Matched Betting Vocabulary


Here are some of the common terms you will need to know when Matched Betting in Australia:

  • Backing

    Placing a back bet on an event. This is a bet that something will happen i.e. if i back Barcelona against Real Madrid this means that i think Barcelona will win.

  • Laying

    Betting that something will not happen i.e. if i lay Barcelona against Real Madrid this means that i think Barcelona will not win.

  • Odds

    Odds show the probability of an event occurring. They also show how much return we will receive if we place a bet at those odds and it wins. E.g. A bet at odds of 2.00 is likely to win 1 out of every 2 times (probability of 50%), if we bet $1 at odds of 2.00 we will receive $2 back from the bookie if we win.

  • Liquidity

    This is the amount of money available for backing/laying on a betting exchange. The liquidity is displayed beneath the odds. When matched betting we want the amount of liquidity to be higher than our bet amount. If the liquidity is lower our bet will only be partially matched and we risk losing money.

  • Bonus Bets

    Also known as Free Bets. These are incentives given out by bookmakers to encourage people to bet with them. They come in different forms but all can be manipulated to guarantee risk-free profit.

  • Qualifying Bets

    These are bets placed in order to earn Bonus Bets. These bets usually result in a small loss, known as a qualifying loss or QL.

  • Arbitrage

    An arbitrage bet, or arb, is a back bet that can be instantly laid off at the exchange in order to guarantee a profit. This is due to the fact that the back odds are higher than the lay odds.

  • Dutching

    The process of betting on all possible outcomes of an event at different bookmakers. We might do this to guarantee a profit or to potentially qualify for a bonus bet or refund.

  • SR

    This stands for Stake Returned and refers to Bonus Bets that include the Bonus Bet stake when paying out winnings. These bonuses are uncommon in Australia.

  • SNR

    This stands for Stake Not Returned and refers to Bonus Bets that do not include the Bonus Bet stake when paying out winnings. Most bonuses in Australia are SNR. To maximise profits these should be bet at higher odds.

  • SGM

    Same Game Multi. A bet which involves multiple selections on a single event. For example, a bet on Barcelona to win and Messi to score. The multi only wins if both of those things happen. There are regular promos involving this type of bet that we can take advantage of.

  • Value Bets

    These are bets that are not risk-free but which should be profitable for the bettor in the long-term e.g. betting on a coin toss where you are given $2 every time you guess right but only lose $1 when you guess wrong.

  • Wagering Requirements (WR)

    A condition previously attached to bonus bets that required the punter to bet a certain amount before they could withdraw. Now illegal as a result of the National Consumer Protection Framework for Online Wagering in Australia.

  • Liability

    The amount of money that you you can lose when laying a bet at the exchange. It is calculated as stake*(lay odds – 1). When calculating how much you should lay for any matched bet it is important to check that you have enough money in your Betfair account to cover the liability. If you don’t you should find a bet at lower odds.

  • Float

    Also known as your bank. This is the amount of money that you have for matched betting purposes. Your starting bank for matched betting in Australia should be at least $250, but $1000-1500 is ideal. As you progress your profits will be added to your float, allowing you to tackle even more valuable bonuses.

  • Underlay

    A technique where we lay less than the standard amount so that we make more money if our bet wins at the bookie, and less if it wins at Betfair.

  • Expected Value (EV)

    The EV tells us what our average return would be if we placed the same bet, or combination of bets, an infinite number of times. By only placing bets with a +EV we ensure that we come out ahead in the long-run.

  • Variance

    Although +EV bets guarantee a long-term profit, there can be ups and downs along the way. This is known as variance.
