In 2026, Sportsbet, Bet365, Ladbrokes, and Palmerbet all offer best fluctuation (best fluc) products on Australian thoroughbred racing, paying the highest price the horse was quoted during the betting cycle. TAB operates a pari-mutuel tote model and does not offer traditional best fluc, though TAB provides best tote products on selected pools. Product conditions change frequently — verify on each operator's site before betting.
What is best fluc and how does it work?
Best fluctuation (best fluc) means the bookmaker pays you the highest fixed odds available on your selection at any point from the opening of betting through to the jump. If a horse opens at $8.00, drifts to $10.00 mid-session, then firms back to $6.00 at jump — best fluc pays you $10.00, regardless of which price you took at the time of betting.
Exact rules vary by operator: some apply best fluc from market open to jump regardless of bet timing; others apply it only from the moment of your placement to jump. Read each operator's product terms carefully before relying on best fluc, particularly in relation to scratchings, race abandonments, and exotic bets.

Best fluc vs best tote vs fixed odds — which is better?
Best fluc gives you the highest fixed price during the betting session. Best tote pays the better of the declared tote dividend or the bookmaker's fixed price (some operators pay the best of multiple tote pools — for example, the best of the NSW TAB, Vic TAB, and Queensland TAB dividends). Fixed odds gives you a locked-in price at bet placement, with no upside if the horse drifts after you bet.
There is no universally superior product. Best tote can outperform best fluc when pool money creates an overlay dividend — particularly on smaller meetings where heavy public money on a favourite inflates dividends on other runners. Best fluc outperforms best tote when a horse firms sharply after a barrier draw or late scratchings drive the field down. Experienced punters often assess which product is likely advantageous for each specific race.
Conditions and limitations to check before betting
Best fluc products typically apply to major metropolitan thoroughbred meetings; country, provincial, or harness meetings may be excluded. Verify each operator's applicable meeting list.
If a horse in a related bet (multi or exotic) scratches, best fluc may not apply to the affected legs — each operator has specific scratching rules. Each bookmaker also publishes a maximum win payout per race; best fluc applies only up to that cap. Bookmakers can modify or withdraw best fluc products at any time without notice.
- Meeting eligibility: confirm the specific meeting is covered by best fluc terms
- Scratchings: check how each operator handles best fluc when a runner in a related bet scratches
- Maximum payout: best fluc is capped at the operator's published maximum win limit
- Product terms: bookmakers can change or withdraw best fluc at any time — always verify before betting
Frequently asked questions
Does TAB offer best fluc for horse racing?
TAB does not offer traditional best fluc in the same way as corporate bookmakers. TAB's primary model is pari-mutuel tote betting, where the dividend is calculated from the pool after deductions. TAB does offer best tote products on selected races, paying the highest dividend from the relevant state tote pools. Check TAB's current product terms for the latest details.
Is best fluc always the best option for Australian horse racing punters?
Not always. Best fluc is most valuable when a horse drifts in price during the betting cycle after the market opens. If a horse is expected to firm (shorten significantly) before the jump, taking a fixed-odds price at jump may be more valuable. Comparing the opening price, current fixed odds, and tote fluctuations for each race before deciding is the most informed approach.
Are best fluc products regulated in Australia?
Yes. All products offered by ACMA-licensed bookmakers fall under the Interactive Gambling Act 2001 (Cth) and must comply with state and territory racing authority rules. Each operator's product terms must be publicly disclosed. ACMA licences operators; individual product terms are governed by the operator's own published rules under their relevant racing authority's jurisdiction.
