Doona & Quilt Guide Australia: Everything You Need to Know

A doona is the Australian word for a duvet or quilt — the soft, insulated bed covering that keeps you warm at night. Choosing the right doona means understanding tog ratings, fill types, and Australian sizing, all of which can feel overwhelming at first. This guide cuts through the jargon and helps you pick a doona that suits your climate, your sleep style, and your budget.

Key Takeaways

• A doona is the Australian term for a duvet or quilt — same product, different name.
• Summer: 2–4.5 tog. Mid-season: 7–10 tog. Winter: 10.5–13.5 tog.
• Down is the warmest and lightest; wool regulates temperature year-round; microfibre is the best budget option.
• Buy one size up from your mattress — a queen doona for a double bed prevents the "blanket tug" between partners.

This guide covers everything you need to know — what a doona actually is, how to compare fillings, tog ratings, sizing, seasonal choices, covers, care, and a step-by-step buying checklist.

What Is a Doona? (Doona vs Quilt vs Duvet vs Comforter)

A doona is the Australian term for a soft, insulated bed covering — the same product known as a "duvet" in the UK and Europe, a "comforter" in North America, or simply a "quilt" in casual Australian usage. All four names refer to the same basic concept: a fabric shell filled with insulating material (down, wool, polyester, or similar) that keeps you warm in bed.

Why do Australians say "doona." The word entered Australian English in the 1970s through Kimptons, a Melbourne-based bedding company that branded its down-filled quilts as "doonas." The name itself traces back to the Danish dyne (a down-filled quilt), reflecting the Scandinavian origin of the product concept. The Kimptons brand was so successful that "doona" became the generic Australian term — similar to "Band-Aid" for adhesive bandages or "Esky" for portable coolers. 

Key terminology differences:

• Doona/quilt — the Australian terms, used interchangeably
• Duvet — the UK and European term (technically a two-piece system with a removable cover)
• Comforter — the US term (typically a single quilted piece with cover and fill sewn together)

In practice, in Australia, "doona" usually refers to the duvet-style insert that you slip into a separate doona cover. The cover is washed weekly; the insert is cleaned occasionally.

Doona Fillings Compared

The fill inside your doona determines how warm it feels, how long it lasts, and how much you pay. Here's how the main options stack up:

Down (duck and goose). The premium choice. Down is the soft, fluffy under-layer of feathers from ducks or geese. It has the best warmth-to-weight ratio of any natural fill — meaning a high-warmth doona stays light. Goose down is loftier, warmer, and more durable than duck down; both are far warmer than synthetic options for the same weight.

Feather and down blends. A mix of soft down clusters and quill feathers. Cheaper than pure down, slightly heavier, and still excellent for warmth. The most popular natural-fill option for Australian buyers on a moderate budget.

Polyester microfibre. Synthetic fill designed to mimic the feel of down. Hypoallergenic, machine-washable, and dramatically cheaper than down. Available in all tog ratings. The best budget choice for most Australian sleepers. Koala offers this style with the Balmy Night Duvet — Clusterloft® fibre that mimics down's softness while staying breathable.

Wool. A natural temperature regulator that keeps you warm in winter and cool in summer. Wool wicks moisture (so you sleep drier), is naturally hypoallergenic, and resists dust mites. Wool doonas are particularly well-suited to Australian climates with cool winters and warm summers. The Koala Duvet 2nd Gen features wool fill with a modular snap-system for adjustable warmth across seasons. 

Cotton. Lightweight, breathable, and easy to wash. Cotton fill is often used in summer-weight doonas because it's cool to sleep under. Less insulating than down or wool, so not a winter option. For a year-round option, the Koala All Seasons Duvet uses a 55% TENCEL™ Lyocell + 45% cotton blend designed for breathable comfort across summer and winter.

Bamboo. Naturally cooling, moisture-wicking, and eco-friendly. A growing favourite in Australia for hot sleepers and humid climates. Often blended with cotton or microfibre for structure.

Silk. Luxury fill that's lightweight, naturally hypoallergenic, and temperature-regulating. Excellent for sensitive sleepers, but expensive and harder to wash.

Tog Ratings Explained

A tog rating measures the thermal insulation of a doona — the higher the tog, the warmer the doona. Tog ratings are the standard system used across Australia, the UK, and Europe for grading bedding warmth.

