What irks me about the story is that (as to the current lack of conclusive proof) they say:
"There are only two alternative explanations: the monsters' non-existence or the searchers' incompetence. It's possible that the animals simply don't exist, and the "evidence" is either hoaxed or the result of honest mistakes. Or, if these monsters do exist, the searchers apparently aren't good enough at their task and can't find the huge animals despite decades of effort and employing high-tech equipment. "
I don't think this is going to work... but at least it will give the sceptics another branch of disbelief to hang on to.
In my personal opinion, the people who have gone "out there" trying to "prove existence" have not done so for monetary reward. Therefore offering a monetary reward, will, at best, only encourage more people to go "out there" to experience the Yowie/Sasquatch phenomena... whether this is a good thing or not, I do not know.
Also, if I were a representative of the company, and someone offered me conclusive photographic proof of the existence of the Yowie, I could easily argue that it wasn't a Yeti, or Sasquatch... and thereby welch on the deal!
