"It is good to see that despite the enormous increase in testing, which I'm very grateful for, we have not had any other cases", she said.
'Police investigators have not found any evidence to warrant action being taken against a man following reports of a house party involving people in quarantine at Strathpine'. Upon arrival in Victoria, you'll also have to self-isolate immediately, get a coronavirus test within 72 hours of arriving and stay in isolation until you return a negative result.
The man, from Strathpine - a suburb in the Moreton Bay Region on the outskirts of Brisbane, roughly 22 kilometres north of the CBD - tested positive for the virus on Friday night, Queensland Health confirmed.
The man has the United Kingdom variant of COVID-19, which is considered more unsafe.
Health officials have been scrambling to find the source of the latest outbreak, after the 26-year-old and his friend, who also contracted the virus, visited several venues across Brisbane while they were potentially contagious. Along with the nine venues visited by the Stafford man, there are now 24 venues that are considered possible exposure sites.
A third person tested positive on Saturday.
Premier Annastacia Palaszczuk urged residents to maintain social-distancing and get tested.
The places include bars, breweries and shops, including a large Westfield and an inner city grocery store.
"This is a huge job now that we have to do because we've got more of this community transmission", Premier Annastacia Palasczuk said.
The family-owned Mamma's Italian Restaurant in Redcliffe, where the Stafford man spent three hours last Sunday, announced it would close until after Easter after the government toughened directions, ordering anyone who was there to go into 14 days of quarantine.
Palaszczuk revealed concerns that case numbers could rapidly increase through the week.
Queensland Health say that the unnamed man, aged in his 20s, received a positive test result on Friday night, and that around 25 people who attended the party have been ordered to isolate.
Australia's major sporting codes are again dealing with a significant Covid-19 disruption after Brisbane was plunged into a minimum three-day lockdown.
Queensland Health authorities are expected to provide more information throughout the day, particularly regarding venues of concern.
Because of some of the new infections travelling to either Gladstone or Byron Bay, the rest of Queensland is also getting a fresh set of restrictions.
Australia has reported just over 29,000 cases and 909 deaths since the pandemic began - a number far lower than many nations.
