St Kilda vs Sydney Prediction & Tips: 2025 AFL Round 18

Tauru Takes Flight: Rookie Lighting Up a Losing Streak 

The Saints have put forward some gallant performances over the last few weeks to no avail as they are currently on a four game losing streak. They were impressive against Fremantle and Hawthorn in their last two games as coach Ross Lyon continues to blood young players. The emergence of rookie Alix Tauru has been a significant talking point at Moorabbin across his three games so far, with some already touting him as the next great hope for embattled St Kilda fans. The form of Nasiah Wanganeen-Milera continues to impress, and securing his signature will be far more important that securing wins in the last few months of the regular season.  

 

Flying Under the Radar: Swans Hit Their Stride

While the Swans still sit three games outside the top eight, their form has been without doubt the best of the bottom nine teams of late. With an injection of players back from injury, most notably Errol Gulden, they have won three of their last four games, and are coming off a fantastic win over the Dockers on the weekend. The midfield trio of Callum Mills, Errol Gulden and Chad Warner were impressive in the win over the Dockers, racking up 75 touches and kicking two goals between them.  

 

Swans’ Forward Line Takes a Hit as Amartey Joins Casualty Ward

The Saints have slowly been bringing injured players back into the line-up as well as blooding a good amount of youth, to the point where they are now nearly fully fit. Bookends Max King and Dougal Howard remain on the sidelines as does youngster Mattaes Phillipou, but outside of that, they will be near full strength this week. The same can’t be said for the Swans, who will now be without key forward Joel Amartey after he suffered a season ending groin injury against the Dockers. He joins Taylor Adams, Robbie Fox, Tom Papley, Dane Rampe and Logan McDonald on the injury list.  

 

Saints vs Swans? Here’s our St Kilda vs Sydney Tip 

Like the look of the unders here. The Saints defence has been really solid over the last few weeks, keeping the Dockers and Hawks to an average of just 87.5 points. The average total score in those two games has been just 159.0 points. The Swans are also seriously lacking avenues to goal at the moment with Papley, Amartey and McDonald all on the sidelines. That likely means Cal Wilkie will be able to do as he pleases in the backline. Think this is a low scoring game.

St Kilda vs Sydney Player Prop Bet

Our Best Player Prop: Isaac Heeney 2+ Goals

As we mentioned above, the Swans are lacking goal scoring options at the moment, and I think Dean Cox’s hand will be forced in moving Heeney into a permanent forward for this game. Especially with some midfield cavalry in Gulden and Mills back in the mix, Heeney is no longer required in the middle of the ground as much. Kicked four when the two teams met earlier this year.

Saints vs Swans Same Game Multi 

Max Hall 1+ Goal - The Saints forward/mid has unbelievably been the top rated player in the entire league from Rounds 14-17, showcasing a craft ability to win the ball and set up scoring chains. Has kicked five goals in the last three games and seems to have a knack for finding the big sticks.  

Nick Blakey 20+ Disposals  - Running half backs against St Kilda has been a trend that has been paying dividends over the last month, hitting on Bailey Dale (36), Josh Daicos (30), Jordan Clark (31) and Karl Amon (21) in the last four weeks. 

Nasiah Wanganeen-Milera 25+ Disposals - Value in Nas is dropping by the week but I still think there is enough meat on the bone at 25+ to justify the selection here, especially considering he is averaging 33.2 over his last five games.
