I have tasted crocodile both in Perth and in Darwin.
It is really nice however far too expensive in Perth to buy.
It WAS cheaper in Darwin and there are a few other products made from it -I had a "dip" on a tour I did -you would not have known what it was anyway, and I really liked it.
I believe alpaca/llama meat is very good but having bred llamas, it is one food I could probably not eat.
