Australia is a continent of climatic extremes. Whether you are skiing the slopes of New South Wales in July or diving the Great Barrier Reef in January, the Australian seasons offer a diverse and unique experience unlike anywhere else on Earth.

Perhaps the most sophisticated understanding of Australian seasons comes from the continent’s First Nations peoples. For over 60,000 years, Aboriginal and Torres Strait Islander communities have observed six, sometimes even seven, distinct seasons, tied not to arbitrary dates but to observable ecological cues. Take the Gariwerd calendar of western Victoria, which includes seasons like Petyan (April-May), when the red flowers of the running postman signal the arrival of eels, and Chunnup (November-December), when the call of the koel cuckoo announces the heat before the rain. Similarly, the D’harawal calendar of coastal Sydney describes seasons based on which flowers bloom, which fish are running, and which winds are blowing. These systems are not merely poetic; they are practical tools for survival, dictating when to burn, when to hunt, and when to gather.

When we think of seasons, the traditional four—spring, summer, autumn, and winter—often come to mind, neatly packaged into three-month blocks. This model, rooted in the temperate climate of Europe, works well for places like London or New York. However, to apply this rigid framework to Australia is to miss the country’s true climatic and cultural identity. The Australian experience of seasons is not a single story but a collection of narratives defined by extreme geography, Indigenous wisdom, and a distinctive reversal of the northern calendar.
