The premier of Australia's most populous state of NSW, Dominic Perrottet, addressed the media on Thursday to confirm masks will be mandated for inside areas and density limits would also be imposed.

As of midnight tonight, we will be requiring that masks are worn in indoor settings.

We are encouraging people, particularly over the holiday period, if you can work from home, please work from home.

In addition to that, we're encouraging people not to mingle and when you're out and out at a restaurant or cafe and a pub or a club, please where possible don't mingle.
