NSW Health Minister Brad Hazzard encouraged people to heed advice on social distancing, amid the rising number of infections.
“The problem is just over the horizon on the basis of the numbers that we’re now seeing,” he said.
“Particularly here in New South Wales, they are showing a substantial increase.
“We will all remember the numbers in the last few days, they’ve effectively doubled just in the last week.
“Save yourself and save your family. Listen to the messages that are coming out, not just from Government officials but from doctors.”
