England have dropped Sophia Dunkley for their T20 World Cup warm-up against Australia, promoting Amy Jones to open the batting. Dunkley's place was vulnerable after scoring just 98 runs in six innings against New Zealand and India, with a highest score of 26. Both openers fell cheaply, with Jones caught at mid-off for two and Danni Wyatt-Hodge bowled for four.

Captain Nat Sciver-Brunt replaces Dunkley in the top six, batting at three in her first international appearance of the summer. The in-form Alice Capsey remains at four, suggesting this could be the line-up for England's tournament opener against Sri Lanka on Friday. Sciver-Brunt is playing as a specialist batter while continuing her recovery from a calf injury.

Australia won the toss and chose to bowl first at Sophia Gardens in Cardiff. England also face India in their second warm-up match on Wednesday. The match provides both teams with valuable preparation ahead of the main tournament. England will hope to find better batting form before their opening World Cup fixture.
