well the good news is that since i believe in inevitable that asian elephants will end up at werribee, i also see it as very likely they build an asian themed zone to showcase them.
since werribee is an open range zoo - if they build an asian themed zone the temptation is going to be very much to house the asian rhino species.
by the time they get around to this - in the next 5 - 10 years, WPZ will hopefully have a couple of young animals bred from their pair that need rehoming. hopefully we'll get one, and import a mate.
