Normally I'd merge this in with the larger "Poker Site Suggestions" thread, but this is something of a special case with Australia having quickly pushed through legislation. Still surprised about that; after seeing your post I went to check back in on the NVG thread where things seemed to be going well last week, and...
I imagine the US-facing sites will be the place to start, but I don't know if access will be quite the same as for Americans; it will depend on which ones decide to go against the legislation - I imagine the situation is going to be a little fluid for the next month or two as sites decide what to do. Keep in mind that in the US, it's not online poker that is banned (in all but one state) - it's financial institutions processing transactions with online poker sites that is.
Edit to add: Let's keep discussion about circumventing the ban out of this thread; we don't usually allow discussion of ways to break site T&Cs. Not only that, it's probably smarter for those who decide to take such routes that their methods are not discussed in public on a high profile poker forum.
