“Stop it. It’s not sensible, it’s not helpful and I’ve got to say, it’s been one of the most disappointing things I’ve seen in Australian behavior in response to this crisis. That is not who we are as a people,” he said.

Morrison, who has faced criticism from some doctors for not imposing stricter social isolation measures, also announced extended restrictions on mass gatherings to all indoor events with more than 100 people, however, he insisted that schools would remain open to ensure hospitals were properly staffed.

“This is a once-in-100 year type event, we haven’t seen this sort of thing in Australia since the end of the first World War, but together we are of course up to this challenge,” he said.

Morrison warned the disruptions could continue for “at least six months … it could be much longer.”
