The Dolphins return to Suncorp one win away from their first NRL Grand Final after overcoming a 16-8 deficit to beat the Warriors 26-16. They have now won eight straight overall and eight straight at Suncorp, including a 48-10 demolition of the Roosters earlier this season.
Sydney snapped a four-game losing streak with a 46-10 win over Cronulla last weekend and receive a huge boost with Sam Walker returning just 24 days after syndesmosis surgery. His combination with Daly Cherry-Evans certainly makes the Roosters more dangerous, but they still need to overturn two convincing losses to the Dolphins this season.
Dolphins Over 22.5 points is the second selection. Redcliffe have averaged 31.6 points at Suncorp this season and have scored at least 23 points in 10 of their 12 matches at the venue. They won all 10 of those games.
There are options everywhere in the Dolphins backline for the tryscorer market, but Selwyn Cobbo has the best value considering his try scoring run and the fact he scored a double against the Chooks this season. Cobbo has scored in six consecutive matches with eight tries during that run and has crossed 16 times across his last 12 appearances.
Jeremy Marshall-King is the value alternative after scoring in both games against the Roosters this season.
Key Stats & Trends

Head to Head
The Dolphins have taken control of this matchup in 2026, winning both meetings with the Roosters by double figures.
Redcliffe smashed Sydney 48-10 at Suncorp Stadium in Round 15 before travelling to Allianz Stadium as underdogs in Round 26 and winning 26-12.
The Roosters still lead the short all-time rivalry 4-3, but the Dolphins have won three of the four meetings played at Suncorp.
Dolphins Form Analysis
The Dolphins enter the preliminary final on an eight-game winning streak and have won 16 of their last 18 overall. Their qualifying-final victory over the Warriors demonstrated another side of this team, with Redcliffe trailing for most of the match before scoring 18 unanswered points to win 26-16.
Hamiso Tabuai-Fidow and Herbie Farnworth were instrumental in the comeback and, alongside Cobbo, Jamayne Isaako and Jack Bostock, give the Dolphins attacking threats across the entire backline.
Suncorp has also become a significant advantage. The Dolphins have won their last eight at the venue, with their only two defeats there this season coming back in March.
Tom Flegler returns after clearing the concussion protocols following his early HIA against the Warriors, while the experienced Felise Kaufusi has also been recalled.
Sydney Roosters Form Analysis
The Roosters finally broke their four-game losing streak in emphatic fashion, beating Cronulla 46-10 to keep their season alive.
Daly Cherry-Evans produced one of his best performances of the season with a try and three assists, while James Tedesco again led from the back and Mark Nawaqanitawase crossed twice.
The return of Walker now gives Sydney another attacking dimension. Cherry-Evans moves to five-eighth and the Roosters suddenly have two elite kicking and playmaking options in the halves.
How Walker handles his rapid return from surgery remains the question. The Roosters have already struggled twice against this Dolphins side in 2026, scoring just 22 combined points across the two defeats.
