The lives of detainees in Australia’s immigration detention centres are controlled by a secret rating system that is opaque and often riddled with errors, a Guardian investigation has found.
Developed by Serco, the company tasked with running Australia’s immigration detention network, the Security Risk Assessment Tool – or SRAT – is meant to determine whether someone is low, medium, high or extreme risk for factors such as escape or violence.
Detainees are also rated for an overall placement and escort risk – which may determine how they are treated while being transported, such as whether they are placed in handcuffs and where they stay inside a detention centre – but aren’t given the opportunity to challenge their rating, and typically are not even told it exists.
Immigration insiders, advocates and former detainees have told Guardian Australia the SRAT and similar algorithmic tools used in Australia’s immigration system are “abusive” and “unscientific”. Multiple government reports have found that assessments can be littered with inaccuracies – with devastating consequences.
