There is a particular kind of Australian cold that catches people by surprise. It is not the deep, snowbound cold of northern winters, but a damp evening chill after a hot day, or a clear winter morning in Canberra, Hobart or the Blue Mountains when the house feels colder inside than out. A good wool blanket is made for exactly those moments: it warms you quickly, breathes as the night changes, and never feels heavy on the bed.

Why wool regulates temperature in winter and summer
Wool works differently from most bedding fibres because each fibre can absorb moisture without feeling wet, then release it slowly as conditions change. That buffering keeps the air around your body steady. On a cool night, its crimped fibres trap air and hold warmth close to you. On a warm night, the same structure lets excess heat and moisture escape, so you are less likely to wake up overheated and damp. In Australia, where one day can swing from a warm afternoon to a cold night, that adaptability matters more than thickness.
Wool versus synthetic fleece
Synthetic fleece has its place. It is cheap, light and easy to wash, and for a spare bed it can be practical. But its plastic fibres do not breathe in the same way: fleece traps heat until you feel clammy, then cools quickly once you throw it off, and it can hold odours. Wool, by contrast, feels dry even while it manages moisture, resists odours naturally, and lasts for years if looked after. It usually costs more at first, yet a well-made wool blanket can outlast several cheaper fleeces. When you are comparing wool blankets australia with synthetic options, think about how you sleep, not only about the price.
Weights and sizes for Australian beds
Weight is a better guide than thickness. A light wool blanket of around 300 to 400 grams per square metre suits mild nights and layering, while a heavier blanket of 500 grams per square metre or more is better for cold southern winters. Layer it in winter with a doona, and use it alone in summer. For size, allow a generous drape. A single bed suits about 160 by 200 centimetres, a double about 180 by 220, a queen about 220 by 240, and a king about 240 by 260. Measure the mattress and choose the next size up if you are between sizes.
Caring for wool: airing, gentle washing and summer storage
Wool needs less washing than most people expect. Air it often in fresh air, out of direct sun, and it will freshen up on its own. Spot-clean small marks rather than washing the whole blanket. When a wash is needed, use cool water, a gentle wool detergent and a wool or delicate cycle, or hand wash and press the water out without wringing. Dry it flat in the shade, away from heaters. For summer storage, make sure it is completely dry, fold it loosely, and store it in a breathable cotton bag with cedar or lavender to deter moths. Avoid plastic bags, which trap moisture.
Choosing a blanket for different states
Australia is not one climate, so one blanket does not suit every home. In Tasmania, Victoria and the Australian Capital Territory, a heavier wool blanket, often layered with a doona, is a sensible winter investment. In New South Wales and South Australia, a medium-weight blanket is the most versatile choice, warm enough for winter and light enough for the shoulder seasons. In Queensland, the Northern Territory and northern Western Australia, a light wool blanket is ideal: it takes the edge off air-conditioned rooms and cool winter evenings without overheating you in summer.
Wool blankets ask for a little more care than fleece, and they repay it with comfort through every season. Choose the right weight for your state, size it generously, air it often, and a good wool blanket will be the layer you reach for year after year.
