Adelaide lockdown over, Vic rules to ease

South Australian Premier Steven Marshall remains "very concerned" about the Adelaide cluster.

Freedom is returning to the nation's south as Adelaide residents emerge from several days of strict lockdown and Victoria is poised for final steps out of COVID-19 restrictions.

Premier Daniel Andrews is expected on Sunday to announce increased numbers for gatherings and hospitality.

The state is on the cusp of eradicating the virus with just one active case following 22 days of no transmission.

Overnight, Victoria replaced its brief "hard border" with South Australia with a permit system.

SA residents entering Victoria must obtain a permit via the Services Victoria website.

Cross-border communities do not have to get a Victorian permit but can use their SA government-issued permit, which they used for months when SA shut its border to Victoria.

Adelaide is emerging earlier than planned from a "circuit breaker" shutdown to control a cluster at Parafield.

One new case was recorded on Saturday - the partner of a positive case - bringing the cluster to 26.

Premier Steven Marshall remains "very concerned" about the Adelaide cluster and said on Saturday there were many possible contacts yet to be identified.

Investigations continue into a pizza shop worker who lied to contact tracers about his whereabouts, sparking the lockdown.

He is believed to be a 36-year-old Spaniard living in Australia on a temporary graduate visa.

Police also want to speak to two other people of interest as part of the investigation, which is being undertaken by 20 detectives.

NSW has reached a milestone of two weeks without a locally transmitted case, though Queensland wants to see 28 transmission-free days before fully relaxing its southern border.

Ten cases of the virus were diagnosed in NSW hotel quarantine in the past 24 hours, with the state now managing 70 cases in travellers.

Victoria will begin to share the burden of international travellers from December 7 with a revised hotel quarantine system. Initially, it will take 160 people a day.

Victorian authorities are analysing virus traces detected in a wastewater sample collected from the Altona sewage catchment on Wednesday.

The result is unexpected because it has been about eight weeks since someone in the area tested positive.

Prime Minister Scott Morrison remains in quarantine at The Lodge in Canberra, in line with national travel rules following his visit to Japan to meet new Prime Minister Yoshihide Suga.
