Australia's National Basketball League offers a distinctive betting proposition compared to the NBA. With only 10 teams and a season running from September through March (plus finals into April), the NBL is a compact league where roster depth is thinner and individual player impact is magnified. Scoring totals tend to sit lower than NBA games — typically in the 150–180 combined point range — and the pace of play is generally slower, which can create tighter, more volatile contests. The smaller market size means bookmakers dedicate fewer resources to shaping NBL lines, which can create genuine edge opportunities for bettors who follow the league closely. Market depth is narrower than major North American leagues; while spreads, totals, and moneylines are widely available, player prop markets and alternative lines are more limited and often carry wider margins.
Vig on NBL markets is typically wider than what you'll find on NBA or major European basketball leagues. Sportsbooks face lower betting volume and less liquidity on NBL games, which incentivizes them to build in larger margins as protection against sharp action. Moneyline vig on NBL matchups can run anywhere from 5% to 8% at less competitive books, while spreads often carry juice beyond the standard -110/-110 seen in high-volume markets. This makes comparing odds across sportsbooks particularly valuable — the variance between the sharpest and softest lines on a given NBL game can be significant.
Seasonal patterns matter. Early-season lines tend to be softer as bookmakers calibrate to roster changes, import player arrivals, and coaching adjustments — this is often where the widest vig and the most mispriced lines appear. As the season progresses and data accumulates, lines tighten and margins narrow, particularly during finals when betting volume spikes. Home-court advantage plays a meaningful role in NBL odds; teams like Perth and Melbourne historically perform well at home, and travel fatigue across Australia's vast distances is a genuine factor. Injury news moves lines sharply given the reliance on one or two key imports per roster, making lineup monitoring essential for anyone betting this league seriously.

What is vig (vigorish) in sports betting?
Vig — short for vigorish, also called juice or overround — is the margin a sportsbook builds into its odds. It's the difference between the true probability of an outcome and what the odds imply. Lower vig means you keep more of your winnings on every bet. For example, a standard -110/-110 line has about 4.76% vig.
How often is this data updated?
We pull fresh odds from The Odds API every hour, on the hour (UTC). Each snapshot captures the latest lines from every sportsbook that has posted odds. The timestamp at the top of the page shows the most recent refresh.
How is the vig grade calculated?
Each sportsbook is graded on average vig: A+ (under 2%) is exchange-level pricing, A (2–3%) very competitive, B+ (3–4%) above average, B (4–5%) the industry standard, C+ (5–6%) slightly below average, C (6–7%) below average, D (7–8%) high vig, D− (8–10%) very high, F (10%+) predatory.
Why does lower vig matter for bettors?
Lower vig directly impacts your long-term returns. A bettor placing $1,000 per week at a book with 4% vig loses roughly $40/week to the house edge. At 2% vig, that drops to $20/week — a $1,040 difference over a year. For serious bettors, shopping for lower vig is one of the most reliable ways to improve profitability.
What sportsbooks do you track?
We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnything). Data comes from The Odds API, which aggregates real-time lines from licensed sources.
How We Calculate These Numbers
- Data Source
- All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
- Update Frequency
- We pull a fresh snapshot of every tracked market every hour, on the hour (UTC). Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
- Vig Calculation
- Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
- Per-Market Breakdown
- We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
- Grading Scale
- Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exchange-level pricing. A (2–3%) is very competitive. B+ (3–4%) is above average. B (4–5%) is the industry standard — a -110/-110 line is 4.76%. C+ (5–6%) is slightly below average. C (6–7%) is below average. D (7–8%) is high vig. D− (8–10%) is very high vig. F (10%+) is predatory pricing. See the full Vig Index Methodology for formulas, worked examples, and known limitations.
- Trend Tracking
- We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
