Australia is not small
Venturing on the uncovered trail, no! Roadtrip, better not! Don't get your mind boggled! Australia is simply a big country with so much of empty space in between. Remember, it is also a continent, so don't go prepared to cover the entire country in a week or two. You will just fall flat on your approach. Firstly, the gaps between major cities are larger than those in the US. Secondly, there are few towns in between these gaps. So, unless you want to spend travelling through the wild, don't plan anything that might involve roadtrip (unless you are going along the east coast, which is where most of Australia’s population resides) or untravelled roads.
Tip Choose two or three places you are really eager to visit and cover them before planning to go anywhere else.
Mixed up season
Because Australia is all the way on the other side, there is a misconception that it's seasons are totally opposite when compared to the northern hemisphere. South Australia does face that, but not North Australia. Visiting Sydney during November to April is alright, but don't expect to go to the Great Barrier Reef in that time which will be experiencing downpours.
Loads of natural areas
Wherever there is greenery, the Australians will call it a National Park. It might sound a bit too ambitious, but it looks like Australians cherish their greenery as every one of them are simply stunning.
Australia can make every spot into something interesting and educational. Wherever you go you will encounter a plethora of boards explaining the variety of trees, the fauna that survive in the area, details about the ecosystem and the list goes on.
Australians just love to include large slices of beetroots in sandwiches and Burgers. It might not be a problem if you too love beetroot, but for those who have a beetroot allergy or can't stand the vegetable, make it a point to always say no beetroot while ordering even if it doesn't make an appearance in the menu.
