Two cases of COVID-19 that were detected on a superyacht off Cairns have now been classified as historical.
In an update released late this afternoon, Queensland Health advised the two cases were no longer considered active.
The cases were announced last week as being a woman in her 20s and a man in his 30s.
"Any individual who returns a positive COVID-19 test result in Queensland is interviewed," the update said.
"If required, further testing is undertaken to better understand the circumstance around their infection.
"One reason for further testing is to assist in determining if the positive test result relates to a new infection or is the result of prolonged shedding of the virus, which is seen in some people with an historical infection with COVID-19."
