Time Zones
Australia is the largest country in Oceania and the world's sixth-largest country, with an area of 7,617,930 square kilometers (2,941,300 square miles). Australia is the world's oldest, flattest, and driest populated continent, having the least fertile soils. With deserts in the center, tropical rainforests in the north-east, and mountain ranges in the south-east, it is a megadiverse country with a broad variety of landscapes and temperatures.
Australia is a vast country with a small population and three distinct time zones. I'd say it's a lot for a single country. Eastern Standard Time (EST) for eastern states, Central Standard Time (CST) for the Northern Territory and South Australia, and Western Standard Time (WST) for Western Australia are the three time zones.
It's worth noting that CST is half an hour behind EST, whereas WST is two hours behind EST. So, if you've decided to fly to Western Australia in the morning, you've got two more hours to think about it.
