The woman and her husband left Melbourne on 1 June, during the state’s recent lockdown. The pair travelled through NSW and arrived in Queensland on 5 June.
The woman’s husband has so far tested negative and there are five other identified close contacts. Young said the pair were staying with family in Caloundra.
Young said it was too early to discuss whether Queensland would need to enter a lockdown. She said there was no evidence yet of local transmission in Queensland as the woman contracted the virus in Victoria.
A police spokesperson told reporters they were investigating how the couple entered Queensland and it was “too early” to say whether they had committed any breaches of health directions.
