Several venues of concern in Brisbane have been identified, including a gym, pub and cafe.

Anyone who has attended one of the venues listed on the website during the relevant times is asked to immediately self-isolate until Thursday, March 25.

If you are currently in NSW and have been to any of the venues, please call NSW Health on 1800 943 553.

Anyone who has entered NSW from Greater Brisbane since Thursday 11 March 2021 and who has not attended any of the venues listed above must still be alert for symptoms.

Greater Brisbane is defined as Brisbane, Ipswich, Logan, Moreton Bay, and Redland.

If symptoms occur, you should get tested immediately and isolate until you receive a negative result.
