For 2025, several major “grand finals” took place in different sports, and which one you mean changes the answer. Here are the main ones people usually refer to when they just say “the grand final”:

  • Geelong Cats
  • Brisbane Lions

The match was played at the Melbourne Cricket Ground on Saturday, 27 September 2025.

Super League Grand Final 2025 (Rugby League)

  • Hull Kingston Rovers
  • Wigan Warriors

This was played at Old Trafford in Manchester as the championship decider for the 2025 Super League season.

Quick Scoop style answer

If you’re asking what most Australian fans mean by “the grand final 2025” without extra context, they’re usually talking about the AFL:

  • Who is in the grand final 2025?
    • Geelong Cats vs Brisbane Lions (AFL)
  • Other big “grand finals” in 2025:
    • Hull KR vs Wigan Warriors (Super League rugby league)

If you had a specific sport in mind (AFL, NRL, rugby league, another code, or even esports), tell me which one and I can narrow it exactly to that grand final.
