England sealed their place in the final of the women's quadrangular Twenty20 series with a 22-run over Australia.
Captain Charlotte Edwards was once again superb with the bat, her run-a-ball 43 contributing to a competitive 136-6 at Bristol.
Australia's riposte centred around Meg Lanning (33) but a middle-order collapse saw the tourists lose six wickets for just 25 runs.
England play India in their final round-robin match on Sunday at Taunton.
But the hosts already have eight points following a comprehensive eight-wicket win against New Zealand in their opening match, and New Zealand's 25-run win over India in Saturday's second game at Clifton College ensured England will play in Monday's final at the Rose Bowl.
World Twenty20 champions Australia opted to bowl first at the County Ground, only to see Edwards and Laura Marsh compile a promising open-wicket stand of 59 for the first wicket.
Marsh was the first wicket to fall on 28, bowled by off-spinner Erin Osborne in the ninth over attempting an unconventional shovel over her shoulder.
Claire Taylor fell soon after and when Edwards was caught by Alex Blackwell off Osborne for a run-a-ball 43 in the 13th over, England's innings was in danger of stalling.
But an enterprising 25 from wicketkeeper Sarah Taylor, assisted by Lydia Greenway (18) and Arran Brindle (15), injected fresh impetus into the innings as England finished on 136-6 from their 20 overs.
Australia's riposte was swift, but Holly Colvin struck with her first delivery when opener Leah Poulton top-edged a simple catch to Claire Taylor at short fine leg in the seventh over.
And a superb direct hit from an under-arm throw at full stretch from left-arm spinner Colvin accounted for Alex Blackwell.
A series of intelligent strokes on both sides of the wicket from Lanning ensured Australia were in touching distance of the run-rate, but her dismissal in the 15th over - caught behind for 33 from Danni Wyatt's first delivery - sparked the collapse.
Poor running between the wicket contributed to three avoidable run-outs while off-spinner Wyatt cleaned up the tail.
"It was a great team performance. Charlotte and Laura got us off to a great start again and we kept the momentum up," said Sarah Taylor, who was named player of the match.
"There was a real buzz in the field, the spinners really turned the screw and were backed up by the fielders.
"It's so good to play in front of a crowd - it really boosts you every ball when there is a cheer."
