The Bookie's Ledger: 120 secrets from the betting ring, so you know exactly how the bookies take your money, and keep more of it.
Educational only. No tips, no selections, no promise of any outcome.
For 42 years I stood on a box at Randwick, Rosehill and Flemington and watched good blokes do all of that. I took their money. This book shows you exactly how.
Every price carries a margin. A market that adds up to 115% means, over the long run, the bookie keeps about 13 cents of every dollar bet. Here's what that looks like if you put $100 a week through the bookies — that's $5,200 a year:
| How it's bet | Average cost a year |
|---|---|
| Win bets, 110% markets | ≈ $473 |
| Win bets, 115% markets | ≈ $678 |
| Win bets, 120% markets | ≈ $867 |
| The tote, ~15% takeout | ≈ $780 |
| 4-leg multis, 115% a leg | ≈ $2,227 |
Long-run averages, worked out as turnover × (1 − 1 ÷ book) and (1 ÷ book)legs for multis. Any one week can go either way; these are what the margin costs on average over time. Takeout varies by state and bet type.
The book won't make the margin disappear. Nothing can. It shows you where it hides, so you can bet less, skip the worst of it, and keep more of yours.






Every entry has two parts: What bookies know (how it really works) and What to do (how to lose less and stay in control).
I was eight the first time Dad let me carry his bag at Randwick. Frank Mahoney's bag. Heavy leather, stuffed with punters' money. He looked down at me and said, "The book doesn't care who wins, son." Took me twenty years to understand it.
I took over his stand in my twenties and worked it for 42 years: Randwick, Rosehill, Flemington, and every country cup with a crowd and a bar. My clerk Normie wrote every bet in the ledger, and over the long run that ledger always came out our way.
Now my grandson bets on his phone at two in the morning, and nobody's ever told him what he's up against. So I'm telling him, and you. This isn't tips and it isn't a system. No book can turn a punter into someone who comes out ahead. But I can show you exactly how we took your money, so you keep more of yours.

No, and anyone who promises that is selling you something. Over time the margin works against every regular punter. This book shows you how the game really works, so you lose less, bet less, and stay in control.
