There are two new local cases of COVID-19 in Queensland today, including an international airport worker who has been infectious in the community since last Friday.
One of today's cases is a close contact from the Portuguese restaurant cluster who had been in isolation.
The second case is a 37-year-old woman who works at the Qatar check-in counter at Brisbane's international airport.

The woman began feeling unwell and went to get a COVID-19 test on Tuesday which returned a positive result.
"She has been to very limited places around her local area," Ms Palaszczuk said.
"We are very encouraged at the moment that we've only really got those two cases - very encouraging news today."
However, she cautioned that the state was "not out of the woods yet", with tomorrow's case numbers likely to determine whether lockdown restrictions would be eased as planned at 6pm that day.
Chief Health Officer Dr Jeanette Young has praised Queenslanders for turning out to get tested, with 29,990 tests conducted yesterday.
There were also 18,162 vaccines administered.

Dr Young said the international check-in worker "likely" caught COVID-19 while working at the airport.
"She would be checking in, not only the passengers, but she would be involved with the crew," Dr Young noted.
"We do know that international flight crew are high risk.
"They don't stay here for 14 days after they arrived - they fly in and fly out so we don't always know which of them are positive."
The 37-year-old developed symptoms on Sunday, meaning she has likely been infectious since last Friday, June 25.
She has one household contact who is being urgently tested, along with other close contacts.
The woman visited Officeworks in North Lakes on June 25, Coles at Murrumba Downs on June 27 and regularly goes to her local gym, Anytime Fitness in Griffith.
The exact dates and times for those exposure sites will be confirmed by Queensland Health later today.
She also interacted with her colleagues from Menzies Aviation on June 26 and 28.
Queensland's Deputy Premier slams increasing air travel
Queensland Deputy Premier Steven Miles has again claimed more foreign travellers are landing in Australia, saying it is putting a great strain on the quarantine system.
"(The Australian Border Force) did not dispute the growing trend for an increased number of foreign nationals being permitted to travel," he said.
"If you look at the ABS report that's what it points to, an increase in the number of foreigners travelling here, as well as the increase in the number of Australians travelling since the borders were closed last year.
"I know there has been some analysis today of arrival card data which also confirmed the high number of people travelling for leisure and business purposes.
"I think when Australians think about international travel when the borders are closed and think about hotel quarantine, they think about Australians coming home or the occasional highly skilled worker needed here or genuine hardship cases, they don't think about people coming and going about their regular business."
