Queensland Premier Annastacia Palaszczuk says she is considering using mining camps to quarantine international travellers, and will raise the option at tomorrow's national cabinet meeting.

The proposal comes after a highly-infectious variant of COVID-19 was linked to six infections on the same floor of a Brisbane quarantine hotel.

“Was it in the air conditioning? Was it movement? Was it picking up something? We just don't know those answers yet," Palaszczuk said
