UPDATE: Police believe a body found in Monbulk this afternoon is that of a man missing in the area for three days.

Victoria Police spokeswoman Belinda Batty said a body was found just after noon around Pound Creek Track.

She said the body, yet to be formally identified, was believed to that of missing man John McKague, 24, who has been missing since Saturday.

Police, the SES and Parks Victoria searched the Dandenong Ranges National Park today after reports Mr McKague may have been in the Sherbrooke Falls area.

The death is not being treated as suspicious.

Police will prepare a report for the coroner.
