A Melbourne couple who broke lockdown and travelled through NSW and Queensland could be facing punishments from all three states, including jail time.

Queensland is dealing with two interstate-acquired cases after the 44-year-old woman and her husband left Victoria while unknowingly infected and went on a road trip up the Sunshine Coast.

The pair left Victoria on June 1st, just days after the statewide lockdown had been enforced and travelled through NSW and Queensland before the woman tested positive to COVID-19 on June 8.

Queensland Health confirmed yesterday that her husband had also tested positive for the virus, with the pair currently in isolation at the Sunshine Coast University Hospital.

Queensland's chief health official Dr Jeannette Young confirmed that the couple did not have an exemption to enter the state and questions are being raised about why there was not a two-week hotel quarantine upon entry.

Health Minister Yvette D’Ath said on Thursday there was a “range of penalties” for people who broke travel border rules.

Breaching border requirements in Queensland could result in an on-the-spot fine of 4,003, a court-imposed penalty of up to $13,345 or six months' imprisonment.

Not complying with an NSW public health order could result in the maximum penalty of six months imprisonment and/or a fine of up to $11,000.

Dr Young said that on Thursday that it appeared that the couple were both towards the end of their infectious period, but it's still important for residents to come forward and get tested.

“It’s still there, and I still need everyone to come forward who develops any symptoms at all who lives in the Sunshine Coast, or Goondiwindi or Toowoomba – it’s very, very important,” she said.

“We’ve seen a lot of testing already started. That needs to continue, just so we can make sure that there hasn’t been any transmission out there.”
