There are fears for a camper, missing in rugged bushland in Victoria's high country.
Police will resume their search in the morning for Steven, an experienced camper and dirt bike rider who hasn't been seen for over 24 hours.
Authorities say the 58-year-old always keeps in touch with family while he's away and the fact they haven't heard from him in so long is a major concern.

Victoria Police have not released Steven's surname but have shared a photo of him.
The 58-year-old was last seen wearing light-coloured motorcycle clothing and a black helmet with green stripes when he left a campsite at Skipworth Reserve in Kevington, about a three hour drive north-east of Melbourne.
He told his partner he was going to ride the tracks around the nearby Mount Terrible area at 2pm Friday afternoon.
Police were searching around the area on Saturday with the help of the airwing but conditions weren't ideal.
There are concerns Steven may be injured and unable to call for help.
The search will continue today but authorities are asking for anyone who may have been in the area and spotted something to call the Benalla Police Station.
