The locals were all telling me this is a life size model of the largest crocodile, killed in the early 1900s. I’m not convinced. It looks petty mean though. It doesn’t matter how big your knife is, if you met one of these in the wild you’d have no chance.
When I was going to Burketown to fly the morning glory a few years ago, I asked the guy in the gun and sports shop what the best thing for defence against crocodiles was. He put a pair of Nikes on the counter. I think he’s probably right!
