"We have many challenges in this country at the moment, but we will see our economy strengthen, we will see Australians kept safe - whether it's from COVID or the many other threats that this nation faces, and we will guarantee the essential services that Australians rely on."

The aged care royal commission will get a more than 3 month reporting extension, to February 26 next year.

Scott Morrison says it makes sense for people living in communities across the NSW-Victorian border to stay put. He says people near the border should exercise good judgement and common sense.

The PM stresses his position on border closures hasn't changed. He says "Victoria has effectively self-isolated." He says people should be able to move between other states and territories, provided no further outbreaks pop up.

Scott Morrison: "This is about Victoria isolating itself not other states shutting [themselves] off from Victoria. There's a key difference in that."

Scott Morrison says the job for Melburnians is "to tough it out." He says it will be tough but he thanks people in Melbourne for their efforts. The PM says all Australians have to do their part.
