AFL line betting and head-to-head are the two most-traded AFL markets in Australia, and both have their place in a serious AFL betting portfolio. The choice between them is not purely preference — each market has different vig, different price dispersion, and different ideal use cases. Knowing when to bet which is the difference between a sharp AFL operation and one that leaves value on the table.
This piece covers the structural differences between AFL line betting and AFL H2H, where each market offers value, the vig comparison across AU bookmakers, and the practical workflow for choosing between them on any given match.
The structural difference
AFL H2H markets ask a simple question: who wins the match? Prices reflect the implied probability of each team winning outright. A typical AFL H2H market at Sportsbet looks like:
- Collingwood to win: $1.65
- Essendon to win: $2.35
Implied probabilities of 60.6% and 42.6%, summing to 103.2% — vig of 3.2% on this particular market. Across AU bookmakers AFL H2H vig usually sits between 3% and 7% depending on the matchup and the book.
AFL line betting reframes the same match around margin. The bookmaker sets a handicap line and offers near-even-money prices on each side:
- Collingwood -20.5 at $1.91 (Collingwood must win by 21+ points)
- Essendon +20.5 at $1.91 (Essendon wins, draws, or loses by 20 or fewer)
Implied probabilities both 52.36%, summing to 104.72% — vig of 4.72%. Line bet vig at AU bookmakers is typically 4-5%, slightly tighter than H2H vig because the symmetric-around-even-money pricing structure is easier for bookmakers to manage.
Where line betting wins on value
Three structural advantages of AFL line betting for value-focused punters:
Tighter vig per bet. The 4-5% vig on line betting beats the 4-7% on H2H for most matches. Across many bets the lower vig compounds into meaningful value capture.
Granular margin views. If you think Collingwood will win but only by a moderate margin, line betting lets you express that view directly. H2H betting forces you into a binary "Collingwood wins" without distinguishing a 5-point win from a 50-point win. For matches where you have margin opinions rather than pure win-loss opinions, line betting is more efficient.
Better cross-bookmaker dispersion. AU bookmakers post different line numbers on the same match more often than they post meaningfully different H2H prices. Bet365 might have Collingwood -20.5 while TAB has -22.5 — that 2-point spread creates arbitrage and middle opportunities that don't exist as cleanly on H2H. The middle betting guide covers how to exploit this.
Where H2H wins on value
Three situations where H2H betting beats line betting:
Heavy underdog opinions. When you think a team is meaningfully more likely to win than the market implies, betting H2H captures the full upside. Line betting on the same view requires choosing whether they win narrowly or by a margin, which adds an extra opinion you may not have.
Public-money fades. AFL H2H markets show the strongest public-money biases — popular teams (Collingwood, Carlton, Richmond, Essendon) get over-shortened on H2H more than on line markets. The opportunity to fade the public is biggest on H2H. See the overrated teams piece for the framework.
Close finals games. AFL finals matches are typically priced tightly on line betting because models adjust appropriately for finals intensity. H2H markets sometimes lag in finals weeks, creating better value on the underdog H2H side than on the corresponding line.
Vig comparison across AU bookmakers
Tracked vig across the major AU bookmakers on AFL H2H and line betting:
- Bet365: H2H 3-5%, Line 3-4%. Sharpest book overall.
- Sportsbet: H2H 4-6%, Line 4-5%. Volume-focused.
- TAB: H2H 5-7%, Line 5-6%. Softest of the majors.
- Ladbrokes/Neds: H2H 4-6%, Line 4-5%. Sibling books.
- PointsBet: H2H 4-6%, Line 4-6%. Decent on both.
- Betfair Exchange: Effectively 0% margin in odds, 6.5% commission on net winnings. Tightest available pricing on liquid AFL markets.
For pure value-focused AFL betting, Bet365 line betting is typically the sharpest combination. For value betting on softer prices, TAB H2H markets sometimes have the largest deviation from market consensus — worth checking even though TAB's vig is wider.
Specific match patterns
Different match types favour different markets:
Heavy favourite vs heavy underdog (line ≥ -25): H2H is usually better value because heavy favourites get systematically overpriced on H2H markets and the H2H prices on the underdog side sometimes carry meaningful value. Line betting on these matches is generally efficient.
Even matchups (line within ±10 points): Line betting is generally better value because the symmetric pricing produces tighter vig and the cross-bookmaker line dispersion creates arbitrage and middle opportunities. H2H prices on close matches tend to be efficiently priced by bookmaker models.
Finals matches: Both markets are priced sharply but H2H sometimes carries value on the underdog side as bookmakers accommodate public money flow toward favourites in high-profile games.
Mid-season fixtures with public-team involvement: H2H is typically better value for fading the popular team, because line markets adjust the handicap rather than producing public-money bias on the prices.
Workflow: choosing between line and H2H
Practical decision tree for any AFL match:
- Calculate market consensus on H2H by de-vigging across AU bookmakers. Determine the consensus implied probability for each team winning.
- Calculate market consensus on line betting by checking the median line across AU bookmakers. Determine the consensus margin estimate.
- For your view, identify whether you have an opinion on win/loss (H2H view) or on margin (line view). Bet the market that matches your actual opinion.
- Compare best-available prices on both markets to consensus. Place the bet at the market with the largest deviation from consensus, scaled by relative vig.
For most AU bettors with mixed views, betting both markets selectively across the round is the right approach. H2H for the matches with clearest public-money biases. Line betting for closer matches and margin-specific opinions. The Krok Odds +EV Finder surfaces value across both markets in real time.
Sample size and CLV tracking
Track CLV separately by market type. Your average CLV on AFL H2H bets should be measured separately from your average CLV on AFL line bets, because the two markets behave differently. A bettor with strong H2H results and weak line results should concentrate further on H2H; the opposite indicates line betting is the higher-value lane.
Across a season, expect 50-100 H2H bets and 50-100 line bets if you bet both markets. Sample sizes that small make individual-market CLV somewhat noisy — but the directional signal is usually clear after 30-40 bets per market. See the CLV guide for the framework.
Frequently asked questions
Should beginners bet AFL H2H or line?
H2H is simpler and more intuitive for beginners. Once you're comfortable evaluating AFL match outcomes, expanding into line betting captures slightly better value through the lower vig. Most AU bettors start on H2H and gradually migrate toward line betting as their analysis sharpens.
What is the maximum stake for AFL line bets?
AFL line betting maximum stakes vary by bookmaker and customer. Sharp accounts get capped faster on line betting because the market is more efficiently priced — restrictions may hit at 100-200 line bets where H2H allows 200-400 bets at the same edge level. Stake limits on recreational accounts can be substantial ($5,000-$10,000+ per bet).
Is AFL line betting better than over/under totals?
Different markets entirely. Line betting is about the margin between teams. Totals betting is about the combined score. Both have similar vig levels. Choose based on whether your view is about margin or about scoring.
Can you parlay line and H2H bets?
AU bookmakers usually allow combining line and H2H markets on different matches into a multi. Combining the same match's line and H2H is usually prohibited or heavily correlation-adjusted because the outcomes are related. Multi vig compounds across legs — see the multis piece for the maths.
What's the best AFL line betting strategy?
For value-focused bettors: compare lines across AU bookmakers, fade public-money biases on heavily-traded matches, focus on the narrowest-vig books (Bet365), and track CLV religiously. The pattern that produces consistent profit on AFL line betting is roughly the same as on AFL H2H — find structural mispricings, bet against them systematically, ignore short-term variance.
