Feed it to the dogs
Kangaroo meat was not prized as a meat-source until recently. Any culled animal was usually used as pet-food or "fed to the dogs".
BUT now the commercial viability of kangaroo meat and products has been recognised, it is available at local supermarkets and meat-suppliers, as well as exported overseas.
Some supermarkets also sell emu, crocodile, wild pig and other game species.
I expect that the trick will be to get consumers to try something other than beef, pork, lamb and chicken.
