THE Greens have vowed to oppose a Victorian Government push to assess the regulation of a kangaroo meat industry.

Victorian Greens leader Greg Barber said a kangaroo meat industry would result in the licensing of the "creation of thousands of more orphans''.

The issue has been raised in state parliament again today, by member for Western Victoria David O'Brien.

Mr O'Brien said the commercial harvesting of wild kangaroos was not permitted in Victoria, although it is permitted in South Australia, Western Australia, NSW and Queensland.

He asked for the Agriculture Minister Peter Walsh to "turn his continued attention'' to the issue.

He said a kangaroo processing industry was a fantastic environmental solution which also allows people to eat healthy, lean kangaroo meat while protecting, to some extent, the environment from the scourge of too many kangaroos.

But according to Victorian Greens Leader Greg Barber, the Greens will oppose any renewed government push to "kill kangaroos''.

Mr Barber claimed Mr O'Brien's ideas were "a thought bubble that just wouldn't work in practice''.

"It's cruel, it's wasteful, and it wouldn't pass the food safety rules other farmers have to comply with.

"Killing kangaroos by chasing them around in the bush and shooting them is cruel.

"We don't allow that kind of cruelty in a livestock farming operation.

"If we see a wounded joey on the side of the road, we take it to a state government supported wildlife shelter.

"Now he's (Mr O'Brien) calling on the state government to licence the creation of thousands of more orphans.

"Nobody supervises the thousands of permits to kill tens of thousands of kangaroos that are given out already. There's no oversight. Put a a profit motive in there and things will get even worse.''
