The Queensland government is on alert over the 65-case outbreak in Sydney as it eases social distancing restrictions and deals with a local virus cluster in Brisbane.

The Brisbane cluster grew by two cases to seven on Friday, but all are linked and believed to be the Alpha variant.

Queensland Chief Health Officer Jeannette Young is more concerned about the Delta variant spreading from Sydney.

"So I'm not concerned about (the Brisbane cluster), but we are continuing to see cases in NSW ... we could have a case in Queensland any day," she told reporters on Friday.

Dr Young has ordered anyone in Queensland who has been in Waverley, Woollahra, Randwick or the City of Sydney since June 11 into a seven-day lockdown.

Interstate arrivals who have been in any of those local government areas since June 11 will be ordered into hotel quarantine on entry into Queensland.

Deputy Premier Steven Miles said 314 people who had been in declared Sydney hotspots tried to fly into Queensland on Thursday.

He said 186 were sent back, while 128 were ordered into hotel quarantine.

Mr Miles says border declaration passes will be mandatory from 1am on Monday for anyone who has been in NSW.

That includes border region residents as far south as Yamba, however those people will only need to apply for a pass every 14 days.

Dr Young urged Queenslanders to reconsider plans to travel to NSW.

"People should really reconsider their need to go anywhere in NSW," she said.

"If it's urgent, unavoidable, of course they should travel, but if it's not perhaps they should think about holidaying in Queensland."

The two new local virus cases reported in Brisbane on Friday were in quarantine during their infectious period and are being closely monitored.

There are now seven COVID-19 cases in the Brisbane cluster, all of which are linked and believed to be the Alpha variant.

Six became infected after coming into contact with a flight attendant who caught the virus in hotel quarantine.

The woman visited the Portuguese Family Centre in Ellen Grove and DFO at Brisbane Airport on Saturday before she tested positive.

The outbreak comes as the state winds back social distancing rules and ramps up the number of venues that must use the state's check-in app.

Indoor venues, weddings and funerals will be allowed to have density of three people per four square metres, or 100 per cent capacity with ticketed seating.

Meanwhile, the check-in app is mandatory for accommodation providers, hospitals and aged care providers.

The Queensland government is also considering a new federal proposal for a mass COVID-19 quarantine facility near Brisbane Airport.

Prime Minister Scott Morrison is offering to pay for the 1000-bed facility on the site of the Damascus Barracks at Pinkenba.

Under the proposal, the state government would build and operate the hub.

The Pinkenba plan puts the state's proposed quarantine facility at Wellcamp Airport, near Toowoomba, in doubt.

The Wagner Corporation wants to build a facility that would host up to 1000 travellers and 300 staff at Wellcamp.

A verbal stoush between the federal and state governments over the Wellcamp plan has been running since January.

Mr Miles said the state had received scant information on the Pinkenba proposal, the details of which were given to a newspaper first.

"This was a one-and-a-half page letter received by us late last night, just after it was provided to The Courier-Mail," the deputy premier said.

"The only detail in the letter is an address, and I just note that when Queensland provided a 15-page early proposal we were told that that was far too little detail.

"Now we will work with the Commonwealth through that detail. Our officers have already started analysis on that site, but there is a lot more work to be done."
