Subiaco will unleash a livewire forward line on East Fremantle in another bid to keep their colts premiership hopes alive.

Electric forward Lance Collard kicked five goals to swing their elimination final against West Perth — a game they trailed until piling on six unanswered majors in the third term.

He combined for seven goals with top bottom-age prospect Malakai Champion in the blistering performance that put them two wins away from a grand final.

The Falcons largely quelled the influence of gun midfielder Tyler Senge and instead, it was the returning Riley Wills that got on top of them. But it was the forwards that made the difference.

East Fremantle have made no changes to the team that lost a qualifying final to Claremont on Sunday.

The Sharks were left on the back foot by a scoreless opening term against the Tigers, a push back into the game after half-time falling short.

In a contrast of styles, the Sharks will look towards emerging tall Jack Cocking and fellow towering target Griffin Vladich. The pair combined for two goals in last weekend’s defeat.

Cocking has been a revelation late in the season in the Sharks’ push towards the finals. He has kicked one goal in each of his past four games, after bags of six, five and two four-goal hauls to finish the home-and-away season with 43 majors.

Minor premiers Perth make their first appearance of the finals after earning the week off in a clash with Claremont on Sunday.

It is the second time the two sides have met in three weeks, the Demons holding off their nearest rivals to secure top spot in the final round of the season.

The winner of that game will jump straight into the colts grand final.
