His international career was revived for the 2011 World Cup when
Nathan Hauritz and Xavier Doherty were ruled out with injuries, having
made his ODI debut late in the home summer against England. Managed
five wickets in eight games at the World Cup, but was given a chance
to duel for Test berth during the winter Australia A tour of Zimbabwe.
The spinners' spots for Sri Lanka were instead taken by Nathan Lyon
and Michael Beer, and most of Krejza's opportunities with Tasmania
this summer have been in one-day cricket. On Test debut in Nagpur in
2008, produced astonishing figures of 8-215 and finished with 12
wickets for the match, the second-best match figures on debut by an
Australian after Bob Massie. Played one more Test, against South
Africa in Perth that summer. An attacking off-spin bowler, his
struggles for consistency meant Hauritz was then preferred as a more
containing option. Moved from NSW, where there was intense competition
for spin places, to Tasmania during the 2006-07 season.
