As government data from November showed a 2.1 percentage point rise in the national GP bulk billing rate, a Productivity Commission report revealed the number of people delaying an appointment or not attending at all due to price had doubled.

In 2022/23, seven per cent of respondents who needed to see a GP did not visit due to cost, compared with 3.5 per cent the previous year.

In NSW alone, the number of people putting off visits to the doctor rose from 4.4 per cent in 2021/22 to 9.5 per cent in 2022/23.

It comes despite a national rise in the number of GP clinics offering bulk billing to patients, with an extra 360,000 appointments bulk billed since November, when the incentive for doctors to offer the subsidised visits tripled.

The figures, released by the federal government on Thursday coinciding with the 40th anniversary of Medicare, showed $15 million had been saved in gap fees since the tripling of the bulk billing initiatives.

GPs have received triple the benefits to bulk bill patients on concession cards and children under 16, with further financial incentives for clinics in regional areas.

Health Minister Mark Butler said the extra financial incentives were making a difference for clinics and patients.

“The Albanese government committed to making it easier for people to see a bulk billing doctor, and the first two months of data show that is exactly what is happening right around the country, particularly in rural and regional areas,” he said.

“At the same time, general practice incomes have increased.

“This is a win all round, for patients, doctors and the health system, and it is helping to make Medicare stronger than it has ever been since Labor introduced it 40 years ago.”

The number of GP clinics offering bulk billing had increased in every state and territory with Tasmania recording the greatest increase of 5.7 percentage points, followed by South Australia with 3.8 percentage points.

NSW still leads for the number of clinics offering bulk billing with 82.3 per cent, followed by 78.3 per cent of GPs in Victoria and 75.8 per cent in Queensland.

The ACT had Australia’s lowest rate for subsidised GP visits, with just 53.4 per cent of clinics in the nation’s capital offering bulk billing.

The Royal Australian College of General Practitioners said the 2.1 per cent increase in bulk billing for vulnerable patients nationally was evidence that boosting Medicare subsidies gets results.

“We called last year’s budget a gamechanger because it was the biggest investment in general practice care in decades. And funding gets results,” college president Nicole Higgins said on Thursday.

“There is still a long way to go to repair the decades of cuts and neglect.”

Prime Minister Anthony Albanese hailed the 40th anniversary of Medicare, an initiative of the Hawke Labor government, noting it processes almost half a billion services a year, with most claims made on the spot at the doctor’s.

“Every day, everywhere I go, people talk to me about healthcare and how important it is to their lives,” he said in a statement.

“We are so lucky to have a system like Medicare in this country and we owe a great debt to people like Gough Whitlam and Bob Hawke who fought so hard to deliver it.”

Commemorative Medicare card are being rolled out from Thursday to mark the milestone anniversary for people who get a new or replacement card between February 1 and December 31.
