New South Wales reports 145 new cases of COVID-19

New South Wales has recorded 145 new cases of COVID-19 in its community - 51 of which were infectious in the community before they tested positive.

Premier Gladys Berejiklian thanked the public for coming forward and getting tested saying more than 98,000 people "took the time and effort" to go and get a test.

However, she reiterated how crucial it was for people to abide by the restrictions if they wanted to keep themselves and others safe.

"It's really important for people not to leave home unless they really have to. Do not mingle with other households. We need to make sure everyone appreciates how important it is not to mix."

Chief health officer Dr. Kerry Chant said if people do have to leave the house, they should assume they could come into contact with someone who is carrying the virus.

"Please make sure you're wearing your mask appropriately and staying at least 1.5 metres apart."

Both Chant and Berejiklian said vaccination is the best way to protect people, and the wider community against the virus.
