The head of the government's emergency management agency has warned the use of the defence force to assist with natural disasters may not be sustainable in the future.
National Emergency Management Agency director-general Joe Buffone told a parliamentary inquiry into the country's disaster resilience the increasing number of events like bushfires and floods could impact how ADF personnel were deployed to help in the clean up.
Mr Buffone said with climate change contributing to natural disasters, there would be a greater strain on the ADF to assist with recovery efforts.
