Corrective Services Commissioner James McMahon has revealed that only one of the van doors was shut properly in last month's escape of two prisoners. One of the parts on the internal lock did not click into the hole properly, which is believed to have assisted the pair in their escape.

Mr McMahon said main reason for the escape was that only the van’s inner door was shut. He said systematic testing was not done by Serco to the level it needed to be done.

Today the ABC revealed that Serco will spend about $300,000 to upgrade its entire fleet of 41 prisoner transport vans because a problem has been discovered with the locks on the interior doors.

Reports have also surfaced today that Serco will pay more than $700,000 over the escape of the two prisoners.
