Australian tote betting is about to undergo one of its biggest structural changes in decades, with TAB One Pool preparing to combine the country's three major pari-mutuel wagering pools into a single national system.
Tabcorp began live testing of the technology on Thursday, with thoroughbred racing at Warwick, harness racing at Tamworth and greyhound racing at Mount Gambier included in the opening trials.
A full day of domestic testing is scheduled for Monday, 28th September. If those tests are successful, Tabcorp is provisionally targeting the weekend of 3rd October for the formal launch of One Pool, although a final launch date remains subject to the results of testing.
So what exactly is TAB One Pool, and what will it mean for Australian racing punters?
What Is TAB One Pool?
One Pool is Tabcorp's new national totalisator wagering system. At present, Australian tote betting is divided across three major pools:
| Current Tote |
Main Jurisdictions |
| NSW TAB |
New South Wales |
| SuperTAB |
Victoria, Western Australia and ACT |
| UniTAB |
Queensland, South Australia, Tasmania and Northern Territory |
One Pool is designed to combine wagering currently directed into those systems into one larger national pool. That means customers participating through the different jurisdictions can ultimately be betting into the same underlying pool rather than having their tote bets calculated through separate state-based systems.
How Does Tote Betting Work?
One Pool is easier to understand if you first understand how tote betting differs from fixed odds.
With fixed odds, the bookmaker displays a price and, once the wager is accepted, that price generally determines the return if the selection wins, subject to the applicable betting rules. The tote works differently. Money wagered on the race goes into a pool. After deductions, the remaining pool is divided among winning tickets.
The final dividend therefore depends on factors including how much money is in the pool and how that money has been distributed among the runners. That's why tote prices can continue moving before the pool closes.
Why Is TAB Combining the Tote Pools?
The central argument is liquidity.
Instead of money being fragmented across several Australian pools, One Pool brings it together. Tabcorp CEO Gillon McLachlan has said the merged pool is intended to increase liquidity and create greater price stability.
That doesn't mean One Pool will automatically pay a better dividend on every winning bet. What a larger pool should do is make prices less sensitive to individual bets, particularly in markets where liquidity is relatively low. A bet that represents a substantial percentage of a smaller pool can cause a significant change to the projected dividend. The same wager represents a smaller percentage of a larger combined pool.
Will Everyone Get the Same Tote Dividend?
That's one of the fundamental changes.
Under the unified system, customers participating through the combined pools on the same race are intended to receive the same winning One Pool dividend, rather than different dividends being calculated across the existing separate pools.
That should also make TAB's tote product easier to understand. Instead of presenting multiple Australian tote prices, the longer-term objective is to have a single national tote dividend.
What Will Happen to NSW TAB, SuperTAB and UniTAB?
The wagering currently directed through those separate pools will be combined under the One Pool structure.
The jurisdictions themselves aren't disappearing. Rather, it is the underlying liquidity and dividend calculation that is being consolidated.
NSW TAB, SuperTAB and UniTAB collectively cover every Australian state and mainland territory, giving One Pool a genuinely national footprint.
What Will One Pool Look Like on Sky Racing?
The launch will also change the way tote prices are displayed on Sky Racing.
Once the full One Pool system is operating, Tabcorp plans to introduce refreshed Sky Racing graphics showing TAB Fixed Odds alongside the One Pool price.
That potentially creates a considerably simpler presentation than displaying several different tote pools. The September testing phase isn't using the final One Pool branding and broadcast package, so viewers shouldn't expect the finished presentation until the formal rollout.
Could One Pool Mean Bigger Jackpots?
Potentially. Tabcorp has identified larger jackpots and new tote products as longer-term opportunities created by a larger national liquidity pool.
Chief Wagering Officer Michael Fitzsimons has specifically pointed to deeper pools, larger jackpots and new products as opportunities created by the national system. The important distinction is that these are future opportunities, not necessarily products that will all appear on the first day One Pool launches. Getting the national pool infrastructure operating is the first step.
Will One Pool Include International Racing?
One Pool is initially focused on consolidating Australia's domestic tote structure.
However, Tabcorp has also identified greater international co-mingling as a potential longer-term opportunity. Combining Australian liquidity into one pool could make integration with large overseas pools more practical. The technology underpinning One Pool has already been used in connection with Tabcorp's international racing pools.
BetMakers Technology Behind One Pool
One Pool has been developed using technology co-engineered by Tabcorp's wagering division and Australian racing technology company BetMakers.
That relationship is particularly significant because Tabcorp has also agreed to acquire BetMakers.
The One Pool project therefore forms part of a broader overhaul of Tabcorp's wagering technology rather than being a simple rebranding exercise.
Why Is Tabcorp Changing the Tote?
The tote has been losing ground to fixed-odds wagering. Recent industry reporting indicates Tabcorp's tote pools have been contracting by approximately 5–6% annually, while the proportion of the company's wagering business coming from tote betting has fallen considerably from earlier years.
One Pool is designed to make the product more competitive by addressing one of the inherent weaknesses of fragmented pools: liquidity. A larger national pool should provide greater stability while also giving Tabcorp more scale to develop new products around the tote. Whether that translates into renewed customer interest will become clearer after launch.

What Does One Pool Mean for Racing Punters?
The most obvious change should be simplicity.
Instead of several Australian tote pools producing different dividends, One Pool is designed to create one national liquidity pool and one corresponding dividend.
The deeper combined pool should also make projected dividends less volatile. But it's important not to confuse greater price stability with guaranteed better prices.
A tote dividend is ultimately determined by how money is distributed through the pool. Combining pools changes the size and composition of that pool; it doesn't guarantee that every winning selection will return more.
One Pool represents a significant change to Australian tote wagering. However its one that will provide deep liquidity, stable prices, potentially larger jackpots and a simpler infrastructure which can only be a positive thing for punters.
