AFL quarter betting is betting on part of a match: one quarter's result, line or total, a half time result, or a half time full time double. A quarter market counts only the points scored in that quarter, while a half time market uses the score at the long break, so a team can win the second quarter and still trail at half time. They sit beside the match markets in AFL betting.
Each quarter is 20 minutes of playing time, with the clock stopped for stoppages (Law 10.1 of the Laws of Australian Football 2026). Over the 2022 to 2026 home-and-away seasons, 1,026 games, the AFL's results show the quarters averaging 42.5, 41.4, 43.2 and 42.8 points.
Which quarter a bet settles on
A market at a break (quarter time, half time or three-quarter time) adds up everything so far, so only at quarter time does it match a quarter's own score. In this illustrative game, not a real result, a goal counts 6 and a behind 1, so 4.3 is 4 x 6 + 3 = 27:
| Quarter | Team A | Team B | Points in the quarter | Score at the break |
|---|---|---|---|---|
| First | 4.3 (27) | 2.4 (16) | Team A by 11 | Quarter time: 27 to 16 |
| Second | 2.2 (14) | 4.5 (29) | Team B by 15 | Half time: 41 to 45 |
| Third | 3.6 (24) | 2.3 (15) | Team A by 9 | Three-quarter time: 65 to 60 |
| Fourth | 4.1 (25) | 3.4 (22) | Team A by 3 | Full time: 90 to 82 |
Five bets on that game:
| Bet | Scores that count | Result |
|---|---|---|
| Team A -6.5, first quarter line | 27 - 16 = 11 | Wins |
| Team A to win the second quarter | 14 against 29 | Loses |
| Team A to lead at half time | 41 against 45 | Loses |
| Over 42.5, fourth quarter total | 25 + 22 = 47 | Wins |
| Half time full time, Team B/Team A | Team B led at the break, Team A won | Wins |
Scaling quarter lines and totals from the match
Start with the centre. The four quarter margins add up to the final margin, so scaling evenly gives each quarter a quarter of the match line: an illustrative -24.5 becomes 24.5 / 4 = 6.125 points.
Quarter margins had a standard deviation of 17.2 points across all 4,104 quarters, against 40.6 for final margins, so a quarter carries about 42% of a match's spread (17.2 / 40.6), not 25%. A normal model with illustrative spreads, the 36 points used in AFL line betting for a match and 17 for a quarter, gives:
| Full match | First quarter | |
|---|---|---|
| Favourite's expected margin | 24.5 | 6.125 |
| Favourite wins | 74.8% | 63.0% |
| Scores level | 0.9% | 2.2% |
| Fair price for the favourite, before any tie rule | 1 / 0.748 = $1.34 | 1 / 0.630 = $1.59 |
Near the centre, one point of a quarter line is worth about 2.3 percentage points, twice the 1.1 of a match line point.
Then check the market. Against a centre of 6.125, an illustrative first quarter line of -4.5 at $1.90 covers 53.8% of the time on the model: 0.538 x 1.90 = 1.022, about 2c per $1 above break-even. At -6.5 it covers 49.1%, and 0.491 x 1.90 = 0.933. Treat a gap as a question: scaling assumes the favourite's edge is spread evenly over four quarters, and a bookmaker's different number may say it is not.
Totals scale by scoring: the fourth quarter took 25.2% of all points from 2022 to 2026, so an illustrative 172.5 match total gives it 172.5 x 0.252 = 43.5. Their spread does not shrink to a quarter either: a standard deviation of 13.2 points against 29.4 for match totals, about 45% (13.2 / 29.4).
Risk: Betting involves risk. The model is a simplification, a quarter is a short and noisy contest, and a bet above fair on paper still loses often. See responsible gambling for limits and support.
AFL half time betting and half time full time
Half time markets use the score at the long break, the first two quarters together; second half markets count the third and fourth quarters only. A half time line of Team A -12.5 needs Team A ahead by 13 or more at the break.
From 2022 to 2026 the team ahead at half time won 773 of the 1,011 games that were not level at the break, 76.5%: 56.9% with a lead of 1 to 6 points, and 98.6% with 37 or more. The team behind won 228, 22.6%, and the other 10 were drawn. These rates help price a bet before the game: online betting closes when it starts (Interactive Gambling Act 2001, s 8A(3) and s 10B).
