You can get a licence to shoot kangaroos - the culling has to occur and is regulated. The breed much better now since white man arrived here.
I'm not sure what is done with the meat - I think it may end up as pet food. So those shooting roos are doing it for a business and would not be likely to be using archery equipment, but I don't think they would necessarily precluded from doing so. Rifles are just that much better at culling.
