Nice place with several things together in one place: beach river waterfall tracks park 

Reptile park with crocodile farm. Here is some laboratory to make antidote for snakes venom. Also the great man here gives interesting talks and shows about animals and especially reptiles.

Great garden located in mountains with plants around the world. Entry is free :)

Small city with a lot of old beautiful buildings. It the past it was very wealthy, the main industry was the wool. Now sheep is symbol of this city. The city still producing the finest wool. 

Beautiful caves. Very beautiful caves. Amazing caves!

Sydney Opera House. The interesting thing about the building is that it was very expensive to build it, it costs 3 times more that expected. It wouldn't build at all if the price were known beforehand.

Sydney Aquarium - the most interesting place here is a aquarium tunnel with sharks, see on the photos.

Very beautiful old mountains. The name is "blue" because of the specific blue fog. This fog is caused by large eucalyptus forest in the mountains.
