New South Wales has broken its daily COVID-19 cases record again, recording 390 community cases and two deaths on Friday.
Of these new cases, 250 are still under investigation - almost two-thirds - while the other 140 are linked to a known case or cluster. Fifty-eight people were infectious in the community, and the isolation status of another 191 is being investigated.
The two deaths were in an unvaccinated woman in her 40s who died at home, and a man in his late 90s who was in palliative care and had received the jab. The number of coronavirus-related deaths since the beginning of the current outbreak now stands at 38.
As it stands, 391 COVID-19 cases are in hospital, with 63 of these in intensive care and 30 requiring ventilation.
Since the start of the current outbreak on June 16, 6874 locally acquired cases have been detected in the state.
Elsewhere Victoria recorded another 15 cases, seven of which were in the community while infectious. Four of these cases are causing health officials some consternation as they have not yet been linked to an existing cluster.
Victorian Premier Daniel Andrews unveiled a plan to get "1 million jabs in 1 million arms" over the next five weeks, and is aiming to have 60 percent of Victorians vaccinated by the end of September.
Queensland recorded seven new local cases on Friday, though all were in home quarantine and linked to the Indooroopilly State High School cluster.
Premier Annastacia Palaszczuk said she was "very concerned" by spread of the Delta COVID-19 variant from New South Wales, where it's rampant.
"From Queensland's point of view, we are very concerned about how the clusters are continuing to expand," Ms Palaszczuk said.
"I think we would need to hear very clearly from New South Wales what their clear plan is for containment. The last thing we want to see is this virus spread north, the virus spread south, and spread across the nation.
"So, it's absolutely imperative that New South Wales contains this virus."
