The cost of repairs to roads, drainage and water supply systems caused by flooding across WA is set run into the millions of dollars, the Federal Government has revealed.
Announcing more disaster relief for affected communities, federal justice minister Michael Keenan has confirmed 17 local government area had now been flooded.
Some areas of WA have received almost 500 millimetres of rain in just 24 hours, with residents saying they had never experienced flooding like it.
"Individuals and families, farmers, small business owners and councils affected by this widespread flooding will now have access to assistance to help them recover and get back on their feet as soon as possible," Mr Keenan said.
The funding will help communities with clean-up and recovery costs, while also providing for the restoration or replacement of public assets damaged as a result of the flooding.
The disaster relief, under a jointly-funded Commonwealth and state arrangements, is now open to the Shires of Ashburton, Broome, Derby-West Kimberley, East Pilbara, Halls Creek, Menzies Creek and Wyndham-East Kimberley.
Following earlier storms, residents in Coolgardie, Cue, Leonora, Meekatharra, Mount Magnet, Murchison, Sandstone, Wiluna, Yalgoo and the City of Kalgoorlie-Boulder are already receiving assistance.
