September is the first month of spring in most of Australia and still the dry season in the tropical north. Temperatures increase throughout the country but are only slightly higher than in August, and rainfall is still low in the north. Conditions are good for traveling to the various climatic zones around the vast country.
March in Australia is the first month of autumn, and while conditions vary enormously throughout this large country, temperatures begin to cool everywhere. In the southern cities, this is an ideal time to go sightseeing, and beaches still have excellent conditions for swimming. If Easter falls in March, expect plenty of fellow travelers, international and domestic alike.
