One of the reasons I chose that link was because that isn’t the one in Sydney: it’s the regional branch out in the middle of rural small-town NSW. In outback NSW, a three-hour drive just means that you’re going to the post office.
Taronga-Sydney moved most of their big animals out to the country a few decades ago. There just isn’t enough room to house them humanely in the city.
Any decent zoo should have an active engagement program with regional schools, including travelling educators.
Besides, rural Australian kids aren’t exactly lacking in experience with wildlife.
