You do know that Kangaroos (some species) are vermin and damage crops.

Hmm wonder what impact the whale population have on the annual plankton harvest...

Australians do not eat Bilby's - a cuter smaller version of a Kangaroo (kind of - we have weird creatures here) - it is a protected species so we are not allowed to. They also don't eat the Koala - also protected. Seeing a theme?

Interestingly some NZers were suggesting the commercial farming of the Kiwi as it's numbers were dwindling and by farming it you could create a sustainable population...
