LATEST COVID-19 DEVELOPMENTS:
* An emergency meeting of Australia's national security committee will consider the increasing number of COVID-19 lockdowns.
* Federal Health Minister Greg Hunt concedes times are challenging, with NSW reporting 30 new cases on Sunday, Darwin sent into immediate lockdown and South Australia and Western Australia re-imposing restrictions.
* Total cases have ballooned to 110 in NSW after Greater Sydney and other areas entered into a 14-day lockdown.
* Darwin and its surrounds have entered a 48-hour shutdown following five new virus cases linked to a central Australian mine.
* None were locally transmitted but Chief Minister Michael Gunner says the outbreak represents the Northern Territory's biggest crisis since the beginning of the pandemic.
* One of the cases has turned up in NSW after 900 miners left the Tanami Desert site without knowing a co-worker had tested positive to the virus.
* Another is in quarantine after flying back to Darwin, two remain at the mine but will be transferred to Howard Springs, and the last is a close contact of one of the mine workers, who is now at Howard Springs.
* NT Chief Minister Michael Gunner said on Sunday 15 people who returned to the Darwin area were still to be accounted for, which was of major concern.
* The new NSW cases bring its outbreak to 110, while a further two local cases remain under investigation. More than 52,000 people were tested in the state and 12,881 received a vaccine dose in the 24 hours to 8pm on Saturday.
* Despite the jump in cases, NSW health chief Kerry Chant says they are all linked and if people take restrictions seriously and testing numbers are maintained, two weeks will be sufficient to get things under control.
* A Perth woman who visited Bondi in Sydney earlier this month and returned home has picked up the virus, prompting increased restrictions in WA. It's assumed she has the Delta virus variant.
* Residents of WA's Perth and Peel regions are now required to wear masks while indoors and on public transport. New arrivals to WA from Queensland, the ACT and Northern Territory must now get tested and self-isolate for 14 days.
* The major banks have announced extended support packages for small business and deferrals and fee refunds and waivers for home loan customers impacted by Sydney's lockdown.
