Despite recording no new cases, health officials are urging all Queenslanders to remain vigilant as concerns grow about the growing Sydney cluster and the emerging cases in Victoria.
Fragments of COVID have also been detected in sewage on the Gold Coast and in West Moreton in the last week.
Anyone who develops even the mildest of symptoms is advised to get tested immediately and isolate.
Queenslanders are also being advised to reassess plans to travel to either New South Wales or Victoria.
While the state is yet to extend its border closure beyond Greater Sydney, officials warn that could change at any moment.
