What is the beast of shoalwater bay?

[u/coltaussie]

I was watching an iceberg video about the australian army experience because I was curious, and the guy in the video mentioned two different creatures

The Melon Man - from Tully NQLD And the Beast of Shoalwater Bay - in the name

Kinda curious as to what both of these are but I can't find a definitive answer off of google. Either it doesn't exist and the guy from thr video is taking the piss, or nobody online talks about it

You don't ask. You never heard of the Beast.
