Infections dropping, free pre-school

The number of new coronavirus cases in NSW continues to decline with 39 in the past 24 hours, taking the state's total to 2,773.

"This is only working because everyone is doing the right thing. Over this Easter long weekend, respect the rules," NSW Premier Gladys Berejiklian said at her morning press conference.

She also announced that to help struggling families through the pandemic, the NSW Government would provide free pre-school for the next six months at a cost of around $50 million.

"We are pleased to do this, we know household budgets are under pressure," she said.

Thirty detectives dressed in personal protective equipment boarded the ship at Port Kembla, near Wollongong, to conduct interviews with high-priority witnesses and seize evidence.

Strikeforce Bast is investigating whether the ship's operator downplayed the number of potential coronavirus cases on board before 2,700 passengers disembarked at Circular Quay.

Police have urged anyone who experienced symptoms or was offered medical advice during the ship's voyage to contact Crime Stoppers.

City patients could be treated in the country

Patients in Sydney could be treated at country hospitals if regional cases of COVID-19 continue to drop, the Western NSW Local Health District has announced.

Chief executive Scott McLachlan said if Sydney hospitals became overloaded, regional New South Wales could step in.

"I do expect that in metropolitan Sydney, and other metropolitan areas, we will see some increased activity [but] we know in the bush there's some protection, with distance and other things — our hospitals absolutely can play a role ... for people outside our region," he said.

Just over 40 cases have been confirmed in the western region of NSW, which takes in Mudgee and Dubbo, and 20 people have already recovered.
