TRACES of COVID-19 have been found in wastewater at Cleveland.
The virus that causes COVID-19 also has been detected at the Gold Coast, North Cairns, and Townsville.
Queensland's Chief Health Officer Jeannette Young said any wastewater detections highlight the importance of getting tested if people had symptoms of COVID-19.
"With the current situation in New South Wales and these positive wastewater results, I really need anyone who has any symptoms to come forward for testing," she said.
"We can't be complacent here. We might be doing well in Queensland, but that can all change really quickly, as we've seen in other states.
"Please, keep getting tested, and keep following the health advice around maintaining distance, putting your contact details down at venues, and washing your hands."
It comes as Health Minister Yvette D'Ath announces that from Sunday, December 20, anyone entering Queensland from New South Wales will need to have a border pass declaration.
Anyone travelling from Sydney's Northern Beaches, including returning Queenslanders, must go into mandatory 14-day hotel quarantine.
Ms D'Ath said anyone entering Queensland from Greater Sydney or the Central Coast should get tested on entry to the state and self-quarantine until they received results.
"We're adding additional measures to keep Queenslanders safe and we're encouraging anyone in Queensland who has COVID symptoms, whether they've been travelling or not, to get tested," she said.
"I'd also urge anyone in Queensland to reconsider travel plans to New South Wales.
"New South Wales is doing a great job and we hope this cluster is contained to the Northern Beaches area, but if we start to see spread into Sydney and surrounds, we will not hesitate to implement extra hotspots.
"We hope not to have to do that, but my message to Queenslanders is, now is not the time to be in Sydney.
In addition, please follow the advice that applies in all instances:
- Stay 1.5 metres away from other people-think two big steps.
- Wash your hands frequently with soap and water or use hand sanitiser after physical contact with other people or commonly touched surfaces.
- Sneeze or cough into your arm or a tissue. Then put the tissue in the bin and wash or sanitise your hands.
- Comply with current public health directions.
