New data confirmed that health costs have soared since 2012, Federal Member for Barton Linda Burney said.
"The Government's own Health Department has revealed to the Senate that people in the electorate of Barton, which includes the St George area, pay an average out-of-pocket fee of $36.35 to see a GP," Ms Burney said.
"This is a record high - up $10.78 or 42 per cent since the Liberals were elected," she said.
Figures released in response to questions by Senator Deborah O'Neill to the Senate Community Affairs Committee show:
Average out-of-pocket costs for GP non-referred attendances in the Barton electorate went from $25.57 in 2012-13 to $28.43 in 2013-14, increasing to $36.35 in 2018-19.
The average out-of-pocket cost for specialist attendances went from $66.17 in 2012-13 to $97.02 in 2018-19.
"Specialist out-of-pocket fees are at record highs, with people in Barton paying an average $97.02 to see a specialist, up a staggering $30.85 or 47 per cent since 2012-13," Ms Burney said.
"With just 29 per cent of people in Barton always bulk billed by specialists, these costs hit thousands of locals every year.
"Seeing a doctor and accessing health services in Barton has become more difficult under the Liberals."
Other figures show the bulk billing rate for GP non-referred attendances in the electorate of Barton has declined from 95.3 per cent in 2012-13 to 95 per cent in 2018-19.
The percentage of patients with all GP non-referred attendances bulk billed in Barton declined from 86.3 per cent in 2012-13 to 85.8 per cent in 2018-19.
Shadow Health Minister Chris Bowen described the introduction by the Government of the Medicare freeze as a "GP Tax-by-stealth".
"The Prime Minister extended the freeze as Treasurer, leading directly to the out-of-pocket costs that people in Barton face today," he said.
