Key facts
- Under the Australian Harness Racing Rules, races are run from mobile starts unless the controlling body or chief steward approves otherwise; the alternative is a standing start.
- A horse in a mobile start is a starter once it faces the mobile barrier and the barrier starts to move; stewards can declare a non-starter if a horse was denied a fair start.
- A horse that causes two false starts through its own intractability is withdrawn and declared a late scratching.
- Pacers and trotters race in separate events: HRV's 2026 summer carnival ran a Pacing Cup and a Trotters Cup at each of five country tracks.
- Racing Queensland is hosting the Inter Dominion at Albion Park from 2025 to 2027; the 2025 pacing final was worth $1 million.
Harness racing betting, the short version
Harness racing betting is betting on the trots, where horses race behind a driver as pacers or trotters. You use the same bet types as thoroughbred racing (win, place, quinella, exacta, trifecta, first four and multi-race bets), with the TAB or a licensed Australian bookmaker, at fixed odds or on the tote. What changes is the start. The Australian Harness Racing Rules set out how races start, when a horse counts as a starter and when it does not, and those rules decide whether your bet runs or is refunded. For the bet types themselves, see our guide on how to bet on horses.
Pacers and trotters
Pacing and trotting are two different gaits, and they race separately in feature events. Harness Racing Victoria's 2026 summer carnival showed the split:
| Date (2026) | Track | Pacing feature | Trotting feature |
|---|---|---|---|
| 10 January | Bendigo | Group 2 Pacing Cup | (Group 1 Maori Mile on the same night) |
| 17 January | Shepparton | Group 3 Pacing Cup | Group 3 Trotters Cup |
| 24 January | Ballarat | Group 2 Pacing Cup | Group 1 Trotters Cup |
| 31 January | Cranbourne | Group 1 Pacing Cup | Group 1 Trotters Cup |
| 7 February | Kilmore | Group 1 Pacing Cup | Group 1 Trotters Cup |
| 14 February | Melton | A G Hunter Cup, $250,000 | Great Southern Star, $250,000 |
When you read form, compare a trotter with trotters and a pacer with pacers.
Mobile starts and standing starts
The start is where trots betting differs most from the gallops. Under the Australian Harness Racing Rules:
| Rule | What it says | Why it matters to your bet |
|---|---|---|
| Rule 142 | Races are run from mobile starts unless the controlling body or chairman of stewards approves otherwise | Most races start behind a moving gate |
| Rule 128 | Races start from a mobile barrier or a standing start barrier | Standing starts are the other method |
| Rule 130 | Horses are drawn up by handicap as far as practicable; horses on the same mark are drawn in barrier positions | A horse's mark and draw shape its chance |
| Rule 128(3) | In a mobile start, a horse has taken part once it faces the barrier and the barrier starts to move | From then, it is a starter for betting |
| Rule 128(4) | In a standing start, a horse has taken part once it has faced the barrier as directed | The same, for standing starts |
| Rule 141(1)(b) | Stewards may declare a horse a non-starter if it was denied a fair start | A non-starter is treated like a scratching |
| Rule 141(4) | A horse causing two false starts through its own intractability is withdrawn and declared a late scratching | Bets on it are refunded, others may face a deduction |
In a handicap race, horses start from different marks, so read a horse's mark as part of its price.
Scratchings, non-starters and refunds
A late scratching in harness racing can come from the start itself, not just from a withdrawal before the race. On the TAB, win and place bets on a scratched runner are refunded. At fixed odds, bets on the other runners stand but can face a deduction when a runner is withdrawn after you bet, under the bookmaker's deductions table.
Place dividends follow field size on the TAB: 8 or more starters pay three places, 5 to 7 pay two, and with 4 or fewer, place bets are refunded.
The result that counts
Under the TAB's Victorian rules, the official result for harness racing is the one declared immediately following the All Clear. That is what your bet is paid on.
