share by approximately $0.01.

Net Interest Income: Net interest income increased $636,000 to $6.06 million
for the quarter ended March 31, 2006 from $5.43 million for the quarter ended
March 31, 2005, primarily due to a larger interest earning asset base and an
increase in the Company's net interest margin.  Total interest income
increased $1.22 million to $8.65 million for the quarter ended March 31, 2006
from $7.43 million for the quarter ended March 31, 2005 as average total
interest earning assets increased by $22.89 million.  The yield on interest
earning assets increased to 6.91% for the quarter ended March 31, 2006 from
6.22% for the quarter ended March 31, 2005.  Total interest expense increased
by $583,000 to $2.59 million for the quarter ended March 31, 2006 from $2.00
million for the quarter ended March 31, 2005 as average interest bearing
liabilities increased $11.65 million.  The average rate paid on interest
bearing liabilities increased to 2.47% for the quarter ended March 31, 2006
from 1.94% for the quarter ended March 31, 2005.  The net interest margin
increased to 4.84% for the quarter ended March 31, 2006 from 4.56% for the
quarter ended March 31, 2005.

Net interest income increased $1.29 million to $12.09 million for the six
months ended March 31, 2006 from $10.80 million for the six months ended March
31, 2005, primarily due to a larger interest earning asset base and an
increase in the Company's net interest margin.  Total interest income
increased $2.36 million to $17.09 million for the six months ended March 31,
2006 from $14.73 million for the six months ended March 31, 2005 as average
total interest earning assets increased by $24.30 million.  The yield on
interest earning assets was 6.87% for the six months ended March 31, 2006
compared to 6.22% for the six months ended March 31, 2005.  Total interest
expense increased by $1.07 million to $5.01 million for the six months ended
March 31, 2006 from $3.94 million for the six months ended March 31, 2005 as
average interest bearing liabilities increased $13.53 million.  The average
rate paid on interest bearing liabilities increased to 2.38% for the six
months ended March 31, 2006 from 1.94% for the six months ended March 31,
2005.  The net interest margin increased to 4.85% for the six months ended
March 31, 2006 from 4.54% for the six months ended March 31, 2005.

Provision for Loan Losses:  There was no provision for loan losses made during
the six months ended March 31, 2006 as credit quality remained strong. The
allowance for loan losses, however, did increase during this period due to a
net recovery of $20,000.  Based on its comprehensive analysis, management
deemed the allowance for loan losses of $4.12 million at March 31, 2006 (1.04%
of loans receivable and 201.91% of non-performing loans) adequate to provide
for probable losses based on an evaluation of known and inherent risks in the
loan portfolio at that date.  The allowance for loan losses was $4.01 million
(1.05% of loans receivable and 130.99% of non-performing loans) at March 31,
2005.  The Company had net recoveries of $2,000 and $20,000 for the three and
six months ended March 31, 2006 compared to net charge-offs of $7,000 and
$4,000 for the three and six months ended March 31, 2005.

The Company's non-performing assets to total assets ratio decreased to 0.39%
at March 31, 2006 from 0.52% at December 31, 2005 and 0.64% at March 31, 2005.
The non-performing loan total of $2.04 million at March 31, 2006 consisted of
a $1.36 million commercial construction loan, $506,000 in one-to-four family
mortgage loans, and a $179,000 commercial real estate loan.

Non-interest Income: Total non-interest income increased $169,000 to $1.51
million for the quarter ended March 31, 2006 from $1.34 million for the
quarter ended March 31, 2005, primarily due to $95,000 increase in service
charges on deposits, a $29,000 increase in servicing income on loans sold, and
a $27,000 increase in ATM transaction fees.  The Bank also continued to
generate non-interest income from the sale of fixed-rate loans.  During the
quarter ended March

                                         6




31, 2006, the Bank sold $5.52 million in fixed rate one-to-four family
mortgages for a gain of $88,000 compared to sales of $4.63 million for a gain
of $84,000 for the quarter ended March 31, 2005.

Total non-interest income increased by $186,000 to $3.06 million for the six
months ended March 31, 2006 from $2.88 million for the six months ended March
31, 2005, primarily due to a $179,000 increase in fees from the sale of non-
deposit investment products, a $118,000 increase in service charges on
deposits, and a $98,000 increase in servicing income on loans sold.   These
increases were partially offset by a $228,000 decrease in gains from loan
sales.  Income from loan sales was larger in the period a year ago due to the
sale of the Bank's credit card portfolio in December 2004, which resulted in a
gain of $245,000.

Non-interest Expense: Total non-interest expense increased by $48,000 to $4.72
million for the quarter ended March 31, 2006 from $4.67 million for the
quarter ended March 31, 2005.  The increase was primarily a result of
increases in salary expense, premises and equipment expense, and state and
local tax expense.  These increases were partially offset by decreases in
advertising expense, real estate owned operation expense, and postage and
courier expense

Total non-interest expense decreased by $76,000 to $9.36 million for the six
months ended March 31, 2006 from $9.43 million for the six months ended March
31, 2005.  Non-interest expenses were higher a year ago primarily due to
expenses of $183,000 related to the branch acquisition in October 2004 and
vesting expenses of $335,000 related to one of the Company's benefit plans.
Partially offsetting these expense decreases during the current year, were
increases in expenses related to salaries, premises and equipment, and state
and local taxes.   The Company also began expensing stock options under SFAS
123(R), which became effective for the Company on October 1, 2005.  Total
stock option expenses of $11,000 were recorded for the six months ended March
31, 2006.   As a result of the decreased expenses and increased revenue, the
Company's efficiency ratio improved to 61.74% for the six months ended March
31, 2006 from 68.98% for the six months ended March 31, 2005.
