The one with the cities? If so, Melbourne, a cultural and sporting city near the Great Ocean Road, will seduce you, just like the chic Sydney, with its opera and its prized beaches. Canberra, the green capital with modern architecture, is worth the detour, not forgetting Perth, a prosperous and relaxed city, isolated in the West.
The Australia of open spaces? Red earth, bush and unusual geological formations? Aim for the central region, with the symbolic and must-see site of Uluru. Kings Canyon, Devils Marbles, Wave Rock, Bungle Bungle or Flinder Ranges will, no doubt, also figure on your list.
The Australia full of adventure and unique encounters? Head to the north, to the heart of the Aboriginal tribes; rock paintings and crocodiles are waiting for you at Kakadu National Park. Cross the Kimberley savannah in a 4x4, stand awestruck in front of the horizontal waterfalls, not forgetting the sunset astride a camel on Cable Beach in Broome.
The Australia of surfing and nautical activities in idyllic locations? Go kayaking on the Whitsunday Islands, dive in the Great Barrier Reef or Ningaloo Reef, its lesser-known equivalent to the west, with sharks and whales. Greet the dolphins at Monkey Mia. Are you a surfer? East, West, South coasts: the spots are bustling, whether it's the waves of Byron Bay, Margaret River or Bell's Beach...
The Australia off the beaten track? Choose Esperance, the pink lake and the beaches of Cape Le Grand. And Tasmania? This forgotten little part of New Zealand will bowl you over with its exceptional fauna and flora.
Now it's up to you to create your unique trip!
