Why does Australia need 5 bowlers? That's like saying Australia needs reverse swing to win, or any of the other things Australia has never needed in the past. Australia hasn't had a world class all-rounder since the Davidson and Benaud days in the 50s and 60s, and even then they often only picked 4 bowlers. Even when they didn't have a reliable spinner, Australia played 4 quicks. All through the 90s with Warne, Australia supported him with 3 quicks. Why is it that just because England have Flintoff Australia suddenly desperately need a 5th bowler?
Having Clarke able to bowl would be handy, but really it doesn't matter. If McGrath, Warne and Kasprowicz play as well as they did all of last year and Lee plays like he has this series and Australia hold most of their catches, Australia will do well with the ball anyway. Having a fifth bowler would have helped with hiding Gillespie, but it's not a necessity, which is why Australia has done it about 3 times in the last decade while dominating more comprehensively than any team ever has before.
The real problem is batting, right now. If Australia bat first and make a big score, the rest will sort itself out as it usually does when you have two all-time greats in the team.
Look, Lady McBeth, I've never cared where players come from
