Australia is part of the "citizens of the crown" in that we are part of the Commonwealth. The reason we travel far easier, is that Australia is an incredibly young country (1901), so most people are < 2 generations away from European ancestors. This makes visa's quite easy. We also have a pretty great deal with the US, with the E3 visa, which is basically a private pool of visas only available to Australians. Re: US citizens travelling to the UK, I don't think there are very good systems in place for that. I think you would be better off with the wider EU (Swizterland, Germany, France, Netherlands, Denmark are pretty decent from a tech perspective)
