Gambling is woven into Australia’s cultural fabric—yet beneath the bright lights of casinos and online betting lies a staggering reality. In 2022–23, Australians placed an estimated AUD $244.3 billion in bets, with losses soaring to around $31.5 billion. (Source: Wikipedia)
But while many dream of beating the odds, the question remains: is long‑term success truly possible?
In this post, we’ll delve into how much Aussies actually lose, break down the mechanics of gambling returns and odds, and explore whether you can realistically build a long‑term winning strategy.
How Much Do Australians Actually Lose?
| Type | Yearly loss ($AUD) | % of total loss |
| Pokies | $13b | ~52% |
| Lotteries | $3b | ~12% |
| Horse Racing | $5b | ~20% |
| Sports Betting | $4b | ~16% |
| Total | $25b |

Why The House Always Has The Edge
Here we break down the math behind casino and bookmaker profitability. Whether it’s pokies with built-in payout percentages or sports bets that skew in the bookies’ favour, this section explains why gambling is statistically designed to work against the player.
Key Definition 1: Expected Value
The expected % return of a bet
Example 1: Bet $10 on a fair coin flip
Win $10 if it lands on heads (50% probability)
Lose $10 if it lands on tails (50% probability)
EV is (50% x $10) + (50% x – $10)
= $5 – $5
= $0, and $0/$10 strake = 0% EV
Example 2: Bet $10 when Bookies $1.90/$1.90 in a 50/50 game
Win $9 profit if you win (50% probability)
Lose $10 if you lose (50% probability)
EV is (50% x $9) + (50% x -$10)
= -$0.50, and $0.50/$10 = -5% EV
Key Definition 2: Open Form System vs Closed Form System
Closed form system
- A gamble in which the payouts, probabilities and expected values are mathematically defined and known
- House edge is 100% defined
- It cannot be beaten over the long term.
Open form system
- A gamble in which outcomes and probabilities can only be estimated.
- House edge can only be estimated.
- It’s possible to beat the /bookies in the long term as sometimes bookies’ probability estimates are wrong enough to outweigh bookie margin.
1. Poker Machines
- Aus has ~20% of all pokies in the world yet only 0.3% of the global population.
- The only fair spin you get is a black/red gamble which is a true 50/50
- We imputed the algorithm code from a commonly played poker machine into a Monte Carlo simulator and this is what the PNL looks like. The x-axis has the number of spins and the y-axis the PNL with a starting bankroll of $1000.
- Annual losses in Australia: $13b AUD, 50% of total gambling loss
- Expected Value: -10% to -18%
- Closed form system
- Possible to win long term = NO
2. Lotteries
- Here we’re talking about Lotto, Powerball, scratchies etc
- Annual losses in Australia: $3b AUD, making up 12% of total gambling loss
- Expected value: -30% to -50%, with some rare jackpot exceptions
- Rare exceptions: Only very rare cases of edge is situations of jackpot accumulation.
3. Horse Racing
- Australians are the biggest racing punters in the world
- Annual losses of $5b AUD, making up 20% of total gambling loss
- Expected value -12% to -25% (depending on how close to top price you get and how margin is skewed). Tote is a closed form mathematically impossible system to beat
- Tote = closed form system
- Fixed odds = open form system
- The best syndicates win at 3-4% in fixed racing
- Tote is impossible to win at long term unless you have a special deal with the operator of the Tote such as a big Aussie syndicate has with the TAB
- Possible to win long term? The best syndicates win at 3-4% so it is possible, but it’s very hard.
4. Sports Betting
- Annual losses of $4b AUD, making up 16% of total gambling loss
- Expected value -5% to -20% depending on margin which varies greatly amongst sports betting options. The lowest margin product is often the $1.90 vs $1.90 line or totals markets which if you assume are a coin toss have an EV of 1/1.9 + 1/1.9 – 1 = 5.26%
- Open form system
- Possible to win = YES, but hard given no minimum bet laws
So Can You Win Long Term?
Elements To Win
- Quantifiable Edge
- Volume that you can get on
How Much Can You Get On Defined By
- Betfair: Just a liquidity consideration
- Bookies
Factor 1: Tiering of the event: Tier 1 events have highest betting limits
Factor 2: Buckets Bookies put punters into:
– Mug (5-10x normal limits)
– Standard Punter (normal limits)
– Sharp (1-10% of normal limits and manual acceptance of all bets required sometimes)
Common Approaches To Trying To Win At Fixed Odds Racing and Sports Betting
- Form
Possible but hard, need to beat 15-30% margin. Margin has increased in recent years too due to point of consumption tax. Best win at around 4% pot.
Conclusion: super hard - Latency edge
Big syndicates. Bookies don’t like this and often cancel bets but beating exchanges is possible.
Conclusion: easy money for a while then bookies ban you - Arbing (Bookie vs Bookie or Bookie vs Betfair)
Conclusion: Bookies use arb detection software so you get limited - Price mover sniping
Eg Momentum Alerts but bookies hate this business.
Conclusion: 1-3% edges are constant but the bookies reduce limits very quickly. - Promotion arbitrage
- Promotion Pure Arbitrage: Uses Betfair or Bookie vs Bookie strategies to lock in promotional value. Conclusion: Typical edge is 10% but bookies quickly identify Betfair and top price arbitrageurs these days
- Promotion Statistical Arbitrage:
Involves identifying value bets on a standalone basis and overlaying them with promotional value as insurance. This is what Edge Alerter does.
Conclusion: Edge is typically around 20-25% and it’s more sustainable because you’re not top price shopping bookies nor arbing them on Betfair, plus if you bet late the bookies don’t detect you as easily.

| Sports Betting | Open | -5% to -20% |
