“If GPs don't feel confident in the system, we will protect our patients' privacy,” Dr Phelps said.

Dr Phelps is particularly concerned by Section 98 of the My Health Record Act, which gives the "system operator" - currently the Australian Digital Health Agency - the power to delegate "any function" to “any other person” with consent of the minister.

"This could include the disclosure of your health information," Dr Phelps said.

And she said the fact that nine data breaches had been recorded showed the system could not be trusted to keep people's data safe.

Mr Hunt has denied reports in the Daily Telegraph – based on publicly available Annual Reports from the Office of the Information Commissioner – that the My Health Records system has had nine data breaches in two years.

The Australian Digital Health Agency said in a statement that the breaches did not relate to unauthorised viewing of any individual’s health information but were alleged fraudulent Medicare claims or administrative processing errors.

The minister has promised to ensure that any third party access to medical records, which under the current legislation can be granted to authorities including police, courts and the Australian Taxation Office, may only be granted with a court order.

But Dr Phelps said this was not enough.

Mr Hunt announced plans to tweak the My Health Record Act on Tuesday night after meeting with AMA president Tony Bartone and Royal Australian College of General Practitioners president Harry Nespolon.

The minister also pledged to ensure that any Australian who wished to delete their My Health Record could do so permanently.

But while the leaders of both peak medical bodies welcomed the announcement as a victory for patient welfare, the profession remains fiercely divided.

Dr Phelps told Fairfax Media that the medical and general practicioners associations “appear to be out of line with the sentiments in the medical profession”, after a survey by industry publication Australian Doctor found that three-quarters of doctors planned to opt-out themselves.

Dr Bartone said Dr Phelps' call for a review was “premature”, saying the government had committed to amending the legislation “to cover off privacy concerns about the My Health Record”.

“The AMA believes we should see the government’s changes and safeguards first, and judge them accordingly,” he said.

“The Parliament will then have the chance to pass or reject the amended legislation, which is effectively a full Parliamentary review.”

Any legislative review would be subject to intense political debate, with divisions in the Coalition after Liberal MP Tim Wilson revealed that he was opting out.

“I would be very surprised if there weren't a number of Liberals who were prepared to cross the floor on this,” Dr Phelps said.

One Nation leader Pauline Hanson has also spoken out against My Health Record, giving her supporters detailed instructions on how to opt out.

Mr Hunt secured the support of his state counterparts at a meeting of state and territory health ministers in Alice Springs on Thursday, after the Queensland Labor government threatened to disrupt the roll-out of the digital health records system.

But the federal opposition wants the My Health Record system to be suspended until GP and patient concerns are adequately addressed.

“We don't believe that anything less than a suspension of the opt-out of the My Health Record, whilst the government rebuilds community trust in the My Health Record, will be sufficient,” opposition health spokeswoman Catherine King said on Wednesday.
