After 15 straight wins in the T20 World Cup, the Australians, without injured captain Alyssa Healy, never quite managed to fire after being put in to bat as they mustered 5-134 against some tight South African bowling.

The ever reliable Beth Mooney top-scored with 44 off 42 balls but even the masterful opener couldn’t really break the shackles, as only a late blitz from Phoebe Litchfield (16no off nine balls) and Ellyse Perry (31 off 23) took them to a defendable target.

But South Africa, determined to glean revenge for their T20 final defeat on home soil against Australia last year, made the target look simple with the brilliant Anneke Bosch (74no off 48 balls) crashing the second-fastest 50 and biggest score of the tournament.

She was aided by skipper Laura Wolvaardt (42 off 37) in a thrilling 96-run partnership as the South Africans, never seemingly under pressure at any stage, reached their target on 2-135 with 16 balls remaining.

In the final, the South Africans will take on West Indies or New Zealand, who meet in the other semi-final on Friday.
