The Morrison government has reignited concerns over state border closures as Australians grapple with inconsistent travel restrictions in different parts of the country.
There is no consistent approach one year into the pandemic with the latest outbreaks sparking snap closures of state and territory borders.
Health Minister Greg Hunt is urging governments to use the national hotspot definition to justify interstate travel restrictions.
"The risk is not of transmission from one state to another in any material or significant way," he told reporters on Tuesday.
He said taking the unrealistic step of closing all international borders was the only way to eliminate virus threat.
"No export of wheat, or wool, or iron ore. No import of critical foods or critical medicines. No families being reunited," Mr Hunt said.
There were six locally acquired coronavirus cases in Australia on Tuesday - five in NSW and one in Queensland - compared to 600,000 globally.
"That's where the point of challenge and risk is. That's why we have very strict, and in many cases, heart-wrenchingly difficult limitations on people coming to Australia," Mr Hunt said.
Acting Prime Minister Michael McCormack is concerned Victoria didn't consult the federal government on its new permit regime, which categorises all areas of Australia as either red, orange or green based on virus risk.
Greater Sydney remains classified as a red area for entry to Victoria, meaning it's not possible without completing two weeks of hotel quarantine.
But the Northern Territory and the ACT have relaxed rules for some parts of Greater Sydney.
Restrictions remain for people travelling to a handful of local government areas in Sydney, primarily in the northern beaches and in the city's west.
Mr Hunt is confident new virus strains won't put the brakes on rolling out vaccines, saying candidates will remain effective according to the latest advice.
General practitioners will next week be asked if they want to take part in the national coronavirus vaccination network.
GPs will be involved with the AstraZeneca vaccine once it gets the official stamp of approval from Australia's medical regulator, while hospitals will administer the Pfizer jab.
Mr Hunt confirmed the regulator hadn't yet reached a decision on whether pregnant women should have the vaccine.
A highly infectious strain of the virus found in the UK led to Brisbane's now finished three-day lockdown after a hotel quarantine cleaner caught it.
It also resulted in lower weekly caps on international arrivals with passenger numbers halved on three repatriation flights because of the lower limit.
Around 37,000 Australians stranded overseas have told DFAT they want to return.
