And yet in NSW no "State of Emergency" required as the provisions contained therein (VIC) are available for general use regarding matters of public health without any further formality.
"The New South Wales Government doesn't even need to declare a state of emergency to deal with a public health issue.
The state's Health Minister, Brad Hazzard, can make any direction he needs to reduce or remove the risk of COVID-19 in an area, to segregate or isolate people, or to block access to any part of NSW."
