Australia have won the toss and will bat first as they aim for a third-straight ODI win in the Ashes series against England.
The hosts have brought in legspinner Georgia Wareham at the expense of quick Darcie Brown on a drier-than-expected pitch at Ninja Stadium in Hobart.
Australia won the first ODI in Sydney by four wickets and the second by 21 runs after defending a meagre 180 at Melbourne’s Junction Oval.
Alyssa Healy’s chargers hold a four-points-to-zero lead in the multi-format series, with each of the three ODIs and the following T20s worth two points.
The series-concluding day-night Test at the MCG is worth four points.
Australia are chasing a sixth-straight Ashes series triumph and need eight points to retain the trophy.
England have selected an unchanged line-up.
AUSTRALIA: Alyssa Healy (capt), Phoebe Litchfield, Ellyse Perry, Beth Mooney, Annabel Sutherland, Ashleigh Gardner, Tahlia McGrath, Alana King, Kim Garth, Megan Schutt, Georgia Wareham.
ENGLAND: Tammy Beaumont, Maia Bouchier, Heather Knight (capt), Nat Sciver-Brunt, Danielle Wyatt-Hodge, Amy Jones, Alice Capsey, Charlie Dean, Sophie Ecclestone, Lauren Filer, Lauren Bell.
