A man from Goulburn Mulwaree is among the deaths to be reported in what's described as one of the deadliest days in the COVID-19 pandemic.
Chief health officer Kerry Chant said 36 people had died in NSW in the 24 hours to 8pm Monday.
Among them was a man, aged in his nineties, from the Goulburn Mulwaree local government area.
A man aged in his seventies also passed away in the Bega Valley Shire.
In his mid-morning conference, Premier Dominic Perrottet extended his condolences to the families of those who had lost their lives to COVID-19 in what had been a "very difficult day."
He said behind every number was a loved one who had passed away or a person in ICU or hospital "going through a very difficult time."

Anyone who tests positive using a RAT is now required to register their result with Service NSW via the website or app under a Public Health Order.
Registering your RAT result enables NSW Health to provide you with advice on self-isolation and managing COVID-19 symptoms at home, to connect high risk people to clinical care services and to help inform the ongoing public health response.
