Jan Reynolds lost her house in Numbugga, outside Bega, in August last year, after strong winds caused a fire that came with little warning.

Driving away with her driveway surrounded by burning bush, Ms Reynolds got out of the car and moved a fallen tree that blocked the car's path.

"This is what adrenaline does," Ms Reynolds said.

The progressive activist group is funding television advertisements and helping launch the group on Thursday called Bushfire Survivors for Climate Action.

Ms Reynolds' face and burnt house will be beamed through lounge rooms across the country starting February 19, in a campaign that she hopes will make both politicians and average Australians connect extreme weather events with climate change.

She will also be part of a group taking the message to parliament house on Thursday, asking politicians to support policies for renewable energy.

While Ms Reynolds had a bushfire plan, she didn't expect to need to enact it in August.

"I've been through lots of fires before in the Blue Mountains where I used to live, and we fought them, because there wasn't that wind. If you read about the winds, the heating up of the atmosphere is creating these massive winds."

In the months since the fire, Ms Reynolds has relocated to Bega and hopes in April to start the clean up of her block before rebuilding.

Chris Mills' house on Burrendong Street in Duffy burned to the ground in Canberra's 2003 bushfires. He is also part of the campaign, and said he put his hand up because of his "profoundly disturbing experience".

"Climate change is an existential threat to humanity. It's like a train that's going over a cliff and we need to take every opportunity to get people to take notice," he said.

Mr Mills left Canberra in 2004 and now lives in Mallacoota in Victoria, where he still faces fire risk each year. Like Ms Reynolds, he feels the risk of fire is increasing due to climate change, and wants to see action.
