Australia 163 for 5 (Mooney 82) beat South Africa 162 for 7 (Kapp 75)

The opener's 55-ball knock helped Australia get past the visitors' 162 for 7 with five wickets in hand and four balls to spare in Hobart

South Africa forced a deciding T20 game after notching their first victory over Australia in any format on Sunday to level the ledger at 1-1.

Mooney, who hit an unbeaten 72 in the opening game, struck the ball cleanly from the outset and finished with 11 fours and one six. Fellow opener and Alyssa Healy failed to fire as did Ellyse Perry who was elevated to number No.3.

After her team was sent in to bat, Kapp helped South Africa recover from a wobbly 28 for 3 in the fifth over.  The allrounder shared an 80-run partnership from just 57 balls with Anneke Bosch, who supported well with 21.

Kapp's score surpassed her previous best of 56 and came after she was dropped on 19 in the outfield.  She was dismissed in the 17th over when Tahlia McGrath snuck a slower ball that crashed into the stumps.

Australia's Grace Harris was in the action early, taking two catches and running out Sune Luus with a direct hit.

Chloe Tryon chipped in with an important 26 from 16 balls late in the innings before being caught and bowled by spinner Georgia Wareham in the 18th over.

Nadine de Klerk also swung hard at the death, finishing with an unbeaten 20 from 11 balls including two fours off the last three deliveries.

Wareham was Australia's most economical bowler with 1 for 25 from four overs, while quick Darcie Brown (0 for 27 from two overs) copped some stick after sitting out the previous match.
