A dual-cab light vehicle with a single occupant was travelling to a rig camp location on a public access road. It was night time and water was flowing over the crossings. The driver entered a crossing where height of the water was unknown and there were no flood markers in place. Whilst traversing the crossing, the depth of the water and the strength of the current moved the vehicle sideways. The vehicle came to rest on submerged debris. The driver phoned for help and was retrieved from the vehicle by the rig crew. No injuries were sustained by the driver or the rescue party.
