Three wickets from Ash Gardner has seen Australia seal victory in their three-match T20 international series against Bangladesh overnight.

After going wicketless in the first T20 fixture between the two sides on Sunday, Gardner took 3-17 from her four overs in the visitors' comfortably 58-run victory.

In response to Australia's hefty 8-161 Bangladesh started in strong fashion, reaching 0-27 after three overs before Australia's spin trio of Gardner, Sophie Molineux and Georgia Wareham tightened the screws whilst taking seven Bangladesh wickets.

Gardner struck in the 7th over of the chase, removing Bangladesh number 3 Sobhana Mostary (5-from 8), who was stumped after an attempted slog across the line.

Returning later in the innings to complete her spell, the Muruwari woman required no assistance in removing both Fahima Khatun (15 from 18) and Shorna Akter (21 from 17) after clean bowling both in the 15th and 17th overs respectively.

The allrounder was well supported by the left arm spin of Molineux (3-10) and Wareham (1-24), with Bangladesh ending 9-103 after 20 overs.

Opener Dilara Akter was the home side's best, scoring 27 from 25 balls.

Earlier in the match Gardner missed out with the bat, contributing just 5 (4) after being caught and bowled by leg-spinner Fahima Khatun.

Australia however posted a healthy 8-161 on the back of promoted Georgia Wareham, who scored her maiden T20I half-century (57 from 30), with opener Grace Harris contributing 47 (34), the pair putting on 91 for the second wicket.

At one point on track for a 200-plus score, Australia were limited after losing 7-55 with left arm seamer Fariha Trisna picking up four wickets, including a hat-trick from the final three balls of the innings.

Australia will look to make a clean sweep of their one-day and T20 tour of Bangladesh in the final match of the series on Thursday.
