The Hotel Grand Chancellor has been linked to the UK strain of coronavirus.
Six cases of coronavirus in Queensland have been found to be the highly contagious UK strain of coronavirus, and all have been linked to the Grand Chancellor Hotel.
Genomic testing of all the cases found the links between all six.
"These are the UK traveller and his partner, the hotel cleaner and her partner, and the man and his daughter from Lebanon who we told you about yesterday," Premier Annastacia Palaszczuk said.
"So all six have a connection to the Grand Chancellor Hotel."
As a precautionary measure, all guests in quarantine at the Grand Chancellor are being moved to other hotels.
And 250 guests who were in the hotel previously will be tested and quarantined.
Only two new cases of coronavirus have been diagnosed in Queensland in the past 24 hours, both in hotel quarantine.
Ms. Palaszczuk said it comes after 20,615 tests were conducted yesterday.
"So once again, congratulations to everyone who has been coming in and getting tested, and if you have any symptoms, make sure that you do that," she said.
"So everything we have done in the past six days is because of the arrival of the highly infectious UK strain of COVID."
Yesterday Queensland recorded one new coronavirus case from local transmission – the partner of a hotel cleaner who had contracted the highly infectious UK strain last week.
Local residents exercise near Southbank, towards the end of Brisbane's three-day lockdown.
Two other cases were diagnosed in a father and daughter in hotel quarantine.
In Victoria today, no new local cases were recorded after 17,908 tests yesterday.
But there were three cases in hotel quarantine.
