Queensland is set to review its border bubble for two NSW border regions, which are going into lockdown after a new COVID-19 case emerged there.
Byron Bay and Tweed Shire are currently within Queensland's border bubble, from which residents can cross into the state for work, education, compassionate care or essential shopping, provided they've had one vaccine dose.
However, the NSW government will lock down both shires from 5pm on Tuesday after a COVID-19 case was infectious in them last week.
Earlier on Tuesday, Queensland Premier Annastacia Palaszczuk foreshadowed changes to the border bubble.
"The concern is, of course, if there are cases in northern NSW," Ms Palaszczuk told reporters on Tuesday.
"That will present a real risk to the southern parts of the Gold Coast, where I have thousands of families holidaying on the Gold Coast at the moment.
"So we're watching it very closely, so we'll be waiting to see what NSW says, and then I just ask people to listen to see what the chief health officer does after that.
"So let's wait and see at the moment, I'm sorry I can't give you any further update we need to hear from NSW."
If Byron and Tweed leave the bubble it will complicate interstate travel for other border zone residents further south.
For Ballina, Richmond Valley and Clarence Valley shires residents the most direct route to Queensland is via Byron and Tweed.
Queensland is already restricting travel from number of NSW local government areas in the border zone.
Those include Bourke, Brewarrina, Broken Hill, Glen Innes Severn, Lismore, Walgett Shire and the Unincorporated Far West.
Residents of those areas, where there are active virus cases, are only allowed to cross in Queensland for essential work, emergency volunteering and other essential purposes.
Queensland recorded zero new locally-acquired cases of COVID-19 on Tuesday, while one new case emerged in hotel quarantine.
Queensland Health administered 20,512 vaccine doses in the 24 hours to 6am, meaning more than 60 per cent of eligible residents who have had one dose.
Ms Palaszczuk urged people, particularly seniors, not to believe misinformation they may read online about vaccines.
She also took aim at a Courier-Mail report that cabinet had approved a plan to wait until vaccination coverage reached 90 per cent to reopen the borders.
"That is misinformation that was being peddled today," Ms Palaszczuk.
"Let me say categorically, national cabinet is working on a national plan. We are waiting for further information to come from the Doherty modelling to national cabinet in a fortnight's time.
"In the meantime, let me say very clearly to Queensland, it is important to get vaccinated, we are now at 60 per cent, we need to get as many people as possible vaccinated to protect our lifestyle, to protect our freedoms."
The Queensland government hasn't committed to any particular vaccine coverage target for reopening the state borders.
