The Morrison government has set aside another $40 billion to spend on measures such as purchasing emergency medical supplies, boosting the front-line health response, and another round of economic assistance as the coronavirus crisis intensifies in the months ahead.

The extra money was set aside in budget bills that were rushed through a special sitting of Parliament on Monday after Prime Minister Scott Morrison used a speech to invoke the Great Depression, urge people of faith to pray, and warn that 2020 for many "will be the toughest year of our lives".
