AFL Betting Tips 2025: Round 20 Best Bets And Betting Trends

There will be plenty of jostling for positions in the final rounds of the home and away season with just one win separating third from seventh place at the start of this weekend.

Further down the standings, the Western Bulldogs and the Sydney Swans are almost on their last legs, with the latter one game behind the Bulldogs but in much more convincing form. 

We’re expecting the Swans to play out a tight contest with their crosstown rivals in western Sydney on Friday night and have taken a particular interest in that game as well as two others, where our research points to some potential value in totals markets. 

Here are our three best picks from the many markets offered by the best Australian betting apps as well as the best odds available for three popular player picks.

AFL Round 20 Predictions:

• Giants Vs Swans: Either Team To Win By Under 24.5 Points - 1.82 With Betr
• Tigers Vs Magpies: Over 154.5 Points - 1.90 With PickleBet
• Saints Vs Demons: Over 168.5 Points - 1.90 With PlayUp

Sydney Vs GWS Giants, Friday 7:40pm AEST

Sydney will be hoping that the 31st Battle of the Bridge is their sixth consecutive win over the GWS Giants, not least because other results going their way could see them end the weekend just one victory outside the eight. 

It’s a tough task to claw back the deficit but five wins from their last six games have kept them in the hunt, even though it has been a soft run with four of those wins coming against current non-finalists.

With three top-eight opponents to come, they’ll need to improve upon their 3-6 record as outsiders this year, whilst their opponents are far from assured from victory having won only 60% of games as favourites (league average: 74%).

AFL betting sites are forecasting this to be one of the closest games of the round, and we’re in agreement with the single-digit line that has been set.

That’s why we’ll hopefully be making some money by sitting on the fence and taking the odds of 1.82 for a final margin of under 24.5 points. 

Toby Greene has returned to consistent goalkicking form in recent weeks, recording 2+ goals in his last four appearances, and should be determined to end a run of four straight head-to-heads with 0-1 goals. 

You can get around Evens on some bookmakers such as Unibet for the feat.

Best Bet: Giants Vs Swans: Either Team To Win By Under 24.5 Points - 1.82 With Betr

Player Prop: Toby Greene 2+ Goals - 2.04 With Unibet

Richmond Vs Collingwood, Sunday 2:10pm AEST

There are some very low totals expected by betting sites this weekend such as only 148.5 points in the Showdown and just 154.5 at the MCG between Richmond and Collingwood.

That comes as no surprise when considering that these two sides are in the bottom three of the competition when it comes to total points per game.

However, even this total is abnormally low when compared with those - and the rain expected on Sunday is not likely to be a significant hindrance. 

Games involving Collingwood are averaging 160 points this year and Richmond 159, whilst their combined points for and points against in 2025 stands at 156 and 163 respectively.

Five of the last six full-length games between these sides (so excluding 2020) cleared 155 total points, the most recent of which saw Collingwood triumph 93-67. The mark set for this game could just be a little too short. 

We’ve dived into the custom player disposals markets offered by Ladbrokes to take a haul of 22+ possessions for Richmond’s Sam Banks.

Banks has cleared 22+ in six of his last nine games, but got beyond the traditional 25+ only four times. It’s about playing the percentages. 

Best Bet: Tigers Vs Magpies: Over 154.5 Points - 1.90 With PickleBet

Player Prop: Sam Banks 22+ Disposals - 1.73 With Ladbrokes

St Kilda Vs Melbourne, Sunday 3:15pm AEST

Another total points target we’ll be attacking also comes on Sunday afternoon, whentwo of the worst form teams of the competition will be looking for some much-needed relief. 

The only victory St Kilda tasted from their last 10 games came against their next opponents Melbourne on the first day of June (91-63), with most of their losses coming against top-eight clubs albeit in addition to a pair of humiliating defeats to Carlton and West Coast. 

Melbourne’s six losses from their last seven games began with the previous head-to-head and their only joy came against lowly North Melbourne. 

These two clubs possess two of the six worst defences in the competition and that’s in part why St Kilda are fourth in the competition for total points per game (79.9 for and 93.7 against). 

Revved up by a pair of under-pressure coaches, both clubs are expected to attack this rare opportunity for victory in aggressive fashion and record what would be a fifth consecutive Saints game at Marvel Stadium to finish over the main total points handicap.

At least two of the goals should come from Melbourne forward Bayley Fritsch.

Fritsch kicked 2-3 goals in nine of his last 13 games and presents at almost Evens on AFL betting apps. 

Best Bet: Saints Vs Demons: Over 168.5 Points - 1.90 With PlayUp

Player Prop: Bailey Fritsch 2+ Goals - 1.96 With Betr
