A father and son, Ray and James Dempsey, were found dead in Meekathara, WA after being reported missing since Friday.

The ages of the deceased were 66 and 33, respectively, and both were from Perth.

Their disappearance sparked a three-day search operation with land and air resources, including State Emergency Service and skilled trackers.

The duo's abandoned campsite was located on a remote station, but the timeline of their disappearance remains unclear.

Authorities are preparing a report for the coroner to investigate the mysterious circumstances surrounding their deaths.
