The flight to Australia is far and long but if you want to experience a bit of the nature of Down Under, the Gan Guru is a great zoo.
You walk right between the kangaroos who do not seem to be bothered by you starring at them. They even! have two koalas and many more of Australia's natives. You get to feet the loris with apples on a stick, they are so crazy about the fruits that they sit right on your shoulder.
