@RatioTile I wish! the only non-Australian geckoes I have ever seen are Tokay Geckoes and Madagascan Giant Day Geckoes at the Melbourne Zoo. Both stunning species though.
According to the Exotic Reptiles and Amphibians in Australia thread Four exotic gecko species are kept in Australian Zoos. (copy pasted form the thread).
