Queensland’s aged care homes can now reopen to visitors, with authorities confident two infected teens who dodged quarantine did not spread coronavirus.

Health authorities had been on high alert for an outbreak linked to the women who spent a week moving around the community after returning from Melbourne in July.

“Today was the very important day,” Premier Annastacia Palaszczuk said, referring to the end of the two-week period since police placed the women in isolation.

“Aged care restrictions will be lifted, which I know means a lot to the families, especially over the last week or so when they have not been able to see their loved ones.”

Chief Health Officer Jeannette Young said there one new case of the virus diagnosed overnight, a man in mandatory hotel quarantine who recently returned from overseas.

“That is really good news, no community transmission in Queensland,” she said.

“We can safely reopen our aged care facilities to visitors.”

However, Bolton Clarke aged care facility in Brisbane’s southwest will need to remain closed for another day and a half.

“Until we have confirmation that potential outbreak is over,” Dr Young said.

The good news comes two days after the state’s border with NSW closed.

Police Deputy Commissioner Steve Gollschewski said roads at the border were “hectic” on Friday night in the hours before the closure and into Saturday morning.

“But over the weekend we’ve seen the roads, in particular, ease,” he said.

Since that time, Queensland police have checked 9946 vehicles attempting to enter the state, with 506 refused entry and 144 placed in quarantine.

Six people were refused entry at airports, with 197 people placed in quarantine.

Police also issued six fines for lying on the border declarations.

“Overall the system has worked very well although there have been some delays with the border declaration passes,” Mr Gollschewski said.

Mr Gollschewski also noted that police carried out 504 compliance checks of people quarantining at home and found 98 per cent were doing the right thing.

“Well done to those people and Queensland generally,” he said.
