Port Adelaide vs. GWS Predictions - AFL Round 21 2026Ended

We have Port Adelaide vs. GWS predictions for AFL Round 21 on Saturday, August 1 at 6:35pm at the Adelaide Oval.

One of the closest games of the week is the Power vs. GIANTS, where AFL odds have Port Adelaide at $1.83 to win, but GWS should come to play.

Best Bet

GWS @ $2.01

Bet Now

We’re not sure what to make of GWS after losing to Essendon and Sydney, but we’re looking at their form from a couple of weeks ago when beating Fremantle and Geelong in consecutive weeks.

Losing to Essendon was a real shock, and it dented their finals chances in a big way. They weren’t able to recover from that loss last week against Sydney, but playing Port Adelaide is typically a recipe for success.

Port Adelaide is struggling to show its best after three straight losses. The Power lost to St Kilda, Fremantle, and Brisbane, so they were tough games, but they were only competitive when losing to St Kilda 87-73. They’re not playing well enough to beat GWS, and we can’t justify the $1.83 odds.

If GWS brings its best, it could blow Port off the field, so take the underdog odds with bookmakers.

Same Game Multi

GWS H2H, Aaron Cadman 2+ Goals, Callum Brown 2+ Goals, Total Points Under 168.5 @ $14.00

Bet Now

Aaron Cadman is a key player for GWS, and they need him to produce more goals. He started the year well, but he has only two goals in his last three games. GWS needs him to deliver, and we’re backing him to kick 2+ games.

Callum Brown is another player looking to post his first 2+ goal game in the last three games. He looked good when kicking three against Geelong, and the $2.65 odds provide a big boost to AFL SGM picks this week.

We’re also including under 168.5 points, as we have Port struggling to produce a big total.

Best Value Bet

GWS 40+ @ $6.75

Bet Now

The odds are good enough to include GWS 40+ in AFL picks as a value bet.

We believe GWS, at their best, are much better than Port Adelaide, and their record suggests as much. They scored wins over Fremantle and Geelong, so if they can beat them, they can win this game by a big margin.

We’re happy to take the risk considering the big odds.
