A prominent Oakden whistleblower who offered to work with the State Government and drive change says he is losing confidence in its commitment to real reform and fears ministers are only dealing in “damage control” to limit the political pain of embarrassing headlines. Stewart Johnston went public last month after the release of Chief Psychiatrist Aaron Groves’ scathing report, to detail abuse against his mother Helen at the site in 2008. He was one of several relatives of Oakden residents who met with Premier Jay Weatherill, and emerged offering the Government the benefit of the doubt amid its pledge of major change.
