AFL Quarter-Time Leads: How Often Each Lead Size Wins and Covers
A quarter-time lead in the AFL wins more often than not, but how much more depends heavily on its size and on who was favoured before the bounce.
If a team leads at quarter-time in the AFL, how often does it go on to win, and cover the pre-game line, by lead size?

Quarter-time is the first honest look at an AFL match. The plan has met the ground, the wind has shown which end it favours, and the clearance battle has a shape. Across 4,605 matches from 2000 to 2024 with a leader at the first break, the side in front won 68.6%, drew 0.8% and lost 30.5%. That is a solid edge, but it is an average across very different situations.
This study sits alongside my Australian rules betting tips page and breaks that average apart. A 1-6 point lead converted only 54.0% of the time, close to a coin flip, while a 31+ point lead won 93.2%. In between, the climb is steady, and the pre-game favourite and underdog behave very differently with the same scoreboard.
Branch ABigger quarter-time leads convert at steadily higher rates
Each bar is a lead band, split into won, drew and lost at full-time. The small leads dominate the sample: 1,284 matches sat at 1-6 points and 1,109 at 7-12. Those two bands are where most of the uncertainty lives, at 54.0% and 63.0% wins.
The real step comes in the 19-24 point band, which won 81.6%, against 70.4% for 13-18 points. That is roughly the point where the trailing side needs more than one good passage of play to get back in, and a slippery afternoon makes that harder still.

| Won | Drew | Lost | |
|---|---|---|---|
| 1-6 pts (1,284) | 54.0% | 1.2% | 44.9% |
| 7-12 pts (1,109) | 63.0% | 0.7% | 36.2% |
| 13-18 pts (840) | 70.4% | 1.1% | 28.6% |
| 19-24 pts (624) | 81.6% | 0.8% | 17.6% |
| 25-30 pts (368) | 85.6% | 0.3% | 14.1% |
| 31+ pts (380) | 93.2% | 0.0% | 6.8% |
Even the biggest band is not safe. A 31+ point lead still lost 6.8% of the time, which in a sport with this much scoring momentum is a reminder that nothing is settled after the first break.
Branch BFavourites protect quarter-time leads far better than underdogs
This is the chart I find most useful. With a 1-12 point lead, a pre-game underdog went on to win only 39.6% of 644 matches, while a pre-game favourite won 72.8% of 779. The underdog in front is more likely to lose than win from there.
The gap narrows as the lead grows but never closes. With 25+ points in hand, underdogs won 70.9% and favourites 95.5%. The underdog samples are smaller, so their ranges are wider, especially in the biggest band of only 103 matches.

| Underdog led | Favourite led | 95% range | |
|---|---|---|---|
| QT lead 1-12 pts (644 underdog · 779 favourite leads) | 39.6% | 72.8% | ±3.8 |
| QT lead 13-24 pts (258 underdog · 562 favourite leads) | 58.1% | 84.9% | ±6 |
| QT lead 25+ pts (103 underdog · 335 favourite leads) | 70.9% | 95.5% | ±8.7 |
My reading: an early underdog lead often reflects a hot spell or a good wind quarter, not a shift in the underlying contest. The favourite's midfield usually wins the long argument at the stoppages.
Branch CLine cover rises with the lead but starts lower
Against the closing pre-game line from 2013 to 2023, quarter-time leaders covered 63.8% of 2,014 times. By band, 1-6 points covered 54.8%, rising through 58.9%, 61.4%, 71.0% and 77.8% to 90.7% for 31+ points.
Be clear about what this means: once the quarter-time score is known, that pre-game line can no longer be bet. These figures describe how leaders performed against the market's opening view, not a price you can still take. The line already expected the favourite to lead, so this rate mixes favourites and underdogs together.

| Share of QT leaders that beat their closing line, 2013-2023 | |
|---|---|
| 1-6 pts (571) | 54.8% |
| 7-12 pts (506) | 58.9% |
| 13-18 pts (350) | 61.4% |
| 19-24 pts (272) | 71.0% |
| 25-30 pts (153) | 77.8% |
| 31+ pts (162) | 90.7% |
The highlighted bands show where a lead clearly outran the pre-game handicap. For live line markets, it tells me the bookmaker's adjusted number has to move a long way before a big early lead looks generous.
Branch DFair in-play odds shorten sharply beyond 18 points
The table turns the dead-heat win rates into fair prices for the quarter-time leader. A 1-6 point lead is worth fair odds of 1.83, a 7-12 point lead 1.58 and a 13-18 point lead 1.41. From there the prices compress quickly: 1.22 for 19-24 points, 1.17 for 25-30 and 1.07 for 31+.
My main caveat belongs here. These are historical base rates, not a betting system, and live prices already react to the score. Scoring also fell over the period, so the same points lead was worth slightly more in recent seasons than at the start of the sample.
| QT lead | Matches | Won | Win rate (DH) | 95% range | Fair odds |
|---|---|---|---|---|---|
| 1-6 pts | 1,284 | 54.0% | 54.6% | ±2.7 | 1.83 |
| 7-12 pts | 1,109 | 63.0% | 63.4% | ±2.8 | 1.58 |
| 13-18 pts | 840 | 70.4% | 70.9% | ±3.1 | 1.41 |
| 19-24 pts | 624 | 81.6% | 82.0% | ±3.0 | 1.22 |
| 25-30 pts | 368 | 85.6% | 85.7% | ±3.6 | 1.17 |
| 31+ pts | 380 | 93.2% | 93.2% | ±2.5 | 1.07 |
I use these numbers as a benchmark, then adjust for what the first quarter actually showed: who won the clearances, where the wind sits, and whether the ground suits the leader's style.
If this happens…
An underdog ahead by 1-12 points at quarter-time won only 39.6% of the time. Do not let the scoreboard talk you into backing it in-play without a reason from the contest itself.
Leads of 19-24 points won 81.6% against 70.4% for 13-18 points. Check whether a live price has moved to reflect that step, with fair odds near 1.22.
Use the fair odds as a reference, such as 1.83 for a 1-6 point lead, and only act when your read of the game justifies a gap. A price shorter than fair with no supporting evidence is not value.
