AN air search is underway for a group of five people feared lost in the remote Goldfields east of Kalgoorlie.
It is believed the party were travelling in a green Hyundai Excel sedan from Kalgoorlie to the Tjuntjuntjara Community and that their vehicle may have become bogged.
The area has experienced heavy rainfall in the last few days flooding and hazardous conditions has caused the closure of many roads in the region.
Police believe the party may have attempted to continue the journey on foot and may not have adequate food or water.
The occupants of the car are believed to be Rex Mitchell (41), Janice Stevens (43), Bruce Stevens (24), Shonna Jamieson (46) and an eight-year-old male child.
It is understood the group left Kalgoorlie sometime on Tuesday.
A search plane departed Kalgoorlie this morning with a Department of Fire and Emergency Services observer on board and police have notified surrounding pastoral stations.