AFL HT/FT: nine outcomes tied to the head to head
A half time full time (HT/FT) bet names the half time leader and the full time result, a draw included at either point: nine outcomes. The three ending in a Team A win add up to Team A's head to head chance, which ties the two markets together. With Team A an illustrative 68% chance:
| HT/FT | Model chance | Illustrative price |
|---|---|---|
| Team A/Team A | 54.0% | $1.70 |
| Draw/Team A | 0.9% | $41.00 |
| Team B/Team A | 13.1% | $6.00 |
| Team A/Draw | 0.6% | $67.00 |
| Draw/Draw | 0.1% | $151.00 |
| Team B/Draw | 0.3% | $101.00 |
| Team A/Team B | 8.4% | $9.00 |
| Draw/Team B | 0.5% | $67.00 |
| Team B/Team B | 22.1% | $3.90 |
Team A's winning rows add to 54.0% + 0.9% + 13.1% = 68.0%. The nine prices make a 119.3% book (the sum of 1 / price), against 104.8% for a head to head at $1.40 and $3.00.
At these chances Team A/Team A at $1.70 returns 0.540 x 1.70 = 92c per $1. Team A's head to head at $1.40 returns 0.68 x 1.40 = 95c, plus about 1c from the 1% draw under a dead heat or void rule, about 96c in all. In these illustrative books, HT/FT is a narrower bet at a bigger margin, not a better price on the favourite.
Where only the four team combinations are listed, a level break settles under your bookmaker's draw rule; half time full time in soccer covers a sport where draws are common.
Highest scoring quarter: what the results show
A highest scoring quarter market pays on the quarter with the most combined points. Count a tie as a dead heat rule would, splitting the win between the tied quarters. The third quarter's 21 ties were all two-way, so its share is (277 + 21 / 2) / 1,026 = 28.0%. Against illustrative prices that make the last quarter favourite:
| Quarter | Topped outright | Tied for top | Share, ties split | Fair price | Illustrative price | Pays per $1 at that share |
|---|---|---|---|---|---|---|
| First | 237 | 14, one three-way | 23.8% | $4.21 | $3.75 | 89c |
| Second | 225 | 17, one three-way | 22.7% | $4.40 | $4.00 | 91c |
| Third | 277 | 21 | 28.0% | $3.57 | $3.50 | 98c |
| Fourth | 251 | 21, one three-way | 25.5% | $3.93 | $3.10 | 79c |
Fair price = 1,026 / (outright + two-way ties / 2 + three-way ties / 3). The four prices make a 112.5% book, and the favourite is the worst value at the base rate. Past results are no guarantee of future results.
The last quarter is not high scoring by default: in games within 12 points at three-quarter time it averaged 40.9 points, against 41.1 for the earlier quarters. It outscored them mainly in games already 37 or more points apart (46.3 against 44.4).
Ties for top came up in 36 games, 3.5%. If your terms apply a dead heat, $20 on the third quarter at $3.50 tied with the fourth returns $20 x 3.50 / 2 = $35, while a market that lists the tie pays only the tie. Dead heat rules explains the split.
Wind, ends and the coin toss
Under Law 12.1 of the Laws of Australian Football 2026, the away captain calls the toss, the winner picks the end to attack in the first quarter, and the teams change ends after every quarter. The toss is two minutes before the start (Regulation 10.5 of the 2026 AFL Regulations), only minutes before online betting on the game closes.
So a team attacks the same end in the first and third quarters. If a breeze favours one end, a quarter line or total scaled evenly from the match ignores it. The AFL's match records type only 9 of the 1,026 games as WINDY, too few to measure, so treat wind as a judgement from the forecast, one the bookmakers make too.
Level scores at a quarter or at half time
From 2022 to 2026, 3.0% of first quarters were level, 2.1% of second, 2.3% of third and 1.9% of fourth: 97 of all 4,104 quarters (2.4%), against 1.5% of games level at half time and 1.0% at full time. Your bookmaker's terms set the rule for each market, so check them before you bet a quarter or half time result.
Example: Illustrative price only. You have $25 on Team A to win the first quarter at $1.62 and the quarter is level. A dead heat returns $25 x 1.62 / 2 = $20.25, a $4.75 loss; a void returns your $25; and in a market that listed the tie, your bet loses.
A half-point quarter line cannot land level with the margin; a whole-number one can, about 2% to 3% of the time near the centre, and the terms decide how it settles. AFL draw rules covers the whole-game version, finals included.
Mistakes that cost money on quarter bets
| Mistake | The cost, using the figures above |
|---|---|
| Reading a first quarter win as a half time lead | Team A won the first quarter by 11 and still lost its half time bet, 41 to 45 |
| Pricing a quarter head to head off the match price | 74.8% for the match but 63.0% for the first quarter: fair $1.34 against $1.59 |
| Assuming the last quarter scores most | At $3.10 the fourth quarter returns 79c per $1 at its base rate |
Skip quarter markets when your only view is who wins: the head to head and line carry that view directly. Quarter bets fit a view on how a game unfolds: a breeze, a slow start or a late blowout.
