The best month to visit Australia depends on where you plan to visit. Northern Queensland, the Northern Territory, and the northern parts of Western Australia - are driest between April and September; while further south in Brisbane, Sydney, Adelaide, Melbourne and Perth – it’s hottest over summer, December to February. If you’re not keen on high temperatures, but still like sunny weather, try the autumn months of March to May, where you’ll find lots of events both in the cities and regional areas.
