A Toyota four-wheel-drive was stuck with water rising up to the top of its tyres on Koroit Creek Road, Williamstown North.
Emergency services responded to the incident and safely rescued the pair.
Parts of the state will experience heavy rain and unseasonably cold temperatures.
Yesterday was the coldest November day on record in parts of Victoria.
The system, which has already caused heavy rain and strong winds, is set to move off the south-east coast of the country this afternoon.
But a strong cold front is forecast to set in on Sunday afternoon that will bring more rainfall and possible thunderstorms to Victoria.
The main concern is the Gippsland region, in the state’s east, where there has been flash flooding and strong winds.
The region has recorded 100mm of rain in the last 24 hours.
State Emergency Service (SES) teams have already been busy.
They’ve fielded more than 400 calls for help – mainly for trees down and for building damage.
“We now have a major flood warning out on the Mitchell River in Gippsland and a range of moderate and minor flood warnings coming today in the north east of the state.”
Mr Wiebusch urged anyone camping in affected regions to avoid pitching a tent near rivers and to check routes on the VicTraffic app.
As the low moves off the east coast it will continue to bring heavy rain to Tasmania, Victoria and NSW before easing and clearing off-shore on Saturday night.
Onshore winds ahead of a front will bring showers to southern SA and southeast WA, while a trough will lead to a few storms in the north as well as drawing heat across WA.
‘Don’t drive through floodwaters’
NSW SES has responded to over 770 requests for help so far, Deputy Commissioner Daniel Austin said.
“The busiest areas so far have been around Armidale, Bathurst and also Orange,” he said.
“Crews are largely responding to flood or storm related calls. Over the last few days (we’ve had) some 21 flood rescues.
“We ask people to really stop and check or not the risk is worth it. Don’t drive through floodwaters.”
Record-breaking rain falls on outback
States were hit with some of their highest rainfall totals in years, sparking flash flooding and rising rivers.
Parts of outback Queensland saw falls of over 100mm, with the highest being 157mm at Red Hill.
But the deluge wasn’t limited to the eastern states with a Bureau of Meteorology (BoM) weekly rainfall total map showing much of the country got a soaking.
Most notably, Alice Springs in the Northern Territory.
In the five days to 9am Thursday, Alice Springs Airport received 153.4mm of rain, which is around five months’ worth of rain for this time of year.
Weatherzone reports that this included 100.2mm in 24 hours – their heaviest daily rain in 21 years at Alice Springs.
