The federal government will put $76 million into emergency mental health services for bushfire-affected communities, with Prime Minister Scott Morrison pointing to the widespread trauma caused by the unprecedented crisis.

The "initial" mental health funding will go to counselling sessions, extra psychological treatment under Medicare, expanded access to telehealth remote counselling, specialist trauma care for emergency services personnel, local community wellbeing programs and Headspace youth centres in significantly impacted communities.

“These bushfires have been unprecedented in their scale, coverage and duration. They have caused tragic loss of life and physical damage, that have scarred our landscape. But as I have witnessed in connecting with people on the ground in fire-affected communities, they have also taken a traumatic emotional toll on our people," said Mr Morrison.

"We need to ensure the trauma and mental health needs of our people are supported in a way like we never have before."
