Animal food is available at $3 a bag at the entrance, although the management gave my daughter a freebie because it was late in the day and the animals might not be hungry any more.
As it turned out, some animals had self-control while others were insatiable. Most of the birds were disinterested in our seed and hay mix, as were the alpacas. Kangaroos had a mouthful or two if Little Miss approached them but were not keen enough to get off the ground and hop to her. However she was almost bowled over in the rush by goats, deer, and what are probably Australia's chubbiest sheep, to get to her brown paper bag of food.
This would be a great place to take foreign visitors to interact with Australian wildlife. For Perth locals, it would be part of a good day trip to Mandurah or Pinjarra but probably not worth a trip on its own.
