This is the second vessel in less than a week.
Pacific Explorer's arrival marked the end of a 9-day roundtrip Queensland voyage themed "Barrier Reef Discovery". The boat was carrying ~3000 passengers and crew.
All COVID-positive passengers are confined to their staterooms and have even been issued with red tags for their cabin doors to keep the staff from coming inside.
On arrival, passengers who wish to disembark will have to provide a negative rapid antigen test for SARS-CoV-2.
