Doctors are prepared to demand digital health record laws are changed to ensure patients' medical records aren't handed over to police without a warrant.
Labor leader Bill Shorten also wants the My Health Record rollout suspended until privacy concerns are dealt with.
Australian Medical Association president Tony Bartone said he'll do "whatever it takes" to ensure patients keep the same legal rights as they have now.
When asked if that meant changing the legislation, Dr Bartone said: "Whatever it takes."
"I'll be having a conversation with the minister and if it means we have to go to that, that's where we'll go," he told the National Press Club on Wednesday.
Thousands of people have opted out of the scheme amid concerns data won't be secure, while the laws also allow for police to access the data without a warrant.
Mr Shorten said he wasn't giving up on the health record, but a suspension would help allay concerns.
"I actually think that it would be smart of the government to suspend the rollout of the My Health Record system until all of the privacy concerns are actually addressed," Mr Shorten told reporters in Brisbane.
Dr Bartone is set to meet with Health Minister Greg Hunt soon to get more assurances doctors will not breach privacy obligations because digital records aren't secure.
Mr Hunt insists that even though the laws allow police to access people's data without a warrant, it hasn't actually happened because the Digital Health Agency's policies override the law.
"The only people who can access your health record are those who have a link to you as a treating clinician or medical doctor, or other medical person," Mr Hunt told ABC radio.
"There will not be any document ever released without a court order.
"So that will remain the position, I think, forever."
Mr Hunt said the scheme had been operating for six years without a data breach.
