The cheapest way to stay warm on a cold Melbourne or Canberra night isn't cranking the ducted heating for the whole house. It's heating the one square metre of couch you're actually sitting on. A heated throw pulls about as much power as a couple of LED globes, so you can run one all evening for a few cents and leave the thermostat where it is.
I've been through a stack of these over the years. Some are genuinely warm and last for seasons, others pill after two washes or run the cord out the wrong side and drive you spare. Below are the types worth buying on Amazon AU this winter, what each is good for, and where I'd actually spend the money. Prices are the usual AU winter range, and they move around a lot in the June to August sales.
The everyday low-voltage fleece throw
Most modern throws run low voltage, usually 12 or 24V through a transformer in the cord, which is safer than the old mains blankets and warms up in about ten minutes. A standard 160 x 120cm fleece throw sits at $50 to $90. Fleece is the honest default: soft enough, machine washable once you unclip the controller, and it heats evenly. The catch is that fleece pills over a season or two. If you only buy one, buy this and don't overthink it.
Sherpa or coral-fleece backing traps more air, so the throw feels warmer at a lower setting and stays warm longer after you switch it off. It does add weight and bulk, so it's better draped over an armchair than folded into a small basket. Expect $70 to $120.
Sunbeam is the brand I reach for when I can't be bothered thinking about it. Six heat settings, a one, three or nine hour timer, and controllers that are the least fiddly of the lot. Their antibacterial fleece throws land around $90 to $130. Not the cheapest, but the timer and the auto shut-off are the two features you'll actually use every night.
Goldair leans into settings. Some models give you nine heat levels against Sunbeam's three to six, so if you run hot and want a gentle background warmth rather than toasty, that granularity earns its keep. It's stocked everywhere here, roughly $60 to $110 for a throw.
There's a whole tier of budget throws at $40 to $60, and Kambrook is the reliable end of it. They heat fine. What you give up is timer length, washability, and controller quality. Fair enough for a spare room or a first try. One thing I'd insist on: check it carries the AS/NZS approval mark before you click buy, because the very cheap grey imports sometimes don't, and a heating element is not the place to gamble.
A standard throw covers one person. If two of you share the sofa, size up to 200 x 150cm or larger, and ideally get one with dual controllers so you're not fighting over the heat. These run $110 to $180. The dual-zone versions are worth the extra, because a single controller on a big throw means someone is always too warm and someone is always reaching for it.
A 100 x 150cm knee rug is the quiet hero if you work from home in a cold study. Over the lap at the desk it draws barely any power and keeps your legs warm without heating the whole room. Forty to seventy dollars. Mine lives on the office chair from May through August and it's the reason I don't run a heater in there at all.
Rechargeable and USB throws for the draughty corner
Battery and USB-powered throws have got genuinely usable in the last couple of years. No cord to the wall, so they suit a reading chair by a cold window, the caravan, or the kids' beanbag. The catch is runtime, most give you two to four hours on a charge, and they run smaller. Fifty to a hundred dollars with the battery pack. Handy, not a main-couch replacement.
If I had to keep one feature it'd be auto shut-off. A throw that cuts out after an hour or three is the difference between dozing off under it safely and not. Most mid-range models have it, the very cheap ones don't. If a listing doesn't mention a timer or shut-off at all, assume it hasn't got one.
Anything that lives on a couch gets grubby. You want a throw where the controller unclips and the blanket goes in the machine on a wool or gentle cycle. Most fleece throws do, but check the listing says machine washable rather than sponge clean only. Line dry it, never tumble, and never switch it on while it's still damp.
If the throw's going to live on the good sofa, the faux-mink and velvet-plush versions look far less like a medical device than a flat grey fleece. They cost more, $90 to $160, and can feel a touch less breathable, but they're the ones you'll leave out when people come over. I'd skip a busy print here and stick to a plain colour that matches the room.
Quick call, because people mix these up: a throw heats you on the couch, a fitted electric blanket goes under the sheet and heats the bed. They're not interchangeable. If the goal is the lounge in the evening, get a throw. If it's a cold bed, buy a fitted blanket in your actual mattress size. Plenty of households want both, and the throw is the cheaper and more flexible of the two.
Since everyone asks: a 60 to 120 watt throw on high for four hours a night is roughly two to four cents an hour at current AU electricity rates, so call it well under a dollar a week. That's the whole pitch, heat the person, not the postcode. One safety line worth repeating: no heated throw goes on a baby, and don't leave one running unattended with a pet who'll burrow in and kink the wiring. Unplug it when you get up off the couch.
