Disaster assistance will be provided to people, small businesses and primary producers affected by flooding in Western Australia's Kimberley and East Pilbara regions last month.
The assistance, for five local government areas, is being provided through the jointly-funded Commonwealth-State Natural Disaster Relief and Recovery Arrangements.
Federal minister Angus Taylor said the tropical low brought heavy rainfall and strong winds in excess of 100km/h.
"Some communities were left isolated and many of these roads had also suffered previous damage from the recent tropical cyclones Hilda and Joyce," he said.
"This activation of the NDRRA will ensure funding is available to help affected communities and restore damaged public infrastructure, such as roads."
