It may be a squabble over a paltry $6, but the stakes are high.
Speculation that the federal government wants to introduce a mandatory $6 GP fee is fast becoming a major issue in the by-election for the seat vacated by ex-Prime Minister Kevin Rudd.
The Greens have joined Labor in campaigning against the $6 GP fee in the Griffith electorate, trying to get residents to vote against the Liberal National Party at the February 8 poll.
An army of Greens voters are doorknocking homes in the electorate on Saturday, urging constituents to put LNP candidate Dr Glasson last on their ballot papers.
They say Dr Glasson, a former Australian Medical Association (AMA) president, supports plans to make patients pay a $6 fee every time they visit their GP.
Greens candidate for Griffith Geoff Ebbs says struggling residents would simply not be able to afford the charge.
"The people of Griffith will be queuing up at our local hospitals emergency departments to avoid paying this extra cost," Greens candidate for Griffith Geoff Ebbs said.
"More expensive medical expertise will be taken up for illnesses that GPs should be tending to."
The Doctors Reform Society of Australia is rallying with the Greens, while Labor has already come out firing on the $6 GP fee.
Opposition leader Bill Shorten was in Griffith on Thursday with Labor candidate Terri Butler to meet voters and campaign against Medicare co-payments.
However, the coalition maintains it has not considered or proposed to introduce a co-payment.
The government says the proposals were made by the Australian Centre for Health Research in a paper released publicly last October and have been the subject of media speculation since.
Dr Glasson says he has always been a passionate supporter of Medicare.
