peccaries cannot be imported to Australia. And "rejuvenating bloodlines" isn't an apt description when you are talking about a single remaining specimen (e.g. the flamingo or curassow) or post-reproductive individuals (e.g. the rheas).
@zoomaniac - check the stickied lists at the top of the Australia forum for the mammals and birds still in the country and the populations' general origins.
Saw that list but wasn't sure how relevant/up to date it is.
If I read and translated animal_expert1's first post correctly, then he asked for species no matter if they can be imported by law or not and no matter how expensive it would be...
@Zoofan15: While following the mainstream taste with animals I have to follow here the mainstream taste in icecream flavours as well, haven't I?
