The number of confirmed coronavirus cases in NSW has topped the 1000 mark and, for the first time, children under 10 have been infected.
Premier Gladys Berejiklian and the state's chief health officer Dr Kerry Chant provided an update on Wednesday morning.
An additional 211 people have tested positive in the last 24-hour period, taking the total number to 1029.
Of these, 500 were overseas acquired and 176 were locally acquired or a were a contact of a confirmed case.
A two-months-old boy and a girl, 7, are the first cases under the age of 10. The previous youngest was 12.
Both children were tested following close contact with a confirmed adult case. They have minimal symptoms and are isolated at home.
The seven year-old girl did not attend school while symptomatic.
There are currently 10 COVID-19 cases in NSW intensive care units and, of those cases, only four require ventilators at this stage.
There has been no increases in cases diagnosed in NSW from the cruise ship Ruby Princess. The present number of confirmed cases is 105 in NSW, revised down from 107.
Ms Berejiklian said the strong message was that if people were told to self isolate, or were aware they needed to self isolate, they would be followed up.
"We need to make sure we contain the spread as much as possible at this stage of the virus," she said.
"We are stepping up on these checks, we are stepping up on enforcement," she said.
"The vast majority do the right thing, but Crime Stoppers has calls increasing day by day from people rightly dobbing in someone who they know should be self isolating.
"I also want to stress again that this is a time when all of us have to step up.
"While we have enforcement there, while we have compliance and checks, we also need to make sure the community does the right thing by yourself, your family and others."
Ms Berejiklian said, the majority of cases were still acquired overseas, which meant, at this critical stage, "we are maintaining some control over the virus".
Ms Berejiklian said Service NSW would employ 1000 new staff as part of a move by the state government to improve communication on the issue.
