NSW has recorded one new locally-acquired case of COVID-19 as Australia faces an anxious wait to see if a highly contagious UK variant of the virus has spread from Brisbane.
The single local COVID-19 case in the 24 hours to 8pm on Friday was a contact of a case linked to the Berala cluster, which now numbers 21. There were also five new cases in travellers in hotel quarantine.
The tally came from more than 25,000 tests.
On Friday, Queensland Premier Annastacia Palaszczuk announced Greater Brisbane would enter a three-day lockdown after a cleaner at a quarantine hotel was diagnosed with the more infectious UK virus variant.
The NSW government duly implemented a new public health order requiring anyone in NSW who had been in Greater Brisbane since 12.01am on 2 January to follow the same lockdown rules.
Travellers from the area will only be able to leave their house or accommodation until 6pm on Monday to shop, exercise, work, perform care or seek medical care.
People who have arrived in NSW since 2 January after transiting through Brisbane Airport will not be subject to the requirements.
Anyone already in transit from Greater Brisbane to NSW must abide by Queensland's isolation rules and act as if they had remained in Brisbane.
Acting Premier John Barilaro on Friday said NSW authorities were working with counterparts in Queensland but the state was not considering a hard border.
Queensland's COVID-19 case prompted Prime Minister Scott Morrison on Friday to reduce the number of international arrivals into NSW, WA and Queensland's hotel quarantine systems by 50 per cent.
The suburbs north of Narrabeen Bridge on Sydney's northern beaches, meanwhile, have been under stay-at-home orders since before Christmas but that restriction is due to be lifted from Sunday.
"We can't thank you enough for your patience and compliance and high rates of testing occurring through the northern beaches during this time, it is deeply, deeply appreciated," Premier Gladys Berejiklian said on Saturday.
"That cluster is in the main under control but we still have to maintain our vigilance."
