Officers have regained control of the migrant detention center on Christmas Island, Australia's Immigration Department said Tuesday afternoon.
Five inmates were injured or had medical problems and were being treated by medical staff, the department said in a statement.
"The majority of detainees co-operated with service providers in restoring good order and control to the centre," it said.
"Some force was used with a core group of detainees who had built barricades and actively resisted attempts to secure compounds, including threatened use of weapons and improvised weapons."
The riot that began Sunday night had left some parts of the detention center severely damaged, the department said. Any offenders who can be identified will be prosecuted.
The riot at the immigration detention centre began after the body of an Iranian Kurdish man was found outside the centre's high fence after he escaped on Saturday.
There are 203 inmates currently at the centre, including many non-Australian criminals who have been removed from Australian prisons to the remote Indian Ocean island detention prior to being deported.
Immigration Minister Peter Dutton said it was these criminals who were at the core of the riot.
The government is facing questions in parliament why hardened criminals were put in the same detention centre as asylum seekers and people who had simply violated their visas.
