Canberra: An investigation into Australia's catastrophic wildfire season on Friday recommended greater efforts to forecast the impacts of climate change on specific parts of the country, warning fire behaviour was becoming more extreme.
The Royal Commission into National Natural Disaster Arrangements began in February while wildfires were ravaging vast swathes of the nation's southeast in a fire season that is now known as Black Summer.
The fires killed at least 33 people including 10 firefighters, destroyed more than 3,000 hones, razed 19 million hectares (47 million acres) and displaced thousands of residents.

The Royal Commission, which is the country's highest form of investigation, said that smoke that blanketed much of Australia, including major cities, had contributed to hundreds of deaths.
The commission's 578-page report, with 387 pages of appendices, made 80 recommendations, including for greater harmonisation of data across Australia on climate and disaster risks.
The report said federal and state governments should produce "downscaled" climate projections, and agree on climate trajectories and timelines.
Discrepancies between states' fire hazard mapping methods "make it difficult to measure risk at a national scale or to undertake comparative risk between regions".
"Improving weather forecasting and climate projection capability is important to improve the ability to predict or estimate the likelihood of extreme" wildfires, the report said, citing the Commonwealth Scientific and Industrial Research Organisation, an Australian government agency.
