The PM has also sat for a pre-recorded interview with 60 Minutes, which has just aired.
That interview was far less fiery than the ABC's, but Mr Morrison didn't shy away from the seriousness of the situation, which he described as one of the toughest since WWII.
In fact, he said the country is once again at war – but this time with an enemy that’s proving hard to defeat.
“We are in a war against this virus and all Australians are enlisted to do the right thing,” Mr Morrison said.
Confirmed cases of coronavirus continue to soar across the country, despite increasingly strict social distancing measures designed to slow the spread.
When asked how many cases Australia could ultimately see, Mr Morrison said: “Nobody knows.”
“What we can provide certainty of is that if somebody finds himself in a position where they have lost their job, I have doubled the jobseeker payment,” he added.
“If a business needs to get from now to the end of this crisis, which we think is at least six months, we provide up to $100,000 in grants to help them get there.
“That's why we are ensuring people can break open and access their own superannuation safes.
“These are designed to help. What I cannot do is forecast an unforecastable situation.”
One thing the PM is sure of is the economic impact the pandemic will have.
“The economy will be significantly battered by this in a way that we have not seen, in my lifetime,” Mr Morrison said.
He appealed for Australians to continue adhering to strict social distancing measures imposed by his government, warning that failure to do so will see more restrictions rolled out.
“People are told to self-isolate for 14 days when they come back (from overseas). People are told to keep 1.5m distance. Venues are told to have an average of four metres for each person.
“This needs to be observed, otherwise very draconian measures need to be enforced that might otherwise have been unnecessary.”
The PM will hold a live press conference at 9pm.
