The Queensland government is trying to ramp up COVID-19 vaccinations before Delta reappears in the state, after bringing another outbreak under control.
The state recorded no new cases in the 24 hours to 6.30am on Tuesday as 900 families were released from home quarantine by authorities.
The families had been potentially exposed to a four-year-old girl at a school and a daycare centre in the Beenleigh area, but all children in the families have since tested negative.
Premier Annastacia Palaszczuk says the immediate threat from the outbreak, which peaked at three cases, has passed.
"In some excellent news today, it's a double Donut Day, so zero cases, which is fantastic so well done Queensland," Ms Palaszczuk told reporters on Tuesday.
However, she says the threat of Delta spreading from NSW remains high and the state is ramping up vaccinations with a new mass hub opening at Boondall, on Brisbane's north side on Tuesday.
The centre will initially administer 1500 vaccinations per day before will ramp up to 3000 next week.
More mobile vaccination clinics will be rolled out in the far north and the government will also soon start texting Queenslanders about where and when they can get vaccinated near where they live.
Deputy Premier Steven Miles said there was now a window of opportunity to get the jab before the Delta strain gets into Queensland.
"We are desperately holding that window open," he said.
"That's what our border restrictions and other restrictions are doing, we're holding the window open for as long as we possibly can to get as many Queenslanders vaccinated as we possibly can before the Delta strain arrives."
Queensland has the lowest vaccination coverage in the country, with 53.33 per cent of eligible people having had one dose and 34.75 per cent fully vaccinated.
Mr Miles said federal Health Minister Greg Hunt criticism of Queensland was unfair given a higher proportion of Pfizer jabs are being redirected to the NSW outbreak.
"The nerve of Greg Hunt, to be out there criticising Queensland," he said.
"He's calling us laggards, when he knows full well how many vaccines he's taking from Qld to give to NSW, and he knows full well that we are fully utilising our allocation."
Queensland has been fully utilising vaccine doses since the beginning of September, Health Minister Yvette D'Ath said.
She said if "we are really all in this together" then Prime Minister Scott Morrison should just boost Pfizer supplies to Queensland as well:
"Stop picking fights and stop criticising the two states that have been the most successful in managing this virus, and help us get our community vaccinated."
Ms Palaszczuk said once the government has a clear indication of Commonwealth vaccine supplies over the next six to eight weeks it will release forecasts of when Queensland will hit 80 per cent vaccination coverage.
She said she hopes Queenslanders will be able to travel around Australia by Christmas.
"I really hope that Queenslanders will be able able to travel but we just need to see," the premier said.
"It's when the whole of the country gets to that stage, but we already do have states that are open to travel."
