I don't really see what changes they need to make. I'd stick with Hussey. He's not looked particularly out of touch, consistently made starts and bar a couple of misjudged leaves he's looked ok, and the innings here has been very good. I'd stick with the bowlers, and think they've performed well, they've just lost the key times in the series. All the close moments have seemingly gone England's way. I don't think Australia need to panic and make wholesale changes, they still look a decent side, the series stats prove that. I do see them eventually going to Jaques and Hughes as the opening partnership, as I'm not convinced with Watson and Katich, but they should be stuck with for a little while longer.
