The death toll from Victoria's floods has grown to two, as communities remain on high alert for the swollen Murray River system to inundate homes.
The 65-year-old man was last known to be on a tractor on a property off Blacksmiths Road at Nathalia on Tuesday afternoon, police said.
A search was begun about 10pm when he failed to return home and the unoccupied tractor was found in floodwaters.
