Australia's wealth is from its natural resources. Originally farming, then gold, coal, oil, and uranium. Britain has some natural resources in the North sea, but London has been a centre of intellectual wealth for hundreds of years: before there were startups, there were the Rothschild's, banks, and every other kind of trader. Man Group started the first hedge fund in the world in London 200 years ago based on storms affecting the sugercane crop for their Royal Navy rum contract. Australia is still at the selling sugarcane stage.

So while the UK is a little more cynical than the US, it still appreciates the value can be created intellectually because it has that history. Australia doesn't, because money is made by digging things up and selling them. I met and worked with some incredibly talented technical people in Oz - Damien from BSD/ipfw, Skud from Perl, lots of SA folk from Usenix - but the general business community is very wary of tech.

There are key difference b/w the US, UK and Aus (native speaker here) with respect to business. I perceive the US as risk-takers with access to deregulated finance. The UK is risk-adverse with sophisticated finance. In Aus we have a combination of risk aversion and what I'll term, "dumb-money".
