The recent suicide at Villawood Detention Centre in Sydney again confirmed that the situation in Australia’s immigration detention centres has become critical. But what has remained largely unquestioned is the role of Serco, the British multinational that holds the $367 million contract to run detention facilities across the country (alongside a few prisons and a just won contract for a hospital in Western Australia).

The company said it was "preparing a report" on the suicide for the Department of Immigration and Citizenship just after the event and most journalists left it at that. But Crikey has taken a closer look at the extent that Serco outsources to other companies.
