Tom Hanks and wife Rita Wilson, who have been diagnosed with coronavirus, have visited several Australian travel hotspots in recent days.
Wilson performed at the Sydney Opera House just days before she was diagnosed with the deadly infection.
The singer-songwriter performed at the Opera House on Saturday and the Emporium Hotel in Brisbane's South Bank last Thursday.
It's not known if the star was infectious then.
Hanks has also been at Bondi Beach and the Gold Coast and Wilson appeared on Channel 9's Today Extra in Sydney.