Dead heats on the trots
When two horses cannot be separated on the line, the dead heat rules decide what you collect. On the TAB tote, a dead heat for first splits the win pool between the dead heaters, and a dead heat for third pays four place dividends instead of three. At fixed odds, the dead heat rule divides your payout: $10 at $6.00 on a horse that dead heats for first returns $30, not $60. Our guide to dead heat rules covers every case.
Exotics: boxing and flexi on the trots
Exotics pay more and cost more, and boxing multiplies the cost. TAB box costs at $1 units:
| Runners boxed | Exacta | Trifecta |
|---|---|---|
| 3 | $6 | $6 |
| 4 | $12 | $24 |
Flexi lets you bet a fraction of the full unit. $6 on a four-runner trifecta box that costs $24 at $1 units is a flexi bet of 25%, and you are paid 25% of the dividend. The boxed trifecta calculator works out any box.
Tote commissions are higher on exotics: 14.50% on win and 14.25% on place, but 20% on exactas, 21.50% on trifectas and 23% on first fours. Compare tote and fixed prices with our tote vs fixed odds guide.
Driver challenge betting
The TAB's Victorian rules describe a Jockey, Driver and Trainer Challenge: a bet on the driver with the most points across a meeting or carnival.
| Placing | Points | Dead heat for that placing |
|---|---|---|
| 1st | 3 | 2.5 each |
| 2nd | 2 | 1.5 each |
| 3rd | 1 | 0.5 each |
A driver with two wins, a second and three thirds scores 6 + 2 + 3 = 11 points. Points go only to the driver who actually drives, there are no refunds if a driver is replaced, and a tie on points at the end divides the payout by the number of drivers tied.
The Inter Dominion
Racing Queensland calls the Inter Dominion Australasia's premier harness racing event. It announced in October 2024 that it would host the series at Albion Park from 2025 to 2027. In 2025 the heats were on 5 and 12 July and the finals on 19 July, with a $1 million pacing final and a $400,000 trotting final.
Series races are settled one by one, but the format affects the field in each final. In Victoria's 2022 series, for example, heat points ran from 16 for a win down to 1 for 12th, and the leading 12 in each of the pacing and trotting divisions made the Group 1 finals.
Trots betting and the law
Harness racing bets are legal with the TAB or a bookmaker licensed in an Australian state or territory. Since 11 June 2024, licensed online and phone wagering providers cannot take credit cards, credit-related products or digital currencies. ACMA lists betting services not licensed in Australia as illegal to offer online.
Pundit tip: in a standing start, a horse that breaks or begins slowly can lose its chance in the first few strides. Price that risk in before you bet, because a bad start that still counts as a start will not get you a refund.
Greyhound racing uses the same tote and place rules with an eight-dog field; see our greyhound betting guide. For prices from scratch, read how to read odds, and for every bet type our bet types guide.
Frequently asked questions
What is the difference between a mobile start and a standing start?
In a mobile start, horses line up behind a mobile barrier that moves off with the field. In a standing start, horses face a standing start barrier as directed by the starter. The Australian Harness Racing Rules make mobile starts the default unless another method is approved.
Are pacers and trotters in the same race?
Not in feature events. They race in separate pacing and trotting races and series, such as the separate Pacing Cups and Trotters Cups on Harness Racing Victoria's summer carnival, and separate pacing and trotting finals at the Inter Dominion.
What happens to my bet if a harness horse does not start properly?
Stewards can declare a horse a non-starter if it was denied a fair start, or a late scratching if it caused two false starts through its own intractability. Win and place bets on a scratched runner are refunded on the TAB.
When is a harness race result official for betting?
Under the TAB's Victorian rules, the official result for harness and greyhound racing is the one immediately following the All Clear. Bets are settled on that result.
What is a driver challenge bet?
A bet on the driver who scores the most points across a meeting or carnival. The TAB's Victorian rules give 3 points for a win, 2 for second and 1 for third, and split points for dead heats.
