Coronavirus: Scott Morrison, national cabinet to discuss fallout of new decision on AstraZeneca vaccine for over-60s

State and territory leaders weren't set to meet again until next month in Darwin, but the meeting was called following the federal government decision to limit the use of the AstraZeneca vaccine to people aged above 60.

The decision has placed extra pressure on supplies of the Pfizer vaccine, which is now the only vaccine available to people below 60.

On Sunday Labor's health spokesman Mark Butler said Australia should have signed more deals for a wider range of vaccines earlier in the pandemic.

"We are really only left now with Pfizer for a broad population vaccine, which is only coming in at about 350,000 doses per week," he said on Sky News.

The Moderna vaccine, which uses cutting-edge mRNA technology like the Pfizer vaccine, is still to be approved in Australia, but the government has signed a deal for 25 million doses with delivery of 10 million expected later this year.

Mr Butler said if a deal had been signed earlier, that vaccine could fill the hole in the current rollout.

"It is running in dozens of countries around the world - a highly effective vaccine. But we won't see it until very late this year, we should be substituting it by now for AstraZeneca, which is what other countries around the world have been able to do."

The Senate committee inquiring into Australia's ongoing response to the COVID-19 pandemic will on Monday night interrogate Australia's top health advisers to get the story behind Thursday's announcement on AstraZeneca.

ACT Chief Minister Andrew Barr said the ACT has managed to secure an extra 1500 doses of the Pfizer vaccine per week over the coming weeks. There is hope the extra doses will help in ACT Health's bid to reschedule 2700 appointments of people aged 50-59 who were booked to get the AstraZeneca vaccine.

Last week ACT Health authorities asked people aged 50-59 not to call and try to book a new appointment due to the workload associated with rebooking appointments with limited supply.

"Early next week we will have further information available to 50-59 yr olds, including how you can book for a Pfizer appointment, where you can receive your vaccine and what you need to do," Mr Barr tweeted.

"We will provide updates on the COVID-19 website and through our social media channels."

Meanwhile, NSW has recorded three new locally acquired COVID-19 cases as some Sydneysiders were ordered to don masks indoors amid the city's growing outbreak.

Two new local cases were reported in the 24 hours to 8pm on Sunday, one of which had been revealed by health authorities on Saturday. The other case is a close contact of the previously recorded case.

But NSW Health said on Sunday that two additional cases in the Sutherland Shire in southern Sydney were recorded after the 8pm deadline. They were both close contacts of previously reported cases.

It takes Sydney's eastern suburbs outbreak to nine cases.

The growing Bondi cluster has prompted new mask-wearing rules, announced by NSW Premier Gladys Berejiklian on Sunday.

Anyone shopping, working in hospitality or indoors must wear a mask unless eating or drinking if they live in the local government areas of Randwick, Bayside, Botany Bay, Inner West, City of Sydney, Waverley or Woollahra.

Ms Berejiklian said the government would also extend compulsory mask-wearing on public transport in Greater Sydney until Thursday. This restriction will also be extended for Wollongong and Shellharbour local government areas.

Meanwhile, a flight attendant has tested positive for coronavirus in Brisbane despite undergoing the full 14 days of hotel quarantine.

The woman aged in her 30s arrived in Brisbane on June 5, on an Emirates flight that also transported a passenger with the more infectious Delta strain, although test results have not yet confirmed the attendant has the Delta strain.

An outbreak of the Delta variant, which is the dominant strain in India and the UK, recently led to a statewide lockdown in Victoria.

The Queensland government has listed exposure sites including Brisbane's airport DFO, the Brisbane CBD and a Portuguese family centre which the woman visited on Saturday.

The new case comes as Queensland prepares to ease its virus restrictions on Friday, allowing more people to visit restaurants, cafes and bars, and more people allowed on reef charter boats.

In Victoria, no new local cases were reported on Sunday but two possible "historical" infections from released returned travellers are under investigation.

State Health Minister Martin Foley said the pair had produced conflicting results on different testing platforms, with an expert panel convened to review their infections.

The Victorian government has announced a locally developed mRNA vaccine will become the first in Australia to move to phase one clinical trials later this year.

The Monash Institute of Pharmaceutical Sciences-led vaccine has received a $5 investment to manufacture doses for the trials, with results expected in the first half of 2022.

Commonwealth officials earlier this month told Senate estimates it could take up to four years to build a site to start manufacturing mRNA vaccines like the Pfizer and Moderna jabs.

Acting Premier James Merlino said Victoria had taken a "leadership position" on research and development to ensure the nation doesn't rely on overseas supply, which has crippled the vaccine rollout.

"This virus will be with us for quite some time. We may well need yearly booster vaccines in the years ahead," he said.

South Australia on Sunday joined Queensland and imposed an immediate ban on travellers who have been in Sydney's Waverley Council area.

South Australian residents or anyone escaping domestic violence can enter, but will still need to self-quarantine for a fortnight.

The West Australian government will set up COVID-19 testing clinics at Perth Airport's domestic terminals from Sunday to enforce new conditions imposed on travellers from NSW.

All arrivals from NSW must get a test on arrival or within 48 hours and self-quarantine until they return a negative result.
