Police have “grave concerns” for seven people who have gone missing on a journey to an Indigenous community in outback WA.

Record rainfall has seen  Australia’s largest sheep station under water and the storm has closed Perth’s main road to the rest of the country. Floodwaters have also cut access to the Trans-Australian Railway line.

Both the road and rail routes are  expected to remain closed for several days.

WAPolice Inspector Mick Kelly told C9 News  two men, one woman and four children aged between 12 and 17 were driving from Boulder to Tjuntjuntjara, but had not arrived.

“Concerns are held due to the fact we have had severe weather and rain and more has been forecasted over the next 24 hours,” Inspector Kelly said.

“We have heard from the community of Tjuntjuntjara that they have not arrived safely.

“We are unsure of what food and water resources they have onboard.

“We do hold grave concerns for their welfare.”

The Tjuntjuntjara community lies about 650km north-east of Kalgoorlie.

Inspector Kelly said he hoped they had stayed near their vehicles, a Toyota Landcruiser registration A683 and a Mitsubishi Triton registration KBC8881.

In the past 48 hours, hundreds of millimetres of rain has soaked the region.
