Australia is the 6th largest country in the world, so knowing when to visit depends entirely on what you’re looking to do, and where it is you’re going. The seasons here are the exact opposite to the northern hemisphere, which means when Europe is basking in the summer sunshine, Australia is battling through winter.
Typically, the northern regions will still be fairly hot during the winter, with little rainfall, while the simmer it’s victim to oppressive heat with serious downpours. Contrastingly, the southern areas have cooler summers, and almost chilly winters in comparison.
If you’re heading to the south you want to go during January or February for great beach weather, and spot the baby kangaroos learning to hop around.
In terms of festivals and events, there is plenty going on throughout the year. March sees the Melbourne Food and Wine Festival, while the Darwin Festival takes place in August and features outdoor concerts, dance music, theatrical performances, comedy and cabaret, workshops, films, and visual arts.