Australian seasonal tog guide. Australian bedding guides recommend the following ranges for most local climate zones: 

All-season doona sets. Some doonas come as a two-piece system: a 4.5 tog summer doona and a 7 tog mid-season doona that can be clipped together to create a 13.5 tog winter doona. This is the most flexible option for most Australian climates because you only need one purchase to cover all seasons.

How Australian climate zones affect choice:

• Tropical (Darwin, Cairns, Townsville): 2.5–4.5 tog year-round; air-conditioning is the main warmth control
• Subtropical (Brisbane, Gold Coast, northern NSW coast): 2.5–4.5 tog summer, 7–10 tog winter
• Temperate (Sydney, Melbourne, Adelaide, Perth, Canberra): 4.5 tog summer, 10.5–13.5 tog winter
• Cool temperate / alpine (Hobart, Snowy Mountains, Tasmanian highlands): 4.5 tog summer, 13.5+ tog winter

Tog vs GSM. Some Australian retailers list "GSM" (grams per square metre) instead of tog. GSM measures fill weight, not warmth. The two correlate roughly:

• 150–250 GSM ≈ 2.5–4.5 tog (summer)
• 250–400 GSM ≈ 7–10.5 tog (mid-season)
• 400+ GSM ≈ 12+ tog (winter)

But tog is more reliable because warmth depends on fill type, not just weight. A 200 GSM down doona is much warmer than a 200 GSM microfibre doona at the same weight.

Doona Sizes in Australia

Australian doonas follow standard sizing tied to mattress dimensions. The general rule: buy a doona one size larger than your mattress so it overhangs comfortably.

Standard Australian doona dimensions. The most common doona sizes in Australia: 

Why size up. Many Australians make the mistake of buying a doona to match their mattress size exactly. The result: when one partner rolls over, the other gets pulled out from under the doona. Buying one size up gives you 30–40 cm of overhang on each side — enough to keep both sleepers covered through the night.

Overhang recommendations:

• Solo sleeper: match doona size to mattress
• Couples: size up by one (queen mattress → king doona)
• Couples who fight for blankets: size up by two (queen mattress → super king doona)

Best Doona for Summer

A summer doona keeps you covered without overheating. The best summer doonas are lightweight, breathable, and low-tog.

Lightweight fills. Cotton, bamboo, and microfibre with low fill weight are the top choices. Avoid heavy down or wool fills in summer — they're designed to retain heat.

Low tog ratings (2–4.5). A 2.5–4.5 tog doona is light enough to sleep under without overheating, while still providing some warmth for cooler summer nights or air-conditioned bedrooms.

Breathability and moisture management. Look for natural fills (cotton, bamboo) or moisture-wicking microfibre. Synthetic fills that don't breathe (cheap polyester) trap sweat against your body — uncomfortable in humid Australian summers.

Australian summer considerations. Many Australians sleep with air conditioning during summer, which changes the maths. Air-conditioned bedrooms can stay at 18–22°C overnight, meaning a slightly warmer (4.5–7 tog) doona may still be comfortable.

When to swap. Most Australians switch to a summer doona around late October and back to winter weight around April. In tropical Queensland or Darwin, a single summer doona may serve year-round.

Best Doona for Winter

A winter doona keeps you warm without weighing you down. The best winter doonas combine high loft with good breathability.

High-loft fills. Goose down has the best warmth-to-weight ratio — meaning a winter-warm down doona is much lighter than an equivalent microfibre or wool option. Wool is heavier but excellent for those who prefer the natural feel and temperature regulation.

High tog ratings (10.5–13.5). A 13.5 tog doona is the winter standard for Melbourne, Hobart, and inland New South Wales. Sydney, Brisbane, and Perth winters often only need 10.5 tog; Tasmania may need an extra blanket layered with the doona.

Layering vs single heavy doona. Two approaches work for winter:

• Single heavy doona (13.5 tog): simple, warm, but harder to adjust mid-night
• Layering (4.5 + 7 tog clipped together, or doona + extra blanket): more flexible — you can remove a layer if you overheat

The layering approach is particularly useful for couples with different temperature preferences.

Cold climate vs mild winter. A Melbourne winter (cold, often damp) needs a 13.5 tog doona; a Perth winter (mild, dry) is fine with 10.5 tog. Adjust based on your bedroom heating — heavily heated bedrooms can stay comfortable with lighter doonas.

