Ibrahim Zadran scored Afghanistan's first World Cup hundred as the tournament's surprise package team made 291-5 against five-time champions Australia in a group match in Mumbai on Tuesday.

The 21-year-old opener's 129 not out was the cornerstone of Afghanistan's highest World Cup total, surpassing their 288 against the West Indies at Headingley in 2019.

It also left Australia facing a record chase, with the most they have made batting second to win a World Cup match their 287 against New Zealand in a 1996 quarter-final in Chennai.

And they will have to get those runs without star batsman Steve Smith, ruled out after suffering from vertigo.

Australia initially found wickets hard to come by after losing the toss in a match where a win would guarantee them a semi-final place.

But they largely kept Afghanistan -- in semi-final contention themselves following four wins in seven matches --in check until Zadran and Rashid Khan (35 not out) shared an unbroken stand of 58 in 28 balls.
