Well what do you know, wish I had been able to keep her!
The stickers on the doors I actually took the paint off, and they were a mailled fist over a boomerang, denoting school of armour, although painted over I could see why you thought they were frill neck lizards!
The rest fits with what I recall from the chap we bought it from who had purchased her from a chap down the east coast. I'd love to see some photos, even if it would be sad not owning her any more (in fact any photos you have i'd love to see

). Amazing to know the whole story though. It's on about it's 6th or 7th owner now as I know the current owner in victoria who bought it form the young tasmanian chap I sold her to.
