In June 2009, DIAC entered into a five-year contract with Serco to provide services in detention centres across Australia. The transition from previous provider G4S to Serco was completed nearly one year ago.
Serco also has a contract with the department to provide services for people in immigration residential housing and transitional accommodation.
DIAC says it has implemented performance standards as part of its contracts with detention centre service providers. Part of the performance standards will focus on the well-being of people in detention.
