Australia spans tropical, subtropical, desert, grassland, temperate, and alpine environments. The city and even the side of a mountain range matter more than the national label.
How do the main regions differ?
Darwin, the Top End of the Northern Territory, Cairns, and far-north Queensland are tropical. They stay warm through the year and organise life around a humid wet season and a drier, more comfortable period.
Brisbane and south-east Queensland are subtropical, with warm humid summers and mild winters. Sydney sits farther south and has a coastal climate with rain possible through the year.
Perth and Adelaide have hot, dry summers and more winter rain. Melbourne and Hobart have stronger seasonal changes, cooler winters, and rapidly changing weather. Canberra's inland elevation brings hotter summer days, cold winter nights, and regular frost.
Alice Springs and much of the interior are dry, with strong day-to-night temperature swings. Australia's alpine areas in New South Wales, Victoria, and Tasmania can receive snow.
When are Australia's seasons?
Australia is in the Southern Hemisphere. Summer runs from December through February, while winter runs from June through August.
The Bureau of Meteorology uses a different everyday frame in northern Australia: the wet season runs from October through April and the dry season from May through September. The change is about rain, humidity, winds, and storms rather than a cold winter.
Bushfire, tropical cyclone, flood, severe storm, and heatwave exposure also varies by place and season. Check the local hazard map and insurance terms for a specific address.
What should you check in a home?
In Darwin or Cairns, look for air conditioning, ceiling fans, shade, airflow, mould history, drainage, and cyclone-related building information.
In Brisbane and Sydney, inspect ventilation, afternoon sun, damp, and flood exposure. In Perth and Adelaide, summer shade and efficient cooling matter.
In Melbourne, Canberra, Hobart, and inland towns, check insulation, draughts, heating type, window quality, and winter condensation. Australian homes can feel colder or hotter indoors than an overseas mover expects.
Common misconceptions
Australia is not permanently hot. Frost affects Canberra and inland southern areas, while snow falls in the south-east high country and Tasmania.
The north does not follow the same four-season rhythm as Melbourne. Its practical divide is wet versus dry.
Summary
Choose an Australian climate by city and neighbourhood, not by country. Compare humidity, overnight heat, winter heating, rainfall season, and local hazards.
Inspect the building for that climate because indoor comfort can differ sharply between two homes in the same city.
