The state government has announced new funding for both Kentish and Latrobe council to get flood mitigation works underway.
Acting Premier Jeremy Rockliff said the government would provide $3.4 million towards the Railton project and $3.66 million for Latrobe, on top of a previous contribution of $1 million.
"A lot of work has been done on the designs and details (of the projects)... and clearly it is a very expensive exercise when you're talking about such a high levee," Mr Rockliff said.
Kentish council estimates the Railton project will cost about $10 million. For Latrobe council, that figure sits at more than $14 million.
The federal government has previously promised $4.67 million for Latrobe, with the council putting up a similar amount to create a three-way split.
Acting mayor Graeme Brown said this new state government funding would bring the project "to fruition".
"To wake up in the morning and look out and see what was out there was just unbelievable (in 2016), Mr Brown said. "You just couldn't fathom the amount of water."
"There's still a lot of feeling in the community about the floods... and there's a lot of wondering of what's going on to protect us.
"We have a design... and we've come up with one we think will suit the community and work. With the help of the state and the federal government... now we're going to be able to do it."
Kentish Council mayor Tim Wilson agreed.
"In Railton, 2011 was bad but 2016 was worse," he said.
"I remember we went down to the township and the road just peeled away like butter up the main street.
"I say thank you, and I'm very thankful, to the state government. We got stuck. We realised we needed about $10 million, and we're only a small council.
