South Australia's Auditor-General Simon O'Neill has been given a pay rise even though he specifically asked not to receive one.

The Government Gazette shows the Remuneration Tribunal has increased Mr O'Neill's salary by 2.5 per cent to almost $304,000.

Mr O'Neill previously told the Tribunal there was a need for continued salary constraint in the public service, because of the South Australia's tight budgetary conditions.

The 2.5 per cent pay rise also applied to several other top public service posts.

The state's Electoral Commissioner will now receive about $190,500 per year with the Deputy Commissioner to take home $138,500.

The Employee Ombudsman will receive $143,000 and the Health and Community Services Complaints Commissioner $224,000.
