All prisons in the country will now be assessed, following the prison break of 68 inmates from the Malmesbury Remand Detention Facility.
Authorities say overcrowding and security measures will be scrutinised.
The 68 men escaped on Friday during an exercise routine when they overpowered 20 officials.
But with the help of the police, prison staff, private security and the local community, the inmates were back behind bars within 76 hours.
The breakout has exposed a flaw in the system which now needs to be identified.