Heating and doona weight balance. If you run heating overnight, you'll need a lighter doona than someone who turns the heating off. Aim for a sleeping bedroom temperature of 16–20°C and choose tog accordingly.

How to Choose a Doona Cover

The doona cover is the fabric shell that surrounds your doona insert. It's what you actually wash regularly, and it has a big impact on how the doona feels against your skin.

Material options. The main fabric choices for Australian doona covers:

• Cotton: breathable, easy to wash, affordable. The default for most bedrooms.
• Linen: beautifully textured, breathable, and durable. Wrinkles more — part of its charm for some, frustrating for others.
• Bamboo: silky, naturally moisture-wicking, ideal for hot sleepers
• Microfibre: the cheapest option; less breathable, but easy to clean

For a deeper look at sheet and cover fabrics, see our bamboo vs cotton sheets comparison.

Thread count. For pure cotton doona covers, 200–400 thread count delivers the best balance of softness and breathability. Higher thread counts (600+) often involve multi-ply yarns and are mostly marketing.

Closure types.

• Buttons: classic, secure, look good on premium covers

• Zipper: fastest to use, best for daily-changeable covers

• Ties: traditional, less secure, can come undone overnight

Colour and styling. Neutral covers (white, oatmeal, sage, charcoal) suit any bedroom and last longest visually. Patterned or seasonal covers are fun but date faster.

Easy-wash requirements. Cover the doona insert with something you can wash weekly. Linen and cotton are best. Avoid silk or velvet covers — they're high-maintenance for daily bedding.

How cover material affects sleep temperature. Bamboo and cotton breathe well and stay cool against the skin. Microfibre and synthetic covers can trap heat — fine in winter, uncomfortable in summer.

Caring for Your Doona

Proper care extends doona lifespan dramatically. Here's how to look after each type.

Washing instructions by fill type. Care varies by fill — always check your doona's care label first: 

• Down / feather: dry-clean preferred; if washing, use a commercial-size washer with cold water and gentle cycle, then tumble-dry low with tennis balls to redistribute fill
• Microfibre: machine wash in a large-capacity washer, cold or warm, gentle cycle, tumble-dry low
• Wool: spot-clean only, or specialist wool wash. Never machine-dry — wool felts when heated.
• Cotton: machine wash, warm water, regular detergent, tumble-dry low
• Bamboo: machine wash gentle cycle, cold water, line-dry preferred

How often to wash. Wash the doona insert every 3–6 months at minimum. The cover should be washed every 1–2 weeks (same as your sheets).

Drying methods.

• Line dry: safest for most fills, particularly natural ones
• Tumble dry: efficient, but use low heat for foam and synthetic fills
• Professional cleaning: worth it for premium down or silk doonas

Storage between seasons. When swapping summer and winter doonas, store the unused one in a breathable cotton bag — never plastic. Plastic traps moisture and causes mould or musty smells.

Doona protectors. A removable doona protector (similar to a mattress protector) goes between the doona and the cover, blocking sweat, oils, and stains from reaching the fill. Hugely extends doona lifespan, especially for expensive down doonas.

When to replace your doona. Quality doonas last 5–10 years depending on fill:

• Microfibre: 3–5 years (fill compresses faster)
• Down / wool / silk: 8–15 years with proper care
• Replace when: fill clumps unevenly, cover stains can't be removed, or warmth noticeably reduces

Doona Buying Checklist

Use this step-by-step approach to find the right doona without overthinking:

Step 1: Determine your climate zone and season needs. Australian climate zones range dramatically. Tropical north → light doona only. Temperate south → all-season set or two separate doonas. Alpine areas → premium winter doona plus a light summer option.

Step 2: Choose fill type based on budget and preferences. Down for premium warmth and lightness. Wool for natural temperature regulation. Microfibre for budget and easy care. Bamboo for hot sleepers.

Step 3: Match tog rating to your bedroom temperature. Cool bedroom (under 16°C overnight) → higher tog. Warm bedroom (over 22°C) → lower tog. Adjust for heating and air conditioning.

Step 4: Select correct size (with overhang). Solo: match mattress size. Couples: one size up. Frequent blanket-fighters: two sizes up.

Step 5: Check washability and care requirements. Does the doona fit in your washing machine, or do you need a laundromat? Down and wool may need dry-cleaning — factor that into the long-term cost.

Step 6: Pair with a quality doona cover. Cotton or bamboo for everyday use. Match thread count and care requirements to your laundry routine.
