Changes to contentious Vic health bill but no opt-out

While welcoming improved protections, Liberty Victoria president Michael Stanton said the amendments don't remedy the bill's foundational problem of not having an opt-out mechanism.

"We understand the desirability of health information sharing for medical professionals, but the bill fails to give due weight to the right to privacy and patient autonomy," he told AAP.

"Given previous data breaches and the sensitivity of some of this deeply personal information, people should have the right to decide whether they want to be part of the scheme."
