Cora Staunton's two-goal haul helped Greater Western Sydney to a season-opening victory over Gold Coast at the Great Barrier Reef Arena.

The Mayo woman's two goals proved vital as the Giants came out on top in the hard-fought victory against the Suns, winning 36 (5.6) to 21 (3.3).

It was a landmark day for Staunton who, aged 40, became the oldest player in AFLW history.

Cork native, Bríd Stack, made her long-awaited AFLW debut for the Sydney side, playing alongside compatriot Staunton, as well as Olympic gold medallist Chloe Dalton.

Playing in the defence, the multiple All-Ireland winner put in a commanding performance having missed out on last season as a result of suffering a broken neck in a pre-season game.

Elsewhere, Sarah Rowe kicked the first Irish goal of the campaign as Collingwood began their campaign with an impressive 44-25 victory over rivals Carlton.

The former Green and Red star's goal helped her side to a 19-point win, however, the Pies were hit with a bad injury as one of their top players, Brianna Davey, appeared to seriously damage her knee.

Rowe also made a significant contribution throughout the encounter picking up 21 disposals throughout the derby game.

In Sunday's other game, Tipperary's Orla O'Dwyer was one of the top performers for the Brisbane Lions in their season opener against the Adelaide Crows.

O'Dwyer impressed throughout, picking up 21 disposals, however, she came out on the losing side as her Queensland outfit were beaten 39-9.

County Clare's Ailish Considine was not in action for the Crows on the opening weekend of the AFLW season.
