The unbeaten Fremantle has sent an ominous warning to its AFLW rivals, producing a ruthless performance to comfortably account for Gold Coast in a bruising semi-final on Saturday.

Freo were a class above their opponents, moving through the gears throughout the afternoon on their way to a resounding 70-point victory at Fremantle Oval.

The 12.8 (80) to 1.4 (10) win sees Fremantle set up a highly anticipated preliminary final bout with Melbourne next week, while ending the impressive debut campaign of a plucky Gold Coast side.

Kiara Bowers was again sensational for the hosts, racking up 22 disposals and 14 tackles in a best on ground showing, while Ebony Antonio (20 disposals, one goal) and Kara Antonio (19 disposals, seven marks) were also influential in a dominant display.

Typical of its brave maiden AFLW season, Gold Coast was stringent defensively throughout a hard-fought opening half and looked to be well and truly in the contest before a late Fremantle flourish on the stroke of the main break broke the game open.

Lively forward group Gabby O'Sullivan, Kate Flood, Sabreena Duffy and Gemma Houghton all got among the action to kick multiple goals, while a strong pack mark and a composed finish from Roxy Roux extended the home side's advantage to 27 points at the interval.

That lead continued to build throughout a routine second half for Fremantle, who kicked 10 consecutive goals after quarter time to rub salt into the wounds of the tiring Suns and ease into the next week of the finals.
