The national emblem of Australia (Commonwealth Coat of Arms) has two native animals the kangaroo and emu holding a shield featuring the six states.
It's believed that the kangaroo and emu were chose to symbolise a nation moving forward (ever seen a kangaroo hopping or an emu strutting backwards).
But did you know that last year, the government authorised the culling of more than 3.5 million kangaroos, that is 3,500,000 !!
