Australian Auditor General Grant Hehir will resign next month after 15 years of scrutinising government departments, agencies and programs.

PM&C secretary Glyn Davis said Mr Hehir had provided a significant service to the APS and made a sustained contribution to integrity in public administration.

“I have had the pleasure of working with Mr Hehir for many years, in both his current and previous roles, and greatly value his advice and expertise,” Mr Davis said in a statement.

Mr Hehir previously served as NSW Auditor-General and held senior roles in the Victorian State Government, including as Secretary of the Department of Treasury and Finance and the Department of Education and Training.

He has also worked in senior executive roles at the Commonwealth Department of Finance.

Mr Hehir leaves his post on February 15.
