The commission is taking submissions from all members of the public, community groups and business on the preparedness, co-ordination, response to and recovery from the 2019-2020 bushfires - the worst bushfire season in Australia's history.

"I witnessed first-hand the devastating impact these fires had on our local communities," federal Member for Calare Andrew Gee said.

"However, I was privileged to see the best of Australia during those fires.

"I will never forget the courage, determination and commitment of our firies, emergency services personnel and volunteers. They have many suggestions on the lessons that can be learned from this emergency and I think it's really important that the commission hears their stories.

"They were there, and they know what went right and what can be improved upon. The need for hazard reduction burns and the management of our national parks are examples of issues our firies have raised with me as needing attention.

"One thing we do know is that Australia will always have bushfires and we need to make sure that next time we face this type of emergency we are better prepared."

Submissions can be lodged online at the National Natural Disaster Arrangements' website or by calling 1800 909 826.

Mr Gee said COVID-19 restrictions meant the commission would not be travelling, "so this is the best way to have our voices heard".
