The sheer size of Australia makes it difficult to see the country in just a few days or a week. If you have limited time, it is a good idea to choose a specific region and explore it fully. If you have three weeks or more, you could fit in one or two regions, like New South Wales or the Gold Coast. Ideally, we recommend spending at least 10 days or a fortnight in Australia. But again, the longer you stay, the better.
