Prime Minister Anthony Albanese has ruled out the possibility of bringing back COVID-19 restrictions and lockdowns, saying state premiers and chief ministers didn't demand them during the last national cabinet meeting.
Mr Albanese said it was up to employers to decide whether they want their workers to wear face masks at workplace or work from home.
Prime Minister Albanese told media in Melbourne that Chief Health Officer Paul Kelly has not recommended mandating masks rules.
Mr Kelly, however, has been urging Australians to wear face masks in crowded indoor settings. On Tuesday, Mr Kelly released a statement saying new COVID-19 cases will continue to rise in Australia over the coming month.
Professor Kelly said there could be a rise in the number of people dying with COVID-19, especially among those at higher risk of severe disease, people over 80 and those who have not received all recommended vaccine doses.
He urged employers to allow work from home.
There has been a three-fold rise in the uptake of the fourth vaccine dose.
Health authorities said almost 560,000 fourth doses were administered in the first week of expanded eligibility compared with nearly 180,000 the week before.
A peer-reviewed in the UK showed acute COVID-19 was associated with a six-fold increase in cardiovascular diagnoses and an 81 per cent increase in diabetes diagnoses.
Another peer-reviewed study published in the JAMA Network showed a slightly higher chance of an adverse reaction when COVID-19 booster doses and influenza vaccines are administered at the same time.
However, these reactions are mainly mild or moderate.
The Australian Technical Advisory Group on Immunisation said it doesn't specifically recommend a fourth vaccine dose for pregnant women aged 30 and over.
Such women should consult their doctors to review their health needs and the benefits and risks of the fourth dose.
