Pilbara communities affected by flooding after heavy rainfall in June are eligible for financial help.
Roebourne and Karratha recorded their second wettest day on record, after more than 200 millimetres fell in a 24-hour period, while strong winds caused damage in Port Hedland.
The Pilbara's four shires are eligible for assistance under the state and federal governments' Natural Disaster Relief and Recovery Arrangements.
The assistance helps with clean-up costs, personal hardship grants and freight and interest rate subsidies.
The program's Graeme Capper says at this stage it appears more than $1 million will be claimed by local governments to fix damaged roads.
"We have heard nothing else, in cases for WANDRAA [Western Australian Natural Disaster Relief Arrangements] there other areas we give assistance to or where assistance may be available and that's for people, personal individuals, small businesses and primary producers but in this case we haven't heard anything to that end," he said.
"The main damage caused by this tropical low and flooding was actually on the road infrastructure for the local governments and of course the State Government itself.
"We have got details, so far it's going to be in the region of one-and-a-half million dollars to repair the local road infrastructure in the shires affected by this flooding."
