Overall, the best times to visit Australia are during spring (September to November) and autumn (March to May).
Due to the country’s vast size, the ideal period varies by region. It is best to visit southern cities such as Sydney, Melbourne, and Adelaide in spring or autumn for mild temperatures. Northern areas, including Cairns, the Great Barrier Reef, and the Whitsunday Islands, are ideal from May to October during the dry season. To explore the Outback and the famous Uluru, April to September offers the most comfortable desert temperatures. It’s best to visit the West Coast, around Perth, and Tasmania from October to April, with warm, sunny weather.
