COVID-19: New South Wales records 141 new community cases, two deaths

New South Wales has recorded 141 new cases of COVID-19 in the community while two infected women have died - one of whom was in her 30s, state Premier Gladys Berejiklian says.

Of the 141 new infections, 62 were infectious while in the community, Berejiklian told a news briefing on Sunday. 

That figure has stayed stubbornly high even after four weeks of a lockdown in Sydney, which is now expected to be extended beyond July 30.

Two women - one in her 30s and the other in her 70s - have become the seventh and eighth victims of the latest COVID-19 outbreak.

"If anybody thinks this is a disease just affecting older people, please think again," Berejiklian said.

NSW is grappling to control its escalating COVID-19 outbreak - largely being driven by the highly contagious Delta variant of the virus.

And there are fears of a wave of new infections after thousands of people joined an anti-lockdown protest on Saturday.

"In relation to yesterday's protests, can I say how absolutely disgusted I was. It broke my heart," Berejiklian said.
