Queensland has declared Waverley in eastern Sydney a coronavirus hotspot and all visitors who have been to the area will have to enter hotel quarantine on arrival.
Residents or people who have visited the Waverley Council area in the past 14 days will be ordered into hotel quarantine on arrival in Queensland from 1am on Saturday.
Queensland Health Minister Yvette D'Ath says the declaration comes after one of two recent COVID-19 cases announced in NSW were believed to have picked up the virus from "fleeting contact".
"They're saying they believe it was fleeting contact, which is why we need to do this," she told reporters on Friday.
"It's really important that anyone in Queensland reconsiders their need at this point in time to travel to anywhere in Sydney."
Ms D'Ath said visitors from the rest of Sydney would be allowed to come to Queensland because no cases had been reported outside the Waverley Council area.
However, Chief Health Officer Jeannette Young foreshadowed that the travel restriction area could be further widened depending on the virus cluster's growth in Sydney.
"People need to reconsider whether or not they should be travelling to Greater Sydney at this time," she said.
"And they need to be prepared, that they may need to, when they come back, go to government hotel quarantine for 14 days."
No new virus cases in the community were reported in Queensland on Friday, but there were three new cases in hotel quarantine.
