I will stick to deciders from the NRL era until present since this is only a Top 5 list & competition is too stiff, though I do have a bit to say about a few pre-1998 GF’s I will mention at the end.
1. Panthers 18 Roosters 6 (2003)
-I hate to say it because we were on the losing end, but there’s never been a more exciting or brilliant GF than 2003, IMO. A magnificent performance from both sides to the end - if only Freddy had been fit, perhaps things would’ve turned out differently.
2. Roosters 26 Sea Eagles 18 (2013)
-What a mockery these two teams made of neutral complaints that this would be a decider no one cared about. These two had already fired their warning shot for a great Grand Final in Week One of the Semis, & there’s almost nothing the match didn’t have. Jennings’ miracle four-pointer was as sweet a cherry atop a flawless match as anyone could’ve asked for. I was shaking so much I dry-reached in the toilet when Matai scored.
3. Sharks 14 Storm 12 (2016)
-Even as a neutral I found myself shaking in the final few minutes of this one. The final passage of play was almost as intense as the finish to the 2015 GF, & the rest of the match was of an overall higher quality than that game. This is also surely the GF which went on the longest after the full-time siren. The Storm had a chance to win it for what felt like a full minute after the bell. Fantastic stuff.
4. Roosters 14 Raiders 8 (2019)
-A funny thing happened to me during the second half of this match - I recalled a conversation I’d had with a Raiders-supporting mate the week of the 2018 GF. I told him whatever happened, he would never, ever see the Raiders win a GF in his lifetime. Then, this happened just twelve months later. An almost perfect pitch battle from start to finish, I’ll never forget it.
5. Cowboys 17 Broncos 16 (2015)
-Although this was overall a great Grand Final, & deeply satisfying to me personally (I’d waited my whole life to watch the Broncos filth lose a decider), I do think it’s over-rated by people. It was a scintillating first half & a once-in-a-lifetime conclusion, but it can’t be glossed over that the entire second half (nearly 50% of the contest) was a fairly dull slog. Still an overall great one, just not quite as perfect as people suggest.
Just missing out:
Storm 20 Dragons 18 (1999).
-So far as I’ve been able to determine, the biggest comeback ever in a GF, & neck & neck with 2015 for the greatest finish to a GF ever witnessed. There were some great periods of play, but just a few too many dull patches to quite take up a Top 5 spot.
I want to say something perhaps controversial. The 1989 GF just isn’t anywhere near as great as people say for mine. Not to say I didn’t enjoy it, but it wouldn’t be close to #1 IMO. I also do not consider the 1997 GF - that was a very, very exciting match, but the Knights abused PED’s to achieve that result & nobody talks about it. That takes it out of the equation for me.
