Like the above comments, i think acknowledgment of the Yowie or "Tassie" Tigers would be a huge inconvenience for the Miners, developers and the establishment in general. Much like Indigenous people and endangered species are an inconvenience to the loggers in the Amazon. Its all about the dollars!
I also think a lot of these elite types know all about them. They would have to so they know to ridicule it when bought up.
I find mentioning it and pretending to not know about it gets some interesting answers. I had a judge slip up big time when i mentioned how Id heard that Yowies were seen in the forest near his mansion fringing the mountains. He said " oh they dont come down this far" before stumbling and correcting himself with " preposterous" or something similar to which i agreed of course.
Whats even funnier when you do know the truth and these idiots..sorry i mean the uninformed masses tell us that the Yowie doesnt exist before the usual mocking and ridicule kicks in. Meanwhile they fill there heads with b.s scripted reality shows and fake news, silly trends and music. Gotta fit in and all that! Haha!
The Yowie community doesnt help itself either with the disagreements on the origins and hoaxing etc. No one really has to debunk anything as its all naturally taken care of!
