Oh Bob, you forgot a few things. They don't just live around creeks and dark gulleys, the Bunyip River is infested with them. So is Parliament House only there they're disguised as the Liberal Party of Australia. The most dangerous place of all is Bunyip, Victoria. They're highly territorial and constantly hungry so a word of warning, stay clear of the aforementioned places and beware the Bunyip, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun the frumious Bandersnatch!

Yup, Oztralia is a dangerous place and not all dinkum is fair. I don't know where Bill got the idea that mutant Kiwi with a bottle of beer in its hand was a Bunyip, Kiwis are strange birds that do odd things with sheep. THIS is a Bunyip.
