I would wait a couple of days - NFP this friday, which could turn that view completely on its head !
If that were my view I would probably be selling EURUSD, but that is just me. As you say, AUD is commodity/stock related, so doesn't always move quite like the EUR or GBP.
Unless you have a surefire trade signal (the best example I can think of here is 10cents and using something like MA envelopes for longer-term trades - have a look at weekend chart threads) - then I would say choose one or two currencies, know them well, get to know how much they move on any typical day, where their support/resistance levels are, how they move in relation to news/stocks/etc.
There is enough to think about without chopping and changing all the time - and some of my worst "give back all the profit" trades are when I change currencies without really planning what I am doing.
