A royal commission into Australia's devastating bushfires will look at the impact of climate change, the operational response at a state and local level and the role of the federal government.
Prime Minister Scott Morrison flagged the inquiry as he conceded there were things he could have handled better at a personal level.
Mr Morrison has faced weeks of criticism - as the bushfires death toll rose to 28 - starting with his decision to take his family on a holiday to Hawaii and flowing through to his fire-ground visits during which he was met with anger and frustration.
The latest plank in the federal response is a $76 million mental health plan to provide support to firefighters and residents in affected communities, but more announcements are expected in coming weeks including a royal commission and further support for small business.
"There are things I could have handled on the ground much better," Mr Morrison told ABC TV on Sunday.
"These are sensitive, emotional environments.
"Prime ministers are flesh and blood too in how they engage with these people.
"When I went there I went there in good faith, with Jenny on occasions, to provide what consolation I could. They're very strained environments ... you would do things differently and learn from every event but the important thing is the actions we have taken."
He said in hindsight he would not have taken his family for a holiday to Hawaii, despite being defensive about it in a radio interview at the time.
His original intention was to holiday, as was routine for his family, on the NSW south coast.
"One of the great difficulties in any job ... is balancing your work and family responsibilities," he said.
Mr Morrison said the scale of the bushfires was "unprecedented" and had created a situation in which Australians were demanding a greater response from the federal government than had been provided in the past.
"That was not something that was recommended going into this fire season," he said.
"There is a very new appetite, a very new expectation."
Meeting this new expectation could require federal legislation and new agreements with state and territory governments.
As well, details of a royal commission would be put to the premiers and federal cabinet in coming weeks, he said.
"I think Australians have a very reasonable expectation that any commission of inquiry, royal commission, would need to cover the full gamut of issues."
Facing criticism that federal authorities sat on their hands earlier in the bushfire season, Mr Morrison said his government had acted on all recommendations put to it.
He said the government's climate policy would continue to "evolve", including its emissions target, and adaptation and resilience measures.
This work would include looking at building more dams, native vegetation and land clearing rules and ensuring homes are built in areas where climate risk has been assessed.
