What would I do? Probably go insane. Australia is the most restrictive country in the world in which to establish and operate a zoo. The amount of nit-picking regulation and restriction in this supposedly free country is unbelievable and wouldn't be tolerated in somewhere like the U.S.
On the other hand, if you asked me what I believe existing zoo administrations in Aust. should do, I would say attempt to agree on which animal species to keep co-operatively (which they do) and perservere with them (which they don't!)
If zoos adopt a species for conservation purposes (for example the red panda) then they should go all out to hold, say, 6 or 8 pairs each; not just one or two. The same goes for Sumatran tigers, snow leopards etc. If they winge about having to do so, they are more interested in Showbiz than conservation. The necessary enclosures should be simpler and more economical to construct. I would be happy with, essentially, a row of something like tennis courts with mesh roofs. The animals don't need these lavish, multi-million dollar immersion exhibits.
