Police hold concerns for the welfare of a 51-year-old man, after he went missing in the Stirling Ranges.
Matthew Dwyer - a professional photographer who frequents the area - has not been able to be located since Wednesday morning.
At around 7.30, his keys and backpack were found on Bluff Knoll by a member of the public, while his camper-van was found in the car park.
He is described as approximately 180cm tall, with a slim build and grey balding hair.
It is believed he may be wearing long pants and a blue top, possibly with a jumper.
An Australian Maritime Safety Authority Search and Rescue Jet conducted a search of the area overnight, and will today continue with a police helicopter and emergency services.
Anyone who sights Mr Dwyer or has any information regarding his whereabouts is asked to call police immediately on 131 444.
