A Toowoomba man who "escaped" quarantine had earlier been stopped by police at the Goondiwindi border checkpoint prior to going into quarantine.
It was earlier reported that he had been stopped after escaping quarantine.
This was incorrect.
The escape has sparked an independent police investigation into the 25year-old's disappearance and the police service's hotel quarantine procedures.
Police Minister Mark Ryan told State Parliament earlier on Wednesday the man was nine days into his mandatory 14-day quarantine period when he disappeared.
"It doesn't appear that he was assisted by anyone, we believe he worked out a way to leave [hotel quarantine] and he has left," Queensland Police Deputy Commissioner Steve Gollschewski told media.
"He had previously been tested and tested negative, but we are expediting a further test of that person to ensure they remain COVID-negative and to give assurances to the community that while he was out there, there has been no spread of COVID.
"That person was previously charged with some other criminal offences and also attempting to get into Queensland unlawfully. He will appear in Goondiwindi Magistrates Court in September."
"We will be looking at whether it is a systemic issue or whether it was an error ... We're being very transparent around this, it is not good enough."
All of Queensland's hotel quarantine is handled by police with the support of other agencies such as Queensland Health or the Australian Defence Force. There are no private security guards used.
LNP leader Deb Frecklington said Queenslanders must be kept safe to protect lives and livelihoods.
This is yet another case where Labor has failed to enforce hotel quarantine and it's put Queenslanders at risk.
Strict enforcement of hotel quarantine is crucial to keeping Queenslanders safe.
The Palaszczuk Labor Government needs to explain why their quarantine system failed and how this man was able to breach restrictions.
Time and time again, gaps in Labor's enforcement of coronavirus restrictions have been exposed.
Queenslanders have seen what a lax quarantine arrangement has done in Victoria.
A second wave would be devastating to the Queensland economy and cost thousands of jobs - it can't be risked.
Anyone found deliberately breaching the restrictions should face the maximum penalty - $13,345 fine or six months jail.
