NSW Rural Fire fighters establish a backburn in Mangrove Mountain, New South Wales.
When asked today how long the volunteers were expected to work without pay and whether they should be professionalised, Mr Morrison said: "The fact is these crews - yes, they're exhausted, but they also want to be out there defending their communities".
As U.N. chief Antonio Guterres warned that the world would be "doomed" unless big emitters step up commitments, Australia's energy minister Angus Taylor said targets alone can not address climate change, no matter how ambitious. "Australia is playing our role as part of this challenge".
"I've lived all my life, pretty much, in Sydney, and the haze that has come from those fires, I know, has been", he said.
"I know as a Sydneysider ... It's been deeply troubling to families and kids, who've never seen this before".
Climate is a vexed political issue for Mr Morrison's Liberal party.
The prime minister said there was no direct link between any of the fires that have raged across Australia this year and his climate change policies. "We need to take practical steps at home, and be ambitious overseas", Mr Falinski said.
Australia has pledged to reduce emissions by 26 per cent below 2005 levels by 2030 as part of the Paris agreement.

The scientists also said that it could as well intensify the length of the fire season.
"It's great to hear that the prime minister can finally utter those words".
"The national government has to provide leadership", Turnbull said.
"We need to get on with the job of saving future generations and saving this planet".
However, for sometimes now, Sydney, where Morrison was born and raised, had been blanketed by toxic smoke pollution as the state continued to be ravaged by devastating bushfires.
Mr Morrison said Australia was reducing carbon emissions and getting results.
But independent analysts say that with emissions trending upwards, it looks unlikely that Australia will be able to achieve the target.
"We can only reduce emissions as fast as the deployment of commercially viable technology allows", Taylor told delegates.
Labor leader Anthony Albanese said the use of carryover credits should be banned. Fiji's economy minister Aiyaz Sayed Khaiyum said he hoped to see some "rationality" from Australia: "At the moment, we have seen they are far from sitting at the same table".
