Scott Morrison has joined mourners in an online memorial to honour fire and emergency workers killed in the line of duty.
The service recognised 14 men killed in the past year, many of whom died fighting the Black Summer bushfires.
The prime minister recognised their courage, sacrifice and willingness to protect communities.
He described last summer’s bushfires as among the most devastating in Australian history.
“A time when fire turned day into night and turned the sky into an angry red. When tens of thousands of volunteers from all walks of life stood together to make a difference,” Mr Morrison said.
“They came from our cities and our towns, even from across the seas. And we particularly remember our American friends whose names are now included amongst our most honoured.”
The names of those killed will be etched on a memorial wall on the shores of Lake Burley Griffin in Canberra.
Bushfire survivors have descended on Canberra to demand strong action on climate change, ahead of the royal commission’s final report being handed to the federal government.
The survivors will meet with Opposition Leader Anthony Albanese and Labor MP Kristy McBain, whose NSW seat of Eden-Monaro was devastated by the fires.
They will also speak to other federal politicians including independent Helen Haines, urging them to pursue net zero emissions and embrace renewable energy.
“We know that the bushfires that destroyed our homes and devastated our communities were supercharged by climate change, which is driven by the burning of coal, oil, and gas,” spokeswoman Jan Harris said.
“The bushfire royal commission must tackle the root cause of why last summer’s fires were so bad, and recommend urgent climate action to keep Australians safe from worsening bushfires.
“The whole process will have been in vain if it doesn’t follow up its acknowledgement of climate change’s role in the fires with action.”
The bushfires raged across 10 million hectares, took 33 lives and destroyed 10,000 homes and other structures.
More than 80,000 head of livestock were killed and millions of native plants and animals were lost.
The royal commission has examined Australia’s preparedness, response and recovery from disasters, and looked at ways to improve resilience and adapt to climate change.
It took more than 1700 submissions, with public hearings continuing until September.
How best to declare a national emergency during catastrophic bushfires and other natural disasters is expected to be among a raft of recommendations in its final report.
The commission will also outline how to make the role of the Australian Defence Force during bushfires clearer.
The report is expected to contain recommendations around wildlife management, mental health, recovery funding arrangements, land management and the use of emergency warnings.
The commission has already suggested a body similar to the national cabinet, set up to deal with coronavirus, be tasked with managing the response to bushfires.
