Australian Defence Force troops have joined NSW police patrolling streets in Sydney's west and southwest to ensure COVID-19 health orders are being observed in the hotspots where the virus is surging.
About 300 ADF troops are reinforcing the efforts of police, patrolling and doorknocking to ensure people are complying with self-isolation and stay-at-home orders in eight Sydney local government areas.
The military support was requested by Police Commissioner Mick Fuller on Thursday when NSW reported a record 239 COVID cases - a figure that was matched again on Sunday.
Meanwhile, Strathfield South Public School, in Sydney's west is closed after a COVID-19 case in the school community.
The school's website says contact tracing and deep cleaning is underway while all staff and students must self-isolate until they receive further advice.
Sydney public transport services have been restored to a regular weekday timetable to avoid overcrowding as the construction industry resumes with some limitations, after a two-week hiatus.
Tradies from the eight worst affected local government areas in Sydney's west and southwest are still not allowed to work or leave their area.
However, construction in other areas can resume on sites and in homes where there are no residents.
Tradies and cleaners can attend domestic jobs if there is no contact, while there is a cap of two masked workers indoors and five people outdoors.
Elective surgery has been cancelled in Greater Sydney hospitals but remains scheduled on the Central Coast and the Illawarra.
Meanwhile, a nurse has been sacked for giving soon-to-be expired doses of Pfizer vaccine to her daughter and two nephews, instead of discarding the shots.
Christine, was working as a nurse at Health Care Australia - one of the contractors hired by the Commonwealth to administer the vaccine in aged care facilities.
She's told Sydney Radio 2GB that last week she was sacked after using three leftover doses that would otherwise been discarded, on her eligible family members.
"I believe I did the right thing. I mean part of the code of conduct is to be smart and cost effective," she said on Monday.
Meanwhile, Premier Gladys Berejiklian says half a million NSW residents could be vaccinated against COVID-19 every week.
The premier is hoping August will be a record month for vaccinations.
The virus is continuing to spread across Sydney households, around workplaces and into aged care facilities.
There are 222 COVID-19 cases in hospital in NSW. Of these, 54 people are in intensive care, 25 of them requiring ventilation.
NSW Health's Dr Jeremy McAnulty said there were multiple aged care facilities across Sydney where staff and residents had been infected including nine residents at an aged care facility in Summer Hill in the city's inner west.
