LATEST DEVELOPMENTS

* South Australia reported no new coronavirus cases as the state began a six-day hard lockdown.

* The Parafield cluster was revised down to 22 confirmed infections late on Thursday, but there are another 17 suspected cases.

* In an effort to "double ring fence" the outbreak, SA Chief Public Health Officer Nicola Spurrier said 3200 close contacts of known cases are in quarantine and thousands more self-isolating.

* SA Premier Steven Marshall insists the statewide shutdown is absolutely necessary to break the chains of transmission and prevent more widespread community infection.

* South Australia's police commissioner came to the defence of people working in coronavirus quarantine hotels, urging critics to "give these people a break".

* It came as it emerged the source of the cluster was a cleaner at an Adelaide medi-hotel who is thought to have picked up the virus from a surface and then infected members of her family.

* An inquiry into Victoria's medi-hotel regime recommended people not work across multiple environments. However, a hotel security guard in Adelaide had a second job at a pizza shop where authorities have grave concerns about transmission.

* All hotel quarantine workers around Australia will now be tested weekly, while international flights won't land in Adelaide until at least November 30.

* Prime Minister Scott Morrison believes no hotel quarantine system can be made 100 per cent failsafe after the disease escaped South Australia's isolation regime.

* The prime minister is hopeful SA's harsh COVID-19 measures will be short-lived and avoid a long lockdown similar to Melbourne.

* Victoria will effectively close its border to South Australia for 48 hours after virus fragments were detected in wastewater along two freight corridors.

* Premier Daniel Andrews says the "hard border" will be in place from 11:59pm on Thursday, before a permit system is introduced on Sunday.

* Victoria recorded its 20th consecutive day with no coronavirus cases or deaths on Thursday.

* The Western Australian government doesn't plan to stop security guards from taking up other jobs despite the risk they could spread the virus. There were no new cases reported in WA on Thursday.

* Queensland Health Minister Yvette D'Ath believes the state was singled out for criticism by the federal government and has defended border measures in response to Adelaide's cluster. All three new cases recorded in Queensland on Thursday were detected in hotel quarantine.

* In NSW up to 3000 people will be allowed to gather outside, in a move to accommodate New Year's Eve celebrations. The state notched its 12th straight day of zero local cases on Thursday, with five new infections coming from hotel quarantine.
