The new case is the husband of the 44-year-old Melbourne woman who tested positive on the Sunshine Coast on Thursday, almost a week after she first developed symptoms on June 3.
They are both in quarantine at the Sunshine Coast University Hospital.
The pair left Victoria on June 1, four days into Victoria’s lockdown, and travelled through regional NSW before crossing into Queensland at the Goondiwindi border.
Queensland and NSW had, at the time, closed their border to Victoria.
All three states have scrambled to track the pair’s movements and test anyone who came into contact with them.
There were six new cases of Covid-19 detected in hotel quarantine as of Thursday morning.
