The Maribyrnong facility in Melbourne will close immediately after the last of the detainees there were moved to other centres on Monday.
, will close by May with the detainees also moved to the other seven centres.
There are 1250 people now in immigration detention in Australia. They are boat arrivals dating back to 2013 or earlier, people who have had their visas cancelled on character grounds and those who have overstayed their visas.
Immigration Minister David Coleman has called it "another milestone in the ramping-down of Australia's onshore immigration detention network".
He said in a statement Labor's "catastrophic" border policy had forced the Rudd and Gillard governments to open 17 immigration detention facilities.
About 1000 people remain in immigration detention in offshore processing centres on Nauru and Manus, some have been there since 2013. The Christmas Island camp has been closed.
"The government has stopped the boats, got the children out of detention and closed the once-full immigration detention facilities," Immigration Minister David Coleman announced in a statement.
