So no, to the extent that one can be confident of experimental data, I'm pretty confident that we are seeing IPv6 preference in AU of around 0.83% of users at the moment, and an IPv6 capability of around 4.1% of all users (the higher capability is predominately 6to4 auto-tunnelling performed by Windows systems, quite probably without the knowledge of the end users).

One of the hidden things is what happens to traffic that isn't from a set of eyeballs.
I know that George Michaelson commented that APNIC saw a marked increase in IPv6 traffic to their DNS servers (incl root server) when Internode move to their new resolver cluster back in late 2009/early 2010. These clusters were IPv6 enabled for customers, but also preferred IPv6 on the backend, so suddenly as much of Internode's DNS resolver traffic as it could moved preferentially to IPv6.
So, increasing IPv6 traffic isn't always just about the eyeballs, it's also about traffic that suddenly switches when you move your routers/servers/applications across.
