Australia is huge
Many people underestimate Australia's true size. You may believe that you can just jump on a fast flight to fly from one side of the country to the other, but this is not the case. In reality, traveling from Brisbane to Perth would easily take more than 5 hours. If you tried to drive, you'd be on the road for more than three days. This isn't ideal, but fortunately, there is so much to do in every location. You might, for example, go see some modern Australian art or perhaps try your hand at surfing.
Australia is enormous. You would assume you can take a short trip from one side of the nation to the other. However, because each state is so large, there is enough to do. There is never a dull day, whether you visit two or more states and territories or stick to just one. Don't feel obligated to see every aspect of this magnificent nation in a single visit; you can always return another year. Maybe it is one of the things about Australia you should know before traveling.
