The Independent Commission Against Corruption (ICAC) will conduct a public inquiry of SafeWorkSA after a number of complaints about the regulatory body were reported.

"Since my office commenced in September 2013, the Office for Public Integrity has received a number of complaints and reports about SafeWork SA," said the Independent Commission Against Corruption, Bruce Lander, as quoted by the ABC.  "Each complaint and report has been dealt with on its merits.  Some resulted in no further action being taken.

"Others resulted in investigations undertaken by me (including the investigation I announced last week), or by the Chief Executive of the Attorney-General's Department, on referral from me."

One of the complaints about SafeWork SA was its decision to drop charges in show ride accident that killed a little girl in 2014.  Adelene Leong from Malaysia was thrown from the Airmaxx 360 ride at the Royal Adelaide Show; the eight-year old died in hospital.  SafeWork SA initially prosecuted the safety company that inspected the ride, Safe is Safe Pty Ltd, and its boss Hamish Munro.  But the agency dropped the case and withdrew charges.

SafeWork SA said it welcomes the inquiry. 

"Significant reforms are already underway, and this evaluation will give us the opportunity to evaluate the progress that has been made to date and identify where more work needs to be done," said SafeWork SA Executive Director Martyn Campbell.
