St Kilda vs. Sydney Predictions - AFL Round 21 2026Ended

We have St Kilda vs. Sydney predictions for AFL Round 21 on Saturday, August 1 at 1:05pm at Marvel Stadium.

Kicking off Super Saturday is a blockbuster between the Saints and Swans, which has a big impact on the title race.

Best Bet

St Kilda +13.5 @ $1.90

Bet Now

Consistency has been tough to come by for St Kilda, but their win over North Melbourne last week was good, and they could find their way into the top eight with a win over Sydney.

The Swans also got back to their best with a win over GWS last week, but they were made to look good. GWS’s defence was poor in allowing Sydney to score 139 points, and St Kilda’s defence is usually much stronger.

We expect Sydney to struggle on the road, as they did when losing away from home against Brisbane and Fremantle. Those were tough games, but St Kilda is a solid team on its day, and getting a +13.5 start is significant for the home team.

The more desperate team is St Kilda, which sits in 9th on the ladder, and they need to end the season well to make the finals. That’s enough for us to include them in AFL picks as the underdog.

Same Game Multi

St Kilda +13.5, Jack Higgins 2+ Goals, Nasiah Wanganeen-Milera 2+ Goal, Total Points Over 182.5 @ $9.00

Bet Now

Jack Higgins has been kicking well for St Kilda, having kicked three doubles in his last four games. They need him to play a good game to beat Sydney, and we’re backing him in. The $1.76 odds for 2+ goals are worth including in picks.

Punters get better odds for Nasiah Wanganeen-Milera 2+ goals at $2.50. He had been struggling to kick goals before last week, but he fired a four-goal effort against North Melbourne, and he could keep that form going.

Bookmakers have set a big line at 182.5 points, but we’re backing the over. Sydney won the previous encounter 104-102 in June, which is the best form guide for Saturday’s clash.

Best Value Bet

St Kilda 1-39 @ $3.20

Bet Now

Our AFL predictions have St Kilda winning outright, but we can’t see them winning by 40+ points.

There is value in betting the 1-39 margin instead of backing St Kilda to win outright at $2.67, so punters should climb into the margin bet.

The $3.20 odds could firm throughout the week, so take the value available.
