Less than a day after announcing new Covid guidelines, the federal government has scrapped the need for infected people to take a day-six rapid test.
On Friday the government announced positive cases - regardless of vaccination status - will be able to leave isolation seven days after their positive test.
They will now not need to take a rapid test on day six to leave isolation.
But if a positive case still has symptoms on day seven, they should remain in isolation.
Health industry groups are questioning the decision not to provide rapid antigen tests free, or at least heavily subsidised, to Australians.
Following national cabinet on Thursday, Prime Minister Scott Morrison announced changes to Covid-19 isolation periods, a new definition of a close contact, and a greater reliance on rapid antigen tests instead of PCR tests.
Australians in NSW, Victoria, Queensland, and the ACT now only need to isolate for seven days if they are a close contact, defined as a household or intimate contact who has spent more than four hours with a positive case.
SA Premier Steven Marshall flagged the state would not be following the new definition.
'You're on your own': Labor slams Morrison
Federal Labor's health spokesman Mark Butler on Friday said the decisions from national cabinet were already falling apart.
"Scott Morrison has decided to let it rip without giving Australians the tools that they need to keep themselves safe and healthy, particularly booster shots and rapid tests," he said.
"The message to the Australian people yesterday from Scott Morrison essentially was, 'you're on your own'."
State testing centres will hand out rapid antigen tests over the coming weeks, but RATs will not be provided for free across the board, the prime minister said.
"Rapid antigen tests will be provided publicly at those testing centres for those who require one according to the rules," Mr Morrison said.
"For all other casual uses, that is what the private market is for."
Mr Morrison said private industry could purchase RAT supplies "and not have any concern that somehow a new policy will come in and tests will be be handed out to anybody who wants one".
The prime minister on Thursday said private providers had urged him not to make them free for Australians, but suppliers have denied Mr Morrison's claims.
Dean Whiting, chief executive of industry body Pathology Technology Australia, whose members provide about 95 per cent of all PCR tests and 70 per cent of RATs, says he never heard from the federal government.
The group has been calling for subsidised RATs for small to medium enterprises for months to help keep businesses open and limit the spread of Covid-19.
Mr Whiting said that while having certainty was welcome, not having at least a subsidised scheme was "counter to the best healthcare interests of Australia".
"My main concern is for people who can least afford that to do the testing," he told AAP.
"We do need a hybrid model where people who can afford to pay for the test should but those who can't should be able to get them for free, and that would be through the Commonwealth-funded pharmaceutical benefit schedule."
Pharmacy Guild of Australia president Trent Twomey told AAP "rapid antigen tests need to be universally accessible to all Australians".
The current situation of mass vaccination and testing hubs was not a long-term solution to the pandemic and the Guild has consistently called for a hybrid model so the "worried well" could take precautions "but it also enables those people who are complying with a state or territory public health order or those people on a healthcare or concession card (who) can access them for free."
The Australian Medical Association expressed its concern at the new arrangements, saying the amended definition of a close contact appeared to "put politics over health".
AMA President Dr Omar Khorshid said more cases would be missed with the narrowed definition, which could accelerate the outbreak.
"It seems national cabinet is prepared to bet that a massive Omicron outbreak won't cause large numbers of hospitalisations."
