NSW Police Commissioner Mick Fuller has revealed the state's tough coronavirus enforcement laws are set to expire in 90 days, and that he will not seek to extend them.

The news comes as Premier Gladys Berejiklian praised people for helping flatten the COVID-19 curve in Australia's worst-affected state.

There has been 116 new coronavirus infections in NSW in the 24 hours to 8:00pm Wednesday, bringing the state's total to 2,298.

Commissioner Fuller said the new powers which permit police to fine people for disobeying isolation orders had an end date.

"When is the turn-off period for these health orders? It is 90 days," he said.

"I certainly won't be seeking an extension, people will have gotten the message by then, hopefully."

People in NSW are living under Australia's toughest coronavirus restrictions and police have the power to deliver on-the-spot fines of $1,000 to individuals who breach those rules.

The maximum penalty that can be given by a court is $11,000 and six months in jail.

The only lawful reasons to leave the house are to work, study, to shop for food or other essential items, access medical care or exercise alone or with one other person.

Beyond this, the NSW Government has provided several reasons which would "excuse" someone for being outside which includes fleeing an unsafe home or donating blood.

The state's coronavirus death toll remains at 10.

More than 108,000 people have been tested for COVID-19 in NSW.

"The acceleration of cases in New South Wales isn't growing, which is a good thing," Ms Berejiklian said.

"So, we know that we're having some level of success in reducing the spread."

Australia's coronavirus "lockdown" is less strict than other countries'.

In Lombardy, the worst-affected Italian province, all outdoor physical activity is banned, while in Wuhan, the Chinese city where the virus originated, only one person from each household was permitted to go outside every two days at the height of the crisis.

Commissioner Fuller said three fines were issued in the past 24 hours and he was personally reviewing every ticket and if it appeared unreasonable, it would be withdrawn immediately.

In response to concerns about the ability to exercise in public, he said police were committed to taking a "sensible approach".

"I get it, and we want people to be able to stay fit and physically and psychologically healthy," he said.

"But, of course, if I said it's ok to sit on a park bench, then everyone is going to go to the park. And we're going to end up back where we started."

On Wednesday, a 39-year-old man was fined for washing windscreens at a set of traffic lights and a 59-year-old man was fined for drinking in a park with three other friends and refusing to leave.

Commissioner Fuller also revealed an external team of infection specialists employed by Australian Border Force would soon board the eight cruise ships sitting off the NSW coast.

He said the experts would provide an independent health assessment of the 8,500 crew members on the ships.

"If the crew are fit and healthy then I have no hesitation asking Mr Dutton and Border Force to enforce the orders to leave our waters," he said.

The Department of Home Affairs has ordered all cruise ships to leave Australian waters but Commissioner Fuller said that decision was being appealed.
