Multiple nights, and often in less-travelled areas of Australia where there's no guarantee other people will find us if something goes wrong. It would be a bit insane carrying 10kg base weight on a day walk unless you had kids.

That weight is the maximum and (in addition to everything above) includes a 70L pack, tent, sleeping gear, poles, rain gear (the weather is treacherous here), a stove, thermals/scarf/beanie for the cold (some places in the Victorian Alps like to dump snow on you in the middle of summer), a hat and sunscreen, spare socks, a toothbrush that I haven't cut in half and toothpaste that hasn't been dried out, light source and batteries, water filter, battery pack on longer trips, dry bag if we're doing a deep river crossing, etc.

I take out what I won't need, swap in less rugged gear when there's lower risk, and usually end up somewhere between 6kg and 9kg base weight. I could probably shave off another kg or even two, but at some point I'd be sleeping under a tarp in Victoria's famously horizontal rain or ditching safety gear.
