The Adelaide Crows will face the Brisbane Lions in next Saturday's AFLW Grand Final after semi-final victories over Melbourne and Collingwood respectively.

Tipperary's Orla O'Dwyer impressed for the Lions as they squeaked past Sara Rowe's Collingwood by just four points, 45-41.

O'Dwyer scored a goal and had 11 disposals, among the highest on her team, while Rowe had seven disposals for the 'Pies.

It was a gripping affair at the Gabba, as the Lions raced into a 10-point half-time lead, only for 'Pies to fight back to a two-point deficit heading into the final quarter.

The Lions will have to travel to the Crows' den in Adelaide, however, after the two-time champions earlier defeated Melbourne 33-15 at Adelaide Oval.

Clare inter-county star and RTÉ Sport columnist Ailish Considine was emergency reserve for the Crows after an injury-impacted season, but she will hope to come into the reckoning ahead of the decider.

Ebony Marinoff (35 disposals and 13 tackles) and Anne Hatchard (27 disposals and one goal) starred for the Crows, who may be without captain Chelsea Randall after she suffered a suspected concussion.

Adelaide, winners previously in 2017 and 2019, will be looking for a third title, while the Lions are looking for their first win at the third time of asking.
