Sydney has sharps bins in public loos. It seems like a good idea to me, but I don't know if Australians like it, or if it actually works.

Here's a description: http://www.cityofsydney.nsw.gov.au/community/health-and-safe...

And here's a map:

I'm in Australia and don't mind if there are sharps bins. They're easily ignored and generally placed high enough that curious kids don't get themselves in trouble. Whatever community/health experts deem best is fine by me.

I don't think it's an issue for most people. The sharps bins look very medical so it is easy to forget that the users are potentially throwing away things other than insulin needles, especially if you're not wandering around looking to be angry about the fact that people inject drugs.
