People are being asked to wear a mask if:

* social distancing is impossible, for example on public transport;

* you are a public-facing employee, like a bartender or supermarket worker;

* you are attending a place of worship;

* you reside in an area of community transmission or near a COVID-19 cluster;

* you are a person vulnerable to COVID-19 due to your age or underlying health issues.

Woolworths and some other food retailers, like Harris Farm Markets, are already encouraging customers to wear masks while instore to protect their staff.

Social distancing remains the key method by which people can avoid catching or spreading the disease in the state, the government says.
