I don't know too much about these, except they were released in AUS.. I know about the Ice (transparent) and Atomic Purple.. What I would really want to know, is if there's more of them..
I have seen some of these as I live in Australia but i have not seen a boxed one for a long time in person the ice one and the purple are going to be the easy ones to find i am unsure if there is any more but i remember a green gameboy color released only here i think it has a kangaroo or Australian flag on it or maybe it was a gameboy pocket not sure

When looking at some pics of the box for it, on the left side of the pic of the GBC, it says, vertically, "Limited Edition Green And Gold Neotones" Will be interesting to see if there's more of them.. Thanks for mentioning the Ozzie.. I knew about it, but did not realize it was a neotone one For your reference, here is the box for it (and the console) (found on the net): http://www.nintendo-collection.com/Mes GB Color/Ma GB Color Australienne OZZIE!! Edition.JPG
Hmmmm intresting it has Michael Klim on the box he is a very famous Australian swimmer so i am guessing this cameout in Australia around the time of the Sydney Olympics ^^
I don't know why you post links and responds to your own links, but.. It don't seem like any of the GBCs on the page says neotones.. It's just a long list of different ones..? Anyways, thank you ^^,
