Australia's Bioregions

Australia's Bioregions

Australia's bioregions are diverse ecological areas defined by their unique climate, geology, flora, and fauna. The country is divided into 89 bioregions, ranging from tropical rainforests in the north to arid deserts in the center and temperate forests in the southeast. Each bioregion supports distinct ecosystems and species, many of which are found nowhere else in the world. This diversity reflects Australia's vast size and environmental variation, making it one of the most ecologically rich continents on Earth. Conservation efforts often focus on these bioregions to protect biodiversity and maintain ecological balance. The Earth Climate Centre is committed to undertaking climate assessments relevant to Australia's bioregions as part of its Australian Climate Update. You can read more about that here. You can also see an example of climate mapping for this geography using data from Winter 2025 below. Please note that climate maps are best viewed on a desktop with a sufficiently wide screen, otherwise the display will appear too cramped.
