i'de sure that the NSW goverment would have minimum standards for animal exhibits, care etc, but that would be the extent of their association with mogo zoo. unlike taronga and western plains, mogo zoo is privately owned by the padey's, a couple who have built it up from scratch in the last decade or so (and i think they deserve a big pat on the back, because they have obviously been VERY busy).
Western Plains Zoo in dubbo on the otherhand, was founded by the govenment-funded zoo board of NSW - the zoo even acquired unused military land in dubbo to build the zoo to house surplus taronga hoofstock (werribee and monarto had similar starts to life).
i don't think theres much chance of mogo becoming a government funded zoo, wouldn't the padey's have to sell it to the government first? as if they would do that, they already have the trust and support of all the statutory zoos as is!
monarto and adelaide are also one and the same (zoos south australia), and it appears the trend in australia is for the states to have one city zoo and one open-range zoo. of course perth zoo has no sister open-range facility (though its on the planning table) and queensland, NT and ACT don't have and public zoos at all!
