Lydia Greenway falls first ball, nicking one to the wicketkeeper - Farrell is on a hat-trick!

Captain Edwards opens the face and guides Farrell for four through third man - but then perishes when she holes out to mid-on where the recalled Nicole Bolton takes the catch.

Edwards finds the boundary for the first time, while a single takes her to eight - Taylor has two.

New batter Sarah Taylor is off the mark with a single off her first ball, Edwards adds a single, and Taylor doubles her score by nicking the strike.

"A real opportunity for Lauren Winfield goes begging, especially with this being England's last game ahead of the World Twenty20 in Bangladesh."

Rene Farrell takes the second over, another single from Edwards but then Winfield perishes for a second-ball duck as she chips a catch to backward point.

Teenage pacer Holly Ferling takes the first over, and Edwards gets England going with a single to fine leg.

It's Sydney, Jim, but not as we know at. For today's T20 games are not in the genteel surroundings of the Sydney Cricket Ground, but at Stadium Australia - also known by a variety of sponsor names, but probably better known to you as the Olympic Stadium from the 2000 Games, and the venue of the 2003 Rugby World Cup Final. (Any Australians reading this are welcome to look up the result of that game).

There's a change in the England batting order from the last game as Charlotte Edwards is opening with Lauren Winfield rather than Danielle Wyatt.

News from the middle is that Charlotte Edwards has lost the toss - Australia have elected to field first.

England have the luxury (!) of 12 fit players rather than 11 from their 15-strong squad, and recall the fit-again Jenny Gunn for Amy Jones. Australia bring in Nicole Bolton and Megan Schutt for Jess Cameron and Julie Hunter.

Morning, everyone. The finish line is in sight - after a gruelling few months, today sees England's men and women lock horns with Australia for the final time on this tour.

First up is the final match of the multi-format Women's Ashes series (which England have already won) - the third and final Twenty20 international from Sydney.
