Penrith utility forward Scott Sorensen is given the green light to play on Sunday night, as the Melbourne Storm show confidence in the least experienced player in 30 years to feature in a season decider.

Richmond ignores a lengthy lightning delay to press its finals case with a dominant 36-point win over Collingwood, while Jasmine Garner helps flag favourites North Melbourne maintain its undefeated record in convincing fashion.

Penrith have a host of their junior products playing on grand final day while Melbourne have one in Newtown Jets forward Jordin Leiu and the tough forward is ready to represent his home on the game's biggest day. 

The Sharks weren't supposed to make the NRLW grand final just like Annessa Biddle wasn't supposed to dominate one of the game's best attacking players last week, but things have a habit of going the Cronulla centre's way. 

Without Matthew Dellavedova, Melbourne United dominate the Perth Wildcats, who missing stars of their own.
