Queensland has recorded no new local cases of coronavirus in the past 24 hours amid concern about the possible spread of the highly contagious UK variant.
It comes as Greater Brisbane reaches the halfway point of its snap three-day lockdown.
More than 19,000 tests were conducted in the state over the past 24 hours and Premier Annastacia Palaszczuk thanked Queenslanders for complying with lockdown measures including the mandatory use of masks in public.
The UK variant has potentially been active in the community since 2 January but no locally acquired cases have yet been detected.
Queensland is on high alert after a cleaner at one of Brisbane's quarantine hotels was initially diagnosed with the variant.
Ms Palaszczuk said a total of 147 close contacts have now been identified, with 112 testing negative to date.
Residents in the council areas of Brisbane, Logan, Ipswich, Moreton Bay and Redlands must stay at home until 6pm on Monday except for essential work and shopping, exercise, to access healthcare or look after the vulnerable.
Ms Palaszczuk is expected to give another update at 9am on Monday.
