Adelaide is the capital and largest city of Southern Australia. It can be the starting point for nearby wine degustation in the Barossa Valley as well as long distance train rides to Melbourne-Sydney or Darwin (the Ghan).
Alice Springs is located in the geographical heart of Australia, on the Ghan train route. The area has been inhabited for thousands of years by the original population of Australia. You can rent a 4WD or take a helicopter ride to Uluru.
Uluru (Ayers Rock) is a huge monolyte. Only 10% is above ground, the rest is below. The Rock is sacred for the original inhabitants of Australia - the Aboriginals. Since October 2019 it is no longer possible to climb to the top.
Barossa Valley, 1 hour North of Adelaide, is one of the main wine areas of Australia and probably in the world. It is fun to try some samples at the different vineyards without getting drunk. If lucky you can even go on a balloon ride and enjoy the views.
Broome is a coastal, pearling and tourist town in the Kimberley region of Western Australia between Perth and Darwin.
Coober Pedy is a "mining" town, sometimes called "the opal capital of the world". You may stay a night at a hotel here under ground (where it is cooler).
Darwin is the place to be if you like nature and warmth. "Kakadu National Park" and crocodiles just around the corner. The Ghan starts here... This is the smallest provincial capital of Australia and quite close to Indonesia.
Exmouth is located between Perth and Darwin on Australia's West Coast. The city has an airport that can be used to reach the famous Ningaloo reef.
Ningaloo is one of the most pristine reefs in the world known for its magnificent underwater wildlife that includes not only corals, but also whale sharks and manta rays.
