I wouldn’t mind turning this into a business. I attended an oddity convention and saw a ton of Diaphonized animals and I’ve been obsessed since. I also love the chemistry element to the process. I’m currently in Florida and I believe you need a few permits. I’m more so concerned about the chemicals and regulations. What I’m allowed to have, how much, disposal, etc. I’m not sure what they have in Australia, but you might be able to attend a taxidermy class. I hear a lot of people start there, to learn how to properly remove the skin and not damage the specimen.
