Milestones

• Long standing Roosters fullback Anthony Minichiello played his sixth grand final for his club after having previously featured in every premiership decider they have reached since 2000, although his only victory came from 2002.^[4] Were the Roosters to lose the game he would have been the first player in the history of Australian rugby league to lose five grand finals.
• Jamie Lyon, Brett Stewart, Glenn Stewart, Steve Matai, Brent Kite and Anthony Watmough all played their fourth grand final together, after having previously appeared in their past three appearances for Manly in 2007, 2008 and 2011.

1st half

Manly began strongly and had control early on. Pressure led to Roosters five-eighth James Maloney kicking out on the full, and a tackle from his opposing number Kieran Foran on back-rower Sonny-Bill Williams led to a dropped ball and possession for the Manly side, which quickly led to their first try, scored by winger Jorge Taufua. Captain Jamie Lyon missed the conversion, making it 4–0 to Manly-Warringah, however a penalty a few minutes later led to a scoreline of 6-0 by the 17th minute.^[1] The Roosters came back to score through winger Daniel Tupou on the back of a cross-field bomb from Maloney, and the Five-eighth's sideline conversion brought the scoreline to 6–6. A few minutes later a contentious^{[citation needed]} penalty to the Roosters gave them another two points, and they took the lead into the halftime break, 8–6.^[1]

2nd half

In only the 43rd minute, Manly were in scoring position, with halfback Daly Cherry-Evans grubber-kicking for Lyon, however he was tackled without the ball by Roosters substitute Mitch Aubusson, leading the video referees to rule a penalty try. Lyon converted it to bring Manly-Warringah back to the lead at 12–8. A forced drop-out conceded by the Roosters put Manly into attacking position quickly and they capitalised, Matai scoring and Lyon again converting to push the score out to 18–8 with only 30 minutes remaining.^[1] Roosters back-rower Aiden Guerra next scored however, and a conversion brought the Roosters back into the game at 18–14, before a line-break and offload from Williams to Maloney opened Manly's defensive line. Maloney sprinted downfield and gave a pass to Minichello. The Roosters captain then put centre Shaun Kenny-Dowall in to score which, along with a conversion from Maloney, put the Minor Premiers back in the lead at 20–18 with 18 minutes to go. An error from the Roosters put Manly back into contention, but a knock on from winger David Williams and a lack of capitalisation on a Roosters mistake brought them back to the Manly end of the field following another line-break from the Roosters' Williams. A grubber kick from Maloney led to a freakish try to centre Michael Jennings, who grounded the ball only centimetres inside the dead ball line. A final conversion to Maloney took the score to 26–18, and even a short kick-off attempt from Manly couldn't crack the Roosters' defence in the last six minutes of play.^[1]

Post-match

Sydney Roosters captain Anthony Minichiello became the first fullback to captain his team to a Grand Final victory since Frank 'Skinny' McMillan in 1934.^[5] Manly halfback Daly Cherry-Evans was awarded the Clive Churchill Medal for best and fairest in the Grand Final, the first awarded to a player from a losing side since 1993, and only the third time this had happened, at the time. Jack Wighton, from the Canberra Raiders, later achieved this, coincidentally against the Roosters, in 2019.^[6] Roosters coach Trent Robinson became the first coach to win a premiership in their first year of coaching in the NRL since Ricky Stuart in 2002.^[7]

The premiership rings awarded to the members of the winning team were worth AU$6,000.^[8]
