The Queensland Under-18 women's team will take on NSW Metro tomorrow in a semi-final as they work towards defending their National championship T20 crown.

Queensland accounted for Tasmania and a maroon-tinted Northern Territory team yesterday to be undefeated in the pool games.

A classy half century by Georgia Voll (83) and tight bowling from Clodagh Ryall (2-11), Charli Knott (2-13) and Grace Parsons (1-13) helped Queensland overcome a dogged Northern Territory, which had Queenslander Jess Bradley (32) top score.

A 113-run opening stand by Ellie Johnson (52) and Voll (43) set Queensland on a winning path as they made 7-132 against Tasmania. 

Ryall (3-0) and Julia Cavanough (2-1) then combined to cut a swathe through the Tasmanian batting to dismiss the host team for 41.
