The residents of Venus Bay and Tarwin Lower in Victoria's east have had their main access road cut by floodwaters.
Since flooding began on Tuesday, the Inverloch-Venus Bay Road, which connects the small towns to Inverloch, has been closed.
Venus Bay resident and South Gippsland Shire councillor Sarah Gilligan told Melissa Fistric on ABC Gippsland radio that residents were still in a watch and wait situation.
The danger point is when there is a lot of water coming down from the Strezlecki Ranges and coming down the Tarwin River if it's meeting high tide that's when it's going to push over the banks, Ms Gilligan said.
Walkerville Road is the only way into or out of the town.
She said Walkerville Road had some water encroaching across it a couple of days ago, and I'm hoping that it's going to remain open with the renewed rain.
Ms Gilligan said landslips and potholes were forming due to the poor weather.
She said there are a lot of new big craters in the roads. I wouldn't even call them potholes.
The councillor reminded residents not to drive through floodwaters, especially when emergency services were already stretched.
She said that she encourages everyone to rethink their plans, lower their expectations and don't drive if you can't avoid it.
Luke Keily, Tarwin Lower IGA manager, told ABC Breakfast that it had been challenging to get deliveries in with the current road conditions.
A lot of Melbourne distributors are not very interested in coming out here so a lot of them have been dropping off their stuff inverloch and Meeniyan, Mr Keily said.
The manager has been driving to nearby towns to collect supplies for the store.
What was the 20 minute trip to Inverloch is now an hour and just shy of an hour and 10 minutes, he said.
We're getting low of a few things I know milk we're getting low of so I'm hoping to get that tomorrow, but we're still all right, Mr Keily said.
There was more wet weather on the way.
The Bureau of Meteorology meteorologist Phoebe de Wilt said rain would increase throughout the day.
The rain is expected to ease off by tomorrow morning, but there are more cold fronts expected as early as Monday.
She said that with the already saturated catchments that we have, we can expect renewed river rises over the next week.
There will still be scattered showers on Saturday, according to Ms de Wilt.
She said that Monday will be quite windy, and that she is urging people to keep up to date with the warnings and any advice from local emergency services.
