Nice video but I was unaware of the feral chameleon and meerkat problem in the Grampians. They must've left the elephants, lions, gorillas and pygmy hippos on the cutting room floor. Melbourne Zoo methinks.
They might be at the Halls Gap Zoo? I'm pretty sure they have meerkats and chameleons in there along the cheetahs and other exotics. The zoo sells little paper bags of feed to customers to feed the animals and you can see some of that around the 2 minute mark.
