cairns is not currently an ARAZPA member zoo.
well if they do go to seaworld (that australia's seaworld) which is an ARAZPA member, hopefully that will open up a doorway to distribute genetics between the two lineages. however, we're told the new owner of CWSR does want to join the regional association and so i have little doubt that when that happens, they will follow recommendations that will see vital pygmy and common hippo transfers between the zoos.
1. I am surprised. I checked the ARAZPA site before I wrote my queries and Cairns was actually on that very list. I looked again just now and the Cairns site is the Cairns Tropical Zoo. So forgive me, for being wrong here!
2. CWSR joining ARAZPA would be the way to go! I find the suggestion to move pygmy and common hippos to Sea World a little bit outlandish though. Do the CWSR hippos have an inate love of seawater or what ..
