The woman in her 50s was active in Brisbane's northern suburbs, and Chief Health Officer Jeannette Young says she has no known links to existing cases or exposure sites.

All of her household members have so far tested negative, and Dr Young said she had received both vaccination doses.

"I am reasonably reassured by all that, but it would be good to see that enhanced testing response," she told reporters on Monday.

It was also encouraging no other chains of transmission were identified by more than 100,000 tests over the past week, Dr Young said.

Genome sequencing results are expected shortly to help determine the source of the infection.

New contact tracing locations, including a number of massage parlours, have been listed for Redcliffe, Cannon Hill, Slacks Creek, Boondall, Bracken Ridge, Chermside and Archerfield.

Two new overseas-acquired cases were also recorded in hotel quarantine.

Queensland is now managing 26 active cases.

The state has also introduced tighter border restrictions for Lismore following stay-at-home orders announced by NSW.

Meanwhile, a lack of real-time data from Queensland public hospitals is making it difficult to plan for potential outbreaks when the state opens to the rest of the country, a group of medical professionals has warned.

While some data is available, emergency physician Kim Hansen said she couldn't see the ward beds available in her hospital, nor throughout the entire health system.

"Our hospitals should be operating at 90 per cent capacity, not more than 100 per cent like we currently are, to allow patients to flow from the emergency department through the hospital and then back in to the community," she said.

"We're talking more about the ward beds, the emergency beds are well monitored and the ambulances are well monitored."

The doctors gathered for a roundtable meeting to discuss the "ramping crisis" before interstate borders reopen later this year.

Available hospital beds that were staffed for emergency patients were more important than the number of beds overall, Dr Hansen said.

Dr Young said real-time data was already used to direct ambulances to a particular hospital.

She pushed for an increased vaccination rate to prevent further pressure on the health system.

"We know that decreases the need for hospitalisation," she said.
