Openers Alyssa Healy and Beth Mooney have helped power Australia to 5-165 in their women’s World Twenty20 opener against Pakistan in Guyana.

After Healy and Mooney whacked Australia to 0-58 from the opening six-over power play against the spinners, the tournament favourites slowed when both holed out for 48.

Healy’s knock was particularly electric, coming off just 29 balls as she hit the ball powerfully through the leg side and struck a massive six straight down the ground in the game’s opening over before falling to seamer Aliya Riaz at long on.

Mooney’s innings came from 39 balls after she was dropped on just two at cover in the fourth over before the ball eventually crossed the rope.

But she went for one too many as she attempted to lift the tempo in the middle overs, also finding the fielder at long on when she looked to take on Nashra Sandhu.

Captain Meg Lanning then closed the innings with 41 from 34 balls, while Ashleigh Gardner chipped in with 13 off 10.

It means Pakistan’s women will need to chase down the biggest successful run chase in their team’s history to claim victory on Saturday (AEDT).

Australia coach Matthew Mott opted to stick with the same team that beat Pakistan through the majority of their 3-0 sweep in Malaysia last month, overlooking offspinner Jess Jonassen, who is returning from a knee injury.

The form team headed into the tournament, Australia aim to reclaim the trophy they won three times straight between 2010 and 2014 but dropped in 2016.
