Defending Champions Australia are already in the quarterfinals but their spinners have struggled so far in the tournament and they would be keen to prove their worth when they meet Canada in their penultimate group A World Cup match on Wednesday.

From forgotten man to World Cup starter, Australian off-spinner Jason Krejza will return to the scene of his greatest triumph when the reigning champions face New Zealand on Friday.

Jason Krejza is the only frontline spinner in the Australian World Cup squad but former Test skipper Allan Border does not see much of a role for him in the side.

Australia were today dealt a severe blow ahead of their World Cup title defence after batting mainstay Michael Hussey and spinner Nathan Hauritz were ruled out of the mega-event due to injuries.

Jason Krejza and Western Australian all-rounder Adam Voges have been called into Australia's squad for Sunday's final match of the one-day series against England in Perth.
