The NSW hospital system is far from buckling under the weight of COVID-19 cases despite a new record number of daily infections, the state's health minister says.
NSW reported 830 new locally acquired cases of COVID-19 in the 24 hours to 8pm on Saturday, another daily infection record, as well as three deaths.
The deaths were of a man in his 60s, a man in his 70s and a woman in her 80s, none of them fully vaccinated. The fatalities take the toll for the current outbreak to 71.
All of NSW is currently in lockdown and police have ramped up enforcement of restrictions as authorities battle to contain the spread of the Delta strain.
Lockdown settings will remain in place in regional NSW until at least August 28 and in Greater Sydney until at least September 30.
There are currently 94 COVID-19 patients in intensive care beds in NSW, with 31 ventilated.
Yet as case numbers mount and elimination of COVID-19 in NSW becomes unfeasible, Health Minister Brad Hazzard said the state's health system retained plenty of excess capacity to handle sick patients.
NSW Health said in a statement on Sunday that it currently manages about 500 intensive care unit beds, with a surge capacity of about 2000 when required.
There were also enough ventilators for each intensive care bed - about 2000.
Vaccinations - even with one dose - were also helping keep infected NSW residents out of hospital and intensive care. As of Friday, more than 57 per cent of the eligible population had received at least one vaccine dose and almost 31 per cent are fully vaccinated.
The government has flagged easing some restrictions once NSW reaches six million vaccinations, and significant freedoms at 70 and 80 per cent vaccination coverage.
"We have less than 100 people in ICU and quadrupled our ICU capacity last year ... from about 500 ventilators up to a few thousand," Mr Hazzard said.
"I've not had any advice at all at this stage that we are at a point of being concerned."
However this situation was predicated upon daily infection rates in NSW not jumping exponentially in the coming days and weeks.
Of the 830 cases in the 24 hours to 8pm on Saturday, the isolation status of almost 700 remains under investigation.
There were 36 new COVID-19 cases recorded in the Western NSW local health district.
Premier Gladys Berejiklian said on Saturday she'd noticed a "change in attitude" from her interstate counterparts and an acceptance "Delta is here".
Mr Hazzard reiterated those comments on Sunday, saying the Delta variant would inevitably breach every defence in the world. As such, getting vaccinated was the only long-term solution.
"Some states have relied on distance, so if you have a long highway across the desert, you can put a gate across it and say that's it," Mr Hazzard said in a reference to Western Australia.
"I hope we will be able to get the vaccination rates up in those jurisdictions in Australia which have not had the exposure to the virus to a great degree.
"That is more challenging because those communities have been lulled into a false sense of security."
He thanked residents of the 12 western and southwest Sydney council areas of concern for "voting with their feet and getting vaccinated".
Meanwhile, a concerted NSW Police operation to smother a planned anti-lockdown protest on Saturday appeared to be effective, with numbers a fraction of last month's rally.
Some 1500 police were involved in patrolling approaches to the CBD. NSW Police arrested 47 people and fined more than 260 in relation to protests across the state.
This included five people involved in an anti-lockdown protest in Albury on the NSW-Victoria border.
