I have a friend in Sweden who is a breeder. I know he works with morelia, lots of Aussie species. I don't believe he keeps retics or burns, but whether that's just his preference or not I'm not sure.
If you'd like I can copy/paste your questions and contact him? He's very eager to help whenever I have questions for him. I'm sure he'd be happy to answer your questions.
Let me know, I'll hit him up if you'd like.
