Two people were rescued from the roof of their car after it became stuck on a flooded Grassmere bridge on Sunday night.
Leading Senior Constable Brooke Pollock said the SES were called about 9pm to help rescue a man and a women who were aged in 30s.
"Two people had to be rescued by the SES swift water rescue team off the roof of their vehicle," she said.
"They are safe and well but unfortunately the vehicle will be there for some time yet."
The car is not expected to be removed until the floodwaters subside.
SES unit controller Giorgio Palmeri said they dispatched three crews and the swift water rescue team.
When they arrived they found there was one person sitting on the roof of the car and one inside the vehicle, Mr Palmeri said.
"The river wasn't flowing much so we put our swift water rescue equipment on and got some life jackets for the people and walked them out," he said.
Paramedics checked the man and woman for any potential injuries.
Mr Palmeri said the incident was a reminder to motorists not to drive through floodwaters.
"Even if you're in a four-wheel-drive, it doesn't take much for it to flood and float away," he said.
Mr Palmeri said the SES notified the water police before they attempted the rescue and were given the all-clear to go ahead.
Moyne Shire works supervisor Liam Arnott said police notified the council on Sunday afternoon that the bridge was flooded and they erected warning signs about 5.30pm.
He said it could be three or four days before the water subsides from the bridge which is prone to flooding every couple of years or so.
Grassmere Road is regularly used as a shortcut for motorists.
Heavy rain over the past week has also closed a number of roads across the Corangamite Shire, or have water across them, including: Maddens Bridge Road, Baileys Road, Depot Road in Terang, County Boundary Road, Roycroft's Road, Eight Mile Lane, Barrs Road, Keayang Road and Smythe Street.
