Queensland remains on alert about mystery COVID-19 infections on the Gold Coast after two new local cases were recorded in another part of the state.
Those cases involve a young girl and a woman who are linked to an infection in the Goondiwindi cluster.
Authorities say they consider the new cases to be low-risk as they both tested positive for COVID-19 while in isolation.
But the state's acting chief health officer Peter Aitken says they remain concerned by the two mystery cases that emerged on the Gold Coast this week.
"We're still uncertain at the moment as to how they've acquired COVID. We also know the genomics are identical," Dr Aitken told reporters on Friday.
"We're working through Gold Coast Public Health Unit and doing some amazing work at the moment, looking at all the movements for those two people, seeing if there's a common link."
Eleven more people have died with COVID-19 in Australia - nine in Victoria and two in NSW.
NSW has reported 286 cases as the final COVID-19 restrictions lift and people in NSW make plans to travel again.
The state government says during the pandemic they received thousands of complaints from people who unknowingly agreed to travel cancellation policies they were not happy with.
New information standards will clearly outline key terms and conditions of travel contracts relating to cancellations, refunds and credits, processing fees and any other important exclusions.
NSW Health's Dr Jeremy McAnulty says with more people likely to be travelling again soon, getting a booster shot is all the more important.
"Now that we have got over 90 per cent of people with double dose, it's important we focus on the booster program as well," he said.
"So people aged 18 years over can now receive a Pfizer vaccine as a booster if it's been six months or more since your last second dose and at this stage of the pandemic the onus is on all of us to keep each other safe."
In the Northern Territory, workers have until the end of Friday to get their first COVID-19 vaccine dose or face losing their jobs, and second doses will need to be complete by 24 December.
The new health directive makes it mandatory for most workers who interact with the public to have their first jab by midnight Friday.
If they're not vaccinated, workers won't be permitted to go to their workplace unless a new role can be found for them.
If they do work, they could be fined $5,000 for failing to comply with a mandated health directive.
Employees who must be vaccinated under NT law include those who come into contact with people at risk of severe illness from the virus, such as medically vulnerable Aboriginal and Torres Strait Islander people.
Victoria has reported 1,115 new locally-acquired COVID-19 cases, and the ACT 15 cases.
