Tait wasn't originally expected to play a large part in the World Cup, however with Brett Lee ruled out for the tournament due to an ankle injury, a relatively inexperienced Tait assumed Lee's mantle as the spearhead of the bowling attack. Despite the added pressure, Tait performed to much acclaim in the World Cup, finishing the tournament as the equal second leading wicket-taker with 23 wickets at an average of 20.30. Tait's best efforts of the tournament included a Man of the Match performance against England in a Super 8s match at Antigua in which he claimed 3/41 off 10 overs, as well as 4/39 off 10 overs, his best One Day International figures at the time, against a strong South African team in the semi-final at St Lucia. While Tait went wicketless in a rain affected Final against Sri Lanka, Australia won the match and Tait's efforts throughout the tournament helped Australia secure their third consecutive and fourth overall Cricket World Cup title in the "most dominant campaign" by a team in World Cup history.
