A 65-year-old man has been found dead in floodwaters in northern Victoria, as communities remain on high alert for the swollen Murray River system to inundate homes.
The man was last known to be on a tractor on a property off Blacksmiths Road at Nathalia on Tuesday afternoon, police said.
Emergency services started a search when he failed to return home about 10pm.
A search overnight found the unoccupied tractor in flood waters.
A family member found the man's body in floodwaters on Paynes Road about 8.45am on Wednesday, police say.
The exact circumstances surrounding the death are yet to be determined but at this stage it is not being treated as suspicious.
It comes after a 71-year-old man was found dead in the backyard of his Rochester home on Saturday.
Evacuation warnings are in place for Echuca and the smaller towns of Barmah and Lower Moira, with the Murray likely to start peaking on Wednesday.
There are concerns river levels could exceed the 94.77 metres recorded during the 1993 floods.
Echuca residents have spent the past few days building a makeshift, 2.5-kilometre flood levee from sandbags to protect thousands of homes and businesses.
However, the wall has divided the town in two, leaving properties and people on the wrong side susceptible to being inundated.
Julie and Martin Golledge say they are devastated they and their house is at risk.
"We are stranded, we can't even get out," Mr Golledge told Nine's Today program.
"You work hard all your life, you buy a nice house to retire into then the council say 'You're not worth saving' It's just hard."
Flood warnings are also in place for towns along the Loddon, Campaspe and Goulburn rivers.
Overnight on Tuesday, major flooding happened at Appin South on the Loddon River and at Rochester on the Campaspe River with residents being told to move to higher ground.
Major flooding at Kerang from the Loddon River is expected overnight on Wednesday, with the water forecast to peak around the January 2011 level.
A sandbag levee is expected to keep the majority of the town dry, but it could be cut off for up to seven days.
Floodwaters are starting to recede in the hard-hit towns of Rochester and Shepparton but Premier Daniel Andrews warned the state's flooding risk was far from over.
Up to 400 Australian Defence Force personnel are being deployed across the state to help with sandbagging, rescues and deliveries of supplies to flooded communities.
The state government on Tuesday announced a $5.5 million food relief package to ensure affected families don't go hungry.
Free kindergarten is also available for families in flooded communities, while senior students sitting their VCE exams will also receive additional support.
With the state's river systems already reaching their peaks, the Bureau of Meteorology has warned more rain and thunderstorms are on the way.
There could be between five and 15 millimetres of rain for much of the state on Friday, while the northeast could record up to 50mm.
Residents are being advised to heed the flood warnings and evacuate or move to higher ground if necessary.
They should also stockpile medication and other emergency supplies in case they are cut off and avoid driving through floodwaters.
