South Australia's Independent Commissioner Against Corruption (ICAC) Bruce Lander has asked the State Government for more money to run the office.

Mr Lander said his office had a budget of $35 million over four years but would need more funds to cope with referred matters.

"The original budget was formulated in 2012 without any knowledge of the extent of the work the office would generate," he said

The Commissioner said so far it had received about 1,100 complaints and internal reports.

Mr Lander said a case relating to a public officer had been referred to the Director of Public Prosecutions (DPP) to decide if charges should be laid.

He said several other investigations were underway, including one involving another public officer, and extra investigators had been needed to deal with that.

"We've employed former police officers to assist us in the taking of statements ... over a period of time, so we need further resources to investigate it properly," he said.

The Commissioner said he could not reveal details of the matter he referred to the DPP but confirmed it related to conduct of a public servant who was no longer employed by the Government.

"It's probable the public will hear more about it if and when a prosecution is launched and the matter goes before the court," he said.

Councils subject to complaints

Mr Lander expressed concern about the number of complaints that had been made about council-related matters.

"We've instigated a number of investigations utilising the ombudsman ... into the conduct of a number of council employees, which amounts not to corruption but misconduct," he said.

"I have volunteered to travel around the state to speak to council members about their responsibilities and their duties ... in an effort to reduce the number of complaints being made against them."

Local Government Association chief executive Wendy Campana said they embraced the establishment of the ICAC and the work Mr Lander had been doing with councils across the state.

"There are currently around 714 elected members and 10,000 employees in local government," Ms Campana said.

"Because we work so closely with the community it is bound to happen that people sometimes feel aggrieved about things they don't agree with.

"Also there are sometimes incidents between council members and the public, which can prompt a report to the Ombudsman or the ICAC.

The Commissioner said he felt confident after a year of operation there was no evidence of systemic corruption in South Australia.

"There's plenty of opportunistic corruption where individual officers behave inappropriately, but no evidence so far of systemic corruption."

Mr Lander said he had put a submission to Cabinet asking for more funding.

"We're adequately resourced at the moment, but in the forward estimates I think there may need to be further provision for further resources so as to ensure that the office can perform its functions appropriately," he said.

"We think over the next year we will need to increase the resources so as to deal with the number of complaints and reports that are made."
