(news.com.au) - Australia have been knocked out of the T20 World Cup as a wild game between two minnows decided their fate amid a blatant act of cheating.

Afghanistan is through to the T20 World Cup semi-finals after winning a wild rain affected game against Bangladesh that knocked Australia out.

In a game that featured multiple rain delays and questionable delaying tactics, Afghanistan scored 5/115 off their 20 overs and Bangladesh were set a target of 114 runs from 19 overs under the Duckworth Lewis method.

In a thrilling run chase, Afghanistan bowled Bangladesh out for 105 with just seven balls remaining to win their second Super 8 game and leapfrog Australia in the Group 1 standings.

Talismanic legspinner Rashid Khan finished with figures of 4/23, leading another superb bowling display from his side.

The result means Afghanistan will play South Africa in the first semi-final on Thursday, before India take on England in a blockbuster semi on Friday.

Australia has been knocked out in the group stage in consecutive T20 World Cups and their quest to hold every men’s and women’s trophy in world cricket is over.
