This was one of my husband's old photos from when he was a teenager and he doesn't remember much about the visit. Sorry! He hasn't been back there since.
They lived in a small concrete yard(as in the photo) and it was very basic accomodation. The females at least were exercised or let out into the valley paddocks and were probably allowed to bathe in the lakes, hence their good skin condition.
There was also a bull. He was put down as he became unmanageable. Elephants were a very unsuitable species for a relatively small wildlife park like Cricket to take on...
