We've asked some south-west football identities who they think will win the 2020 decider at the Gabba - Richmond or Geelong?

They're tipping a close decider at the Gabba on Saturday night.

Role: Potential AFL draftee

Tip: Richmond by between one and 15 points

Norm Smith Medal: Bachar Houli just because he plays his role every time Richmond cross that line and he's obviously a very talented backman.

Why: Geelong first goal. Gary Rohan, only say this because I believe he feeds off moments like these. Richmond to win with the margin being between one and 15 points. Obviously both tough teams going into a grand final involving past premiership players who have experienced this kind of level.

Role: Essendon footballer

Tip: Geelong by 17 points

Norm Smith Medal: Mitch Duncan

Why: They have been playing so well together and are extremely hard to score against.

Role: St Kilda AFLW player (drafted earlier this month)

Tip: Geelong by 13 points

Norm Smith Medal: Patrick Dangerfield or Dustin Martin

Why: I am tipping Geelong because I barrack for them but if they are able to get on top of it in the middle and deliver it well to Tom Hawkins, I believe they will be able to win.

Role: Allansford coach

Tip: Geelong by three goals

Norm Smith Medal: Rhys Stanley

Why: I'm a Cats supporter so I'll be tipping them but I also think that having lost a few finals over recent seasons they will have a strong desire to win and playing at the Gabba seems to suit them.

Role: Hamilton Kangaroos coach

Tip: Geelong by four points

Norm Smith: Patrick Dangerfield

Why: I expect a very tight, close grand final. In fact, we have got the grand final the majority had hoped for. Geelong has a slight advantage forward of the ball and defensively have the capacity to restrict Richmond's key forwards.

Role: Kolora-Noorat coach

Tip: Geelong by 16 points

Norm Smith: Mitch Duncan

Why: The Cats are in great form and I think Patrick Dangerfield up forward could cause some headaches for Dylan Grimes and the Tigers' defenders.

Role: Port Fairy coach

Tip: Richmond by 22 points

Norm Smith: Shane Edwards

Why: Very consistent brand which stacks up in finals and any weather conditions. They rarely get too far behind on the scoreboard when the game isn't on their terms and then hurt opposition when the tide turns.

Role: AFL Western District operations manager

Tip: Richmond by 23 points

Norm Smith: Tom Lynch, has had a tough year and feel this will spur him on in the big dance to dominate.

Why: Heart feels Geelong but brain says Richmond. Both teams are packed with star power but can't see Geelong stopping Dusty Martin.

Role: Ex-South Warrnambool women's coach

Tip: Richmond by nine points

Norm Smith: Dustin Martin because I want him to be the first player to win three but also Bachar Houli because he has been robbed twice before.

Why: I think we might have Geelong for pace and Jack (Riewoldt) is ready for a big game.

Role: Warrnambool coach

Tip: Richmond by 12 points

Norm Smith: Bachar Houli

Why: Their pressure at the contest combined with two talls up forward supported by crumbing goal-kickers and a solid defence will be just enough. Their pressure should hinder the Cats from controlling the game too much and limit their uncontested marks.
