The progressive party is also pushing for incentives for states to ditch stamp duty paid on house and car insurance
Sky-high insurance costs have become a talking point ahead of a federal election campaign dominated by hip pocket pain, with the opposition leader, Peter Dutton, floating a plan to break up big insurers earlier in the week.
The latest estimates from the Actuaries Institute found the median insurance premium had increased nine per cent in the year to August 2024, and 30 per cent for those in areas at risk of floods or cyclones.
Insurers have been pushing up prices because of more frequent natural disasters under a warming climate, which jacks up reinsurance costs.
High costs of building and repairs have further kept upwards pressure on insurance premiums.
Greens Deputy Leader Mehreen Faruqi said coal and gas companies should "pick up the tab" and contribute to an expanded reinsurance pool and the $1 billion federal fund for disaster resilience and risk reduction.
"Families, renters and retirees should not have to pay skyrocketing insurance premiums for a climate crisis they did not cause," she said.
Greater transparency around insurance pricing and a free national disaster risk map and database were also suggested by the party.
Australia's patchwork of disaster risk information was highlighted in a Australian Housing and Urban Research Institute study released on Wednesday.
The research additionally found private renters were often overlooked in the post-disaster policy response, and likely to face higher prices for housing in the wake of floods and fires as damaged homes were removed from already-tight markets.
RMIT University's Annette Kroen, who led the research, said renters were more likely to be lower-income households and living in older, poorly-maintained homes.
"There's often also the insurance cover, renters may not be able to afford insurance or when renting a property you might not think about getting insurance," Dr Kroen told AAP.
And renters were typically left out of government response measures, she explained.
This includes waived time limits on caravans on properties, a measure intended to keep residents in the community while homes are rebuilt.
Grants and financial assistance made available to landlords in disasters should come with stipulations to cap rent increases and offering the home back to the original tenant, she said.
