Queensland has no new coronavirus cases as it nears the 14-day milestone of no community transmissions required before health authorities will consider lifting restrictions in the state's southeast.
The number of active cases fell to just five, down from 16 on Tuesday.
Health Minister Steven Miles confirmed it has been 13 days since a case not linked to a known cluster has been recorded in the community.
"Today is a truly fantastic day," he told reporters on the Gold Coast.
"It's day 13 as we track whether we have successfully suppressed those related clusters from the Brisbane Youth Detention Centre, the Corrections Training Academy and the Ipswich Hospital."
Those outbreaks lead to 55 infections and are believed to be linked to two young women who flouted Queensland's quarantine rules after returning from Melbourne in June.
Mr Miles said Queensland could record zero cases right the way through October.
"Let's keep it up, let's keep going, let's make sure it's the economy that rebounds and not this virus," he said.
The latest figures follow the announcement on Tuesday that Queensland will extend its border travel bubble 100km into NSW.
About 152,000 residents of Byron Shire, Lismore, Richmond Valley and Glenn Innes will be allowed to travel freely in Queensland from October 1.
ACT residents will also be allowed to fly into the Sunshine State without having to undergo mandatory 14-day quarantine from Thursday.
But Mr Miles said borders would stay shut to the rest of NSW until at least the end of the month and it remained unlikely they would reopen in October.
"We'll continue to monitor NSW and Victoria ... we'll ease those restrictions as we can safely do so."
Mr Miles said Queensland would maintain its "cautious" approach but admitted the extended border bubble "does create a risk" of another outbreak.
Health authorities require NSW to go 28 days without a case of community transmission before the border will reopen, although chief health officer Jeanette Young has previously flagged that criteria could change.
Wednesday also marked a personal milestone for Queensland's longest-suffering coronavirus patient, Richar Misior, who was transferred from acute treatment into a rehabilitation unit at Gold Coast University Hospital.
The 81-year-old, who was a passenger on the Ruby Princess, spent 77 days in intensive care after contracting the virus.
