Mr Weyrich said with several attempts to have kangaroo numbers reduced coming to nothing so far, there must instead be investment in clean up.
His new appeal comes after witnessing a young female driver collide with an already dead kangaroo in the middle of the highway between Deniliquin and Moama on Wednesday.
Mr Weyrich said it is only sheer luck the woman was not severely injured or killed.
“She was following a semi trailer, and I was behind her,” Mr Weyrich explained.
“Just as we passed Moira Station, the semi veered into the other lane. I initially wondered why, until her little car hit this big roo in the middle of the road.
“Her car lifted onto two wheels, and it’s just lucky she didn’t flip completely.
“I stopped and spoke with her and to take a look, and it seemed like the roo was only recently killed.
“Most days you see at least one or two dead roos on the road, sometimes more.
“If the government won’t help us reduce kangaroo numbers, someone should at least be going out and cleaning up the carcasses every day - before someone is killed.”
Mr Weyrich has been arguing for a kangaroo cull in the region for more than a decade, particularly between Deniliquin and Moama.
When he was a councillor with Murray River Council, and Murray Shire Council before that, Mr Weyrich tried on multiple occasions for the NSW Government to work with the communities on a suitable solution.
A motion along these lines was supported by majority at the Local Government NSW conference in 2017.
All motions passed at these conferences are then referred to the NSW Government to enact, but Mr Weyrich said it was either ignored or shelved.
Mr Weyrich said the result is a “prolific” problem, which is becoming more widespread.
“Each road in and out of Deniliquin has a roo problem, and it’s not just at dawn and dusk. They’re being hit at all times of the day and night.
“The numbers are exploding, but the state government continues to stick their head in the sand.
“Something has to be done.”
