Very true statement. For many species Europe and America are the main centres of zoo production. As a result, most traffic is 'one way' to Australia/NZ etc and not back again. There are a few exceptions, such as the Melbourne-bred Gorilla 'Mzuri' who went to Jersey UK.
you see a platypus at every wildlife park/zoo you visit? You must be very particular about which ones you visit!
With the exception of Sea World, every zoo or native fauna park you visit has at least 1 platypus (I might be wrong tho )
I suggest you visit more zoos and wildlife parks before making statements of such a sweeping nature, because you are quite wrong
