Maxwell incited some déjà vu in the seventh over with two strong boundaries, before the Aussies reached 50 at the eight-over mark – consistent with the speed of Afghanistan’s first 10 overs batting.
Maxwell and Marcus Stoinis lifted Australia to 70/3 at the mid-point of the innings, before Stoinis fell (11 off 17) just after drinks.
Tim David (2 off 4) was also out cheaply, but a Maxwell maximum to end the 13th over took the danger man to a half-century off 35 balls.
Just as Afghanistan lost marginal hope, Gulbadin Naib stepped up to the plate and tempted Maxwell into one outside the off stump, which was superbly snatched by Noor Ahmad behind point.
It was all on the hat-trick hero Cummins when Wade (5 off 7) top-edged an attempted sweep, leaving the Aussies at 108/7, needing 41 runs off 29 balls. But he couldn’t translate his form with the ball, swinging and missing to leave the Aussies in an even bigger hole with three overs to go and needing 36.
Afghanistan produced a masterclass in the field, converting every half chance into a scalp, which ultimately proved the difference. The wicket of Zampa trying to hit long down the ground had Australia all out for 127, 22 runs short of victory.
Gulbadin Naib picked up four wickets and took his own slice of history, becoming the first to do that in World Cup history – in both T20I and ODI cricket
The Afghans sealed one of the team’s most famous ever victories – their first over Australia. They have Bangladesh with their final Super Eight clash, while the Aussies have India.
