What is the top travel destination for australians?

Answer 1

I'd say the capitals of all states (Canberra in Australian Capital Territory - also the Australian Capital, Perth in Western Australia, Adelaide in South Australia, Brisbane and the Gold Coast in Queensland, Sydney in New South Wales, Melbourne in Victoria, Hobart in Tasmania, and Darwin in Northern Territory), and iconic landmarks, such as Wave Rock in Hyden, Western Australia; Harbour Bridge, Royal Botanical Gardens, Luna Park, and the Opera House, all in Sydney; Great Barrier Reef, off the coast of Queensland; Ayers Rock/Uluru in Alice Springs, Northern Territory (smack-bang in the middle of the country, north of the border of South Australia), and others.

There are many travel books dedicated to Australia, plus you have the entire world at your fingertips with the internet, so there's plenty of ways to research more.
