Nathan Bracken wasn't included.
Bracken still has a decent amount of years in him and his style of bowling would be ideal for the subcontinental conditions that Australia will face in the 2011 World Cup. Bracken would also solve Australia's issue of leaking runs during the last 10 overs of an innings. Sure, it hasn't been too problematic of recent, but it probably will be when we face teams like India and South Africa in major games.
The issue with Bracken, though, is who to drop to get him back in? Bollinger, Harris, and Johnson have all been taking wickets, as did McKay when he played. Then there's still Siddle and Hilfy out, and the possibility of Brett Lee making a return for the World Cup. There's not really any place for Bracken.
Not too surprised with it, only McDonald raised my eyebrow.
I'm really surprised McDonald kept a contract too. If he'll play anything, it'll only be Test matches, and with the emergence of Watson, the injury of Callum Ferguson healing, and the possibility of Steve Smith in the side in the not-too-distant future, there's really no place in the side for him in the middle order, while Harris, McKay, Johnson, and Bollinger will all beat him to a paceman's spot. Then there are the injured Siddle and Hilfenhaus.
