Campaign co-organiser Amanda Aldous said the aim of the adverts was to get constituents to contact the offices of federal politicians such as Riverina MP Michael McCormack and urge them to support integrity watchdog legislation from independent MP Helen Haines.

"There's been the recent corruption scandal with the [former] state member, so we would think the [Wagga] community is sensitive to the issue of integrity," Ms Aldous said.

"Our motivation is to get more community members to put pressure on the local members to stand up and support a robust bill.

"We think the bill put forward by our member, Dr Haines, has got teeth and the government's hasn't."

Ms Aldous said the system of oversight for integrity in federal politics "has to be more robust" whether it came in the form of Dr Haine's federal integrity commission proposal or another piece of legislation.

"The government can't ignore people forever; 80 per cent of Australians want this" she said.

An open letter with 417 signatories from Indi will run with the tagline 'Australia Needs A Robust Federal Integrity Commission Now'.

A campaign statement said the adverts across NSW newspapers were "entirely funded by donations from 247 individuals, who gave from as little as $10 each". and "no money was requested nor received from lobbyists, companies, unions or vested interests".

Attorney-General Christian Porter earlier this month announced legislation for a Commonwealth Integrity Commission (CIC), which he described as a "powerful new public sector watchdog".

"Australians rightly expect that those working in the public sector - including politicians and their staff - are held to the highest standards of honesty and accountability, which is why the new CIC has been given the most significant powers and resources to detect and deter criminal activity and enhance the public sector's long-term resilience," Mr Porter said.

The CIC model has been criticised by legal and police associations and policy think tanks as being too soft on MPs and Ministers, who would have allegations against them tested in private hearings.

Dr Haines, from the northern Victorian electorate of Indi, has said her alternate model for an integrity commission had "a common set of rules for everyone, whether you're a Member of Parliament or a staffer or departmental head" and would require public hearings.
