Lives will continue to be put at risk if immediate action isn't taken to keep wildlife inside the Tower Hill State Game Reserve and off the roads.
Those are the thoughts of Moyne Shire councillor Jim Doukas after two more confrontations with cars and wandering kangaroos from the state game reserve last week.
In 2016, Cr Doukas called for a cull of kangaroos at Tower Hill, something he has revisited.
"You have to keep the numbers down, if you don't the number of kangaroos outgrow the feed available and they get through the fences and onto the roads," Cr Doukas said.
"It (collisions) just happens too often, culling of the kangaroos must happen or the problem will continue to grow."
Cr Doukas has also called on Parks Victoria to improve its perimeter fencing at Tower Hill.
State government funding of $11.3 million has been allocated to revitalise Tower Hill, with a draft plan released for public comment.
Included in this draft plan is a suggestion to remove the perimeter fencing and find an alternative solution for wildlife protection.
"A new fence needs to be a priority," Cr Doukas said.
"If they have a better solution then they need to fast track that, something needs to happen."
The first of the most recent accidents occurred last Tuesday at 1.20am, when a kangaroo leapt out in front of a car on the Port Fairy side of the Tower Hill State Game Reserve entry on the Princes Highway.
The Port Fairy woman driving the car had been driving slower than normal with concerns about kangaroos fuelling this cautious approach.
While both the woman and her passenger were not injured in the collision, the front end of her car did cop significant damage.
The woman believes the couple may not have been so lucky had she been driving at a higher speed.
The next accident occurred on Friday at 7pm along the Port Fairy-Koroit Road in Crossley with a similar outcome, with damage to the car but no injuries to the single occupant.
The accidents were the latest in a string of collisions between kangaroos wandering from Tower Hill and cars travelling on external roads surrounding the state game reserve.
Better management of Tower Hill is on the top of Sergeant Pat Day's list of measures to reduce the risk posed by wandering animals from the state game reserve.
Sergeant Day said the two collisions with kangaroos and cars last week were the latest in a long line of hits and near misses.
"I'd like to see better management of the park as the first step," Sergeant Day from Koroit police said.
"You can see the large amount of kangaroos in the paddocks around Tower Hill and now in the emu breeding season there are mothers with their chicks out on the road.
"The management of the park and the animals needs to be looked at sooner rather than later."
Sergeant Day said wandering animals from Tower Hill posed a host of problems for drivers.
Last week's accidents happened at two collision hotspots, but are not the only reported locations of cars and animals coming together.
Sergeant Day said the uncertainty faced by motorists provided unique challenges.
"The kangaroos are big animals and very unpredictable, you're not sure what direction they will come from," he said.
"You can see them in the paddocks, and if they get frightened they take off across the road.
"The lady who hit the kangaroo on the highway last week used her local knowledge to slow down which lessened the impact.
"But that just shows how challenging it is, even though she had taken that cautious approach, she couldn't avoid hitting the kangaroo.
"We have a lot of visiting people use the highway who are not aware of the possible danger so we do need to do what we can to keep the animals off the roads."
