"And they'll be burning for months to come", Mr Morrison said. "If more is needed and the cost is higher, more will be provided".
"The fires have burned so hot and so fast that there has been significant mortality of animals in the trees, but there is such a big area now that is still on fire and still burning that we will probably never find the bodies", Nature Conservation Council ecologist Mark Graham said, as reported by news.com.au.
Though the impact of climate change on fire clouds is still a nascent field of research, scientists are concerned that climate change could make fire-induced storms more common, particularly as global warming drives more intense wildfires.
Fire authorities fear that two blazes in the states of New South Wales and Victoria could connect to create a mega blaze.
Nationwide, at least 25 people have been killed and 2,000 homes destroyed by the blazes.
Rain and cooler temperatures on Monday were bringing some relief to communities battling the fires.
Dozens of massive wildfires continue to burn in the east of the country.
The day's cooler, rainier weather was providing thousands of tired firefighters a "psychological and emotional" reprieve as they scrambled to strengthen containment lines around the blazes before temperatures rise again, said Shane Fitzsimmons, commissioner of the New South Wales Rural Fire Service.
Rod, Sean Stewart Charged with Criminal Battery
Footage from cameras at the hotel revealed that Sean and Rod Stewart were the "primary aggressors", according to the affidavit. The Stewarts have been requested to appear at the Palm Beach County Criminal Justice Complex on February 5.
But it also presents some real challenges when it comes to implementing tactical and strategic setbacks and other techniques to try to control these fires.
Nearly five million hectares (50,000 square kilometres) have been razed across New South Wales and more than 1.2 million hectares in Victoria since late September, officials said.
Numerous fires have become so big only sustained rainfall will put them out.
The Prime Minister of Australia, Scott Morrison, has faced severe backlash from the Australian public for failing to change the government's policies regarding climate change in the face of the bushfires. People there were quick to show their appreciation for the efforts Canada is making to help their country out.
"What about the people who are dead, prime minister?" one woman asked.
"Our focus remains on helping the people of Australia and keeping people safe in these unprecedented conditions", said Craig Leff, director of the Department of the Interior's Office of Wildland Fire.
While Australia is no stranger to yearly bushfires, the current one which has been raging since September started earlier and spread much further than previous ones, with fires blazing in every state. More than a thousand people were evacuated from the Victoria state town by two naval ships on Friday.
The environmental group Greenpeace said the relief funds announced by Morrison were "a drop in the ocean", given the widespread devastation from the fires.
