NSW Health is warning there still may be transmission among people who have unrecognised infections with mild or no symptoms.

“Though restrictions have been eased in NSW, we must continue to be vigilant. NSW Health continues to ask everyone to continue to come forward immediately for testing if they have even the mildest symptoms,” it said in a statement on Wednesday.

Meanwhile, retailers are calling for a further easing of COVID-19 restrictions to encourage people to get into the spirit of Christmas shopping.

Business NSW says retailers need to be given a chance to capitalise on Christmas spending with a relaxation of restrictions on their premises.

Retailers must now adhere to the one person per four square metre rule, unless they are a supermarket or shop that mostly sells food.

“With Christmas shopping in full swing and no community transmissions in NSW for some time, we need to give retailers a break in the lead up to Christmas,” Business NSW chief executive Nola Watson said.

While cafes can have one person per two square metres, clothing retailers and bookshops are more limited, Ms Watson says.

“It goes without saying what a difficult year it has been for the retail sector, and here is an opportunity to provide them with some relief, so long as they operate in a COVID-safe way.
