Certainly in Sydney. I notice because I think they're over priced at AU$250, and I'm surprised how many school kids have them. I would lose them in a week.
Heaps in Melbourne as well. Personally I find them daggy; if they're anything like the earphones included with the iPhone 3 they'd fall out of my ears if I just turned my head.
Samsung Buds OTOH stay in (and don't have the daggy bits hanging out).
I also have had problems with Apple's wired earphones staying in, so I was skeptical of the AirPods. But they stay in great. Turns out that most of the problem was the weight of the cord.
