What do you need to know about Australia? Yes you need to go here and see everything for yourself! A traveler should definitely come to Australia for a couple of months and fly between the major cities of Sydney, Melbourne, Brisbane, Adelaide, Perth, Cairns, etc. The atmosphere and nature of Europe and Australia contrast greatly, despite the similarities in development and civilization. There is also a huge contrast with Asia, despite the similarities in nature! Australia is civilization and wealth without the pompousness and pathos of luxury, with luxurious nature).
