What is more unbelievable: a ghost, a flying saucer, or a yowie? Obviously the last. We know very little about the intermediate state of the soul, we know even less about life in outer space, but we know that a big, hairy ape stomping around marsupial land - and quite undetected by science - is impossible. Bats flew here, and seals swim to our shores. But apart from that, no regular (eutherian) mammal larger than a rat has even reached Australia without human assistance. So you should not be surprised that, when I first heard about yowies, I was sceptical. My scepticism was not lessened by the fact that the main proponent of the legend (not mentioning any names!) was a well known crank. I therefore wrote an opinion for the journal, Cryptozoology debunking the early reports. When it came to my book, Bunyips and Bigfoots, I started the chapter on yowies as an unbeliever, and ended as a believer. As far as scepticism goes, I have been there and done that. Then, after the book was published, new reports started coming in. And since they have not yet been published, or published only in summary, I think it is time to put them on the net.
