Eight new cases have been identified in Queensland - seven in hotel quarantine and one historical case, which is believed to be the missing link to one of two clusters in Greater Brisbane.

Meanwhile, NSW recorded its second consecutive virus-free day after a case linked to the Queensland outbreak was diagnosed in Byron Bay earlier in the week.

However, concerns continue to surface over the rollout of vaccines, with Queensland almost out of the Pfizer inoculation and unsure when it will receive its next delivery.

The Pfizer vaccine has been used predominantly to vaccinate frontline healthcare and quarantine workers.

The federal government has copped flack over its handling of the vaccine rollout, with the slow pace blamed in part for Greater Brisbane's three-day lockdown.

A number of the healthcare workers who were infected in the region had not yet received their first dose.

"We should have a rolling list of ... when the deliveries are coming, and how much. That would just help everyone," Premier Annastacia Palaszczuk said on Friday.

Meanwhile, Queensland's historical case has been identified as a nurse who contracted the virus from a man who arrived from Europe last month.

The traveller has now been labelled the superspreader who infected a doctor in Brisbane's north that sparked the latest Queensland outbreak.

The nurse was the missing link in the first cluster.

Queensland's Chief Health Officer Jeannette Young said the nurse had been infectious between March 10 to 23, did not develop symptoms and had done nothing wrong.

"We managed to pick her up through being a contact, of course, and we have done the testing, and that's come back positive," Dr Young said.

"The nurse, again, through absolutely no fault of her own, has then gone home and transmitted to her partner, who is one of that group that we know who live in that north Brisbane area and a close social network.

"So then it spread within that network."

Dr Young said the cluster was now under control.

Several restrictions remain in place for the whole state during the next 14 days.

Queenslanders must wear a mask when indoors except when eating and drinking and must be seated in restaurants and pubs.

Gatherings in homes are capped at 30 people, and visits to hospitals, aged care and disability facilities and prisons are not allowed apart from end-of-life situations.

The good news in Queensland allowed Acting Chief Medical Officer Michael Kidd to lift the Greater Brisbane national hotspot declaration.

As of 6pm on Thursday, the Victorian government shifted the Greater Brisbane area from a red zone to an orange zone under its travel permit system.

This meant those in Victoria observing red zone permit conditions and quarantining for 14 days were designated orange zone arrivals and could end their isolation if they have returned a negative test result since arriving in Victoria.

However, it excluded primary close contacts linked to NSW and Queensland exposure sites, who must continue their self-isolation for 14 days since their exposure.

The ACT government has also reopened the national capital to people from Greater Brisbane without the need to fill out a declaration or exemption form.

People quarantining in the ACT were being advised directly by ACT Health about what to do next.

Tasmania is maintaining its travel restrictions with Greater Brisbane and will reassess over the weekend.

People arriving in the Northern Territory from a Queensland hotspot will no longer have to undertake supervised quarantine, and anyone in mandatory quarantine from a Queensland hotspot will be able to exit.

Western Australia has closed its border to all of Queensland until the eastern state goes 28 days without new local transmission cases.
