David Warner (7), Mitchell Marsh (15) and Steven Smith (4) all departed cheaply as Australia slipped to 47/3 inside the opening seven overs, with Mohammed Shami and Jasprit Bumrah taking the wickets.
But a superb partnership between Head and Marnus Labuschagne won it for Australia, with Head hitting a stunning century and Labuschagne playing the foil at the other end, bedding in with a resolute half-century of his own.
Travis Head was the star with the bat, hitting an inspired century to win Australia’s men their sixth ICC Cricket World Cup crown.
