The woman was an external contractor at the Rookwood Weir project west of Rockhampton and tested positive on July 31.
It’s believed she was infectious when she took a Qantas flight from Brisbane to Rockhampton on July 28 and a return flight on July 30.
Authorities are contacting people who were on QF2362 at 8.30am on July 28 and QF2365 at 6.40pm on 30 July.
They are also urgently testing workers at the weir work camp, who are in their rooms for 14 days’ quarantine, while on site work has been called off, and other workers who were at the site have been contacted and told to isolate.
The case means the potential exposure sites linked to the Queensland outbreak have spread well beyond the state’s southeast, where a three-day lockdown is under way.
Queensland reported nine new local COVID-19 cases on Sunday, the highest number in almost a year.
There are more than 80 exposure sites linked to the outbreak, with about 20 new sites of concern listed on Sunday.
New locations include sites in Pullenvale, Moggill, St Lucia, Spring Hill, South Brisbane, Sunnybank, Bellbowrie and Wilston, as well as bus routes 28 and 411.
Also on Sunday, Deputy Premier Steven Miles said implored more Queenslanders to seek virus testing, with fewer than 12,000 tests conducted on Saturday.
Authorities hope to see at least 40,000 daily tests.
The local government areas of Brisbane, Ipswich, Logan City, Moreton Bay, Redlands, Sunshine Coast, Gold Coast, Noosa, Somerset, Lockyer Valley and Scenic Rim went into the lockdown on Saturday afternoon.
Non-essential travel must be within 10 kilometres of residences and everyone must wear a mask when outside their home.
All schools in the lockdown zone will be closed on Monday and Tuesday, while all staff and students of Indooroopilly High School and Ironside State School are in quarantine for two weeks.
Other schools affected by the outbreak include St Peters Lutheran College, Brisbane Girls Grammar School and Brisbane Boys Grammar School.Jump to next article
