No new locally-transmitted COVID-19 cases were reported in the 24 hours to 9am (AEDT) on Wednesday with two cases reported in travellers already in hotel quarantine.

Premier Annastacia Palaszczuk says restrictions like mandatory facemasks in indoor public places and social distancing are "100 per cent" on track to be lifted at 1am on Friday.

"We've got one more day to go, it's all looking very positive, and we'll be able to advise the Greater Brisbane region tomorrow will be able to ease," she told reporters.

Chief Health Officer Jeannette Young said despite the lack of cases there were still traces of the virus being picked up in sewage testing across the state.

She said it was understandable sewage testing had detected the disease on the Gold Coast, where virus cases are in hotel quarantine, and Cairns, where it's believed a returned traveller is still shedding the virus.

However, Dr Young said a positive sewage testing result at Cannonvale in Mackay reinforced her call for people to keep coming forward to get tested, like the 7990 people who had done so in past 24 hours.

"(If) anyone, anywhere in the state has any symptoms at all, please come forward and get tested and isolate until you get a result that will then keep us all safe," she said.

The lack of new cases suggests that a cluster that emerged among staff and guests at the Grand Chancellor quarantine hotel in Brisbane, which triggered a three-day citywide lockdown, has not spread any further.

Ms Palaszczuk is still forging ahead with her proposal to move hotel quarantine out of Brisbane and into vacant outback mining camps to protect urban populations from the UK strain of coronavirus.

"The reason we're putting this proposal forward is that we're trying to minimise the risk with this incredibly infectious UK strain," she said.

"This is not a problem unique to Queensland, it is an issue for all of Australia.

"I'm looking forward to speaking with the prime minister later on this week to put forward some suggestions and some ideas, and hopefully also, we'll be raising it at national cabinet."

The premier said the government had identified one potential site near Gladstone but they were yet to determine others.

Ms Palaszczuk did rule out federal MP Bob Katter's proposal to repair the cyclone-damaged Dunk Island resort near Cairns and use it as a quarantine camp.

"We're in cyclone season as well and the logistics of evacuating people from that if if we had to would be incredible," she said.
