Queensland looking closely at NSW border as cases surge in Sydney

"We are delighted that through the hard work of Queensland that we have gotten to that situation today," Ms Palaszczuk said.

"Well done everyone and let's keep up the good work."

There are 8679 people in quarantine, with Queensland's Chief Health Officer Dr Jeannette Young warning the state was not quite out of the woods yet.

"We are not totally out of it yet," she said.

"We must keep up quarantine and testing."

All eyes on Sydney outbreak

With NSW recording another 44 new cases overnight, tightened restrictions were today announced for Greater Sydney.

The region is looking less and less likely to come out of lockdown next Friday as planned.

Ms Palaszczuk today said Queensland authorities were looking closely at whether the Queensland border will once again have to be shut to all of New South Wales.

Health minister 'confident'

Queensland's Health Minister Yvette D'Ath said it was the "best press conference ever" to be able to announce there were zero new cases in the state.

Dr D'Ath said health officials were "confident" the outbreak could be eradicated as the state's 8000 close contacts were in quarantine.

"The lockdown that we had allowed us to contact traces and to contain those contacts into quarantine so that they are already away from the community when they were infectious," she said.

"This is a great outcome for everyone."

Logan Hospital from the main entrance to the antenatal clinic on Monday June 28 from 8.30am to 8.40am and 9.20am and 9.30am was the only place added to the list of exposure sites today.

Queensland's check-in app became mandatory across a range of venues from today.

Residents in the affected Local Government Areas across South East Queensland, Townsville and Palm Island must keep wearing masks for another week.

There have been instances of Queensland police officers being "abused and treated poorly" by members of the public breaching the state's mask mandate.

"The message to the community is to carry on wearing masks ... if you push back you will face a fine and potentially more serious offences," Deputy Commissioner Steve Gollschewski said.
