Queensland has recorded zero locally acquired cases of COVID-19.
Health Minister Yvette D'Ath said Gold Coast residents were still urged to get tested as contact tracers sought the source of two local infections that emerged in the region earlier this week.
Acting Chief Health Officer Peter Aitken said the region was not out of the woods yet.
"At this stage, there's no defined link [between the cases]," Dr Aitken said.
"But the close contacts have all been followed up and they're in the process of being tested and all test results at this stage have been negative."
"We'd obviously like to get through a full 14-days incubation period and, importantly, if you've got symptoms get tested … and vaccinated if you haven't been already," he said.
New South Wales health authorities said a case of COVID-19 had been detected on the border in the Tweed Shire Council area.
It comes as the state inches closer to hitting the 70 per cent double-dose vaccination milestone.
Just over 81.11 per cent of Queenslanders aged over 16 have now received at least one dose of a COVID-19 vaccine, while 69.39 per cent have had two.
Ms D'Ath said the state was expected to hit the target on Sunday or Monday, paving the way for people to enter from interstate hotspots.
They must be fully vaccinated, arrive by air, have had a negative COVID-19 test within the previous 72 hours and undertake 14 days' home quarantine.
Speaking from Bray Park State High School in the Moreton Bay region, Ms D'Ath said there were now 58 schools involved in the rollout of the vaccine.
This weekend marks another 'super school' vaccination blitz in areas across the state with lagging uptake.
"We've had three days in a row of more than 17,000 vaccinations," Ms D'Ath said.
"They've been such a success in the past and we'll have even more schools open next week."
Streamlined border pass system set to go live
Ms D'Ath said interstate travellers from hotspots would be able to apply for a border pass as soon as Queensland hit the 70 per cent double-dose target.
"If you can meet all that criteria, the border pass will be automatic, so you won't have to wait one, two, three days to get that approval," Ms D'Ath said.
"So when we hit that 70 per cent mark … people can start booking their flights, going off and getting their [COVID-19] test and waiting for their negative result."
"Once they've got all that information — they've got their vaccination status, their negative test and their flights booked — they can go onto the border pass system and they'll be able to put all that in."
Ms D'Ath said penalties would apply to anyone trying to game the system.
"[If] they provide false information, they will get fined," Ms D'Ath said.
"There will be checks on those documents, there will be checks at the airports and there will checks while you're in home quarantine."
"If someone turns up at an airport and they do not have the proper pass, or they haven't met the criteria, they will either go into hotel quarantine or they'll be turned around."
'Long way to go' for Gold Coast community
Meanwhile, Dr Aitken said it was encouraging to see testing rates had doubled on the Gold Coast in recent days.
"But there's still a long way to go," Dr Aitken said.
With Schoolies Week fast approaching and large crowds expected at the Coolangatta Gold Surf Life Saving Ironman event and Groundwater music festival at Broadbeach this weekend, authorities are particularly eager to drive up vaccination.
Dr Aitken urged those attending events to wear a mask.
"If you are in crowded places, particularly on the Gold Coast … when you can't socially distance, it is important to wear a mask," Dr Aitken said.
Nineteen cases remain active across the state after 9,212 tests were conducted in the past 24 hours.
