How to Read MyBet Odds Like a Professional Australian Punter
Every price you see on MyBet is a statement about probability, and your job as a bettor is to decide whether that statement is fair, generous or overpriced. This tutorial walks you through the mechanics of the MyBet odds board step by step, from converting decimal prices into implied probability, through reading margin, to spotting where value sits in Australian markets such as the AFL, NRL and cricket. If you want to follow along with live numbers as you read, the full odds board sits at https://mybet-casino-au.com/ , and every example below maps directly onto what you will see there. No guarantees are offered here, only arithmetic and a repeatable process you can apply to any line, any code and any code.
Step 1 – Convert MyBet Decimal Prices Into Implied Probability
Australian bookmakers quote decimal odds, and decimal odds are the easiest format in the world for probability work because the conversion is a single division. The formula is implied probability = 1 divided by the decimal price. A price of 2.00 returns 1 divided by 2.00, which is 0.50, or 50 percent. A price of 4.00 returns 25 percent. A price of 1.50 returns 66.67 percent. Once you habitually run this division in your head, the MyBet board stops looking like a wall of numbers and starts looking like a set of probability estimates you can audit.
Work through this drill on the MyBet markets you follow most closely. Pick a head to head line, write down each decimal price, and convert all of them before you look at anything else. When you have the raw probabilities in front of you, the next step is to add them up, and that is where margin becomes visible.
Step 2 – Measure the Margin Built Into Every MyBet Line
Add the implied probabilities of every outcome in a market and the total will always exceed 100 percent. The excess is the bookmaker margin, and on MyBet you can calculate it in seconds. Take a two way market priced at 1.90 and 1.90. Each side implies 52.63 percent, the total is 105.26 percent, and the margin is 5.26 percent. Compare that with a market priced at 1.95 and 1.95, where each side implies 51.28 percent and the margin falls to 2.56 percent. The lower the margin, the closer the prices sit to true probability, and the more room you have to find an edge.
Run this calculation across several MyBet markets rather than one. Margins are rarely identical between a major AFL fixture and a niche prop bet, and knowing which markets carry tighter pricing tells you where your analysis is worth the most effort.
- Write down every decimal price in the market before you analyse anything.
- Divide 1 by each price to get the implied probability for that outcome.
- Sum all the implied probabilities into a single total.
- Subtract 100 from that total to get the margin in percentage terms.
- Repeat the sum for a second MyBet market and compare the two margins.
- Record the margin next to the fixture so you can track it over a season.
- Prioritise markets with the tightest margins for your deeper research.
- Treat wide margin markets as entertainment rather than analytical targets.
Step 3 – Strip the Margin and Build a Fair Price
Once you know the margin, you can normalise the MyBet prices to remove it and see the operator’s underlying probability estimates. Take the 1.90 and 1.90 example, where each side implies 52.63 percent and the total is 105.26 percent. Divide each implied probability by the total and you get 50 percent for each side, which corresponds to a fair decimal price of 2.00. Now you have a benchmark. Any price above 2.00 on either side is technically value relative to the MyBet estimate, and any price below it is not.
This normalisation step is the single most useful habit in odds analysis because it separates the operator’s opinion from the operator’s fee. The fee is the margin, the opinion is the normalised probability, and your own research sits between them as the deciding factor.
Step 4 – Compare MyBet Prices Against a Fair Value Benchmark
Value exists when the price you are offered is higher than the fair price implied by your own probability estimate. If your research says a team wins 55 percent of the time, the fair decimal price is 1 divided by 0.55, which is 1.82. A MyBet price of 1.95 is above that benchmark and represents positive expected value. A MyBet price of 1.70 is below it and represents a losing proposition over the long run even if the bet wins on the night.
Expected value is the multiplication that matters most. EV equals your estimated probability multiplied by the decimal price, minus 1. At a 55 percent estimate and a 1.95 price, EV equals 0.55 multiplied by 1.95 minus 1, which is 0.0725, or a 7.25 percent edge per dollar staked. At a 1.70 price the same estimate gives 0.55 multiplied by 1.70 minus 1, which is minus 0.065, a 6.5 percent loss per dollar. The two prices sit 25 cents apart and the difference in outcome is enormous.
| Outcome | MyBet Decimal Price | Implied Probability | Your Estimate |
|---|---|---|---|
| Home win | 1.95 | 51.28 percent | 55.00 percent |
| Away win | 1.90 | 52.63 percent | 48.00 percent |
| Draw | 3.60 | 27.78 percent | 22.00 percent |
| Market total | Not applicable | 131.69 percent | 125.00 percent |
| Raw margin | Not applicable | 31.69 percent | Not applicable |
Step 5 – Read Line Movement on the MyBet Board
Prices on MyBet move because money moves them, and the direction of the move tells you where the weight of opinion sits. A price shortening from 2.10 to 1.85 means the implied probability rose from 47.62 percent to 54.05 percent, a shift of more than six percentage points. A price drifting from 1.80 to 2.20 means the implied probability fell from 55.56 percent to 45.45 percent. Track these shifts over the hours before a fixture and you will see the market’s collective estimate forming in real time.
The professional habit is to note the opening price, the price two hours before the match and the closing price. The gap between your own estimate and the closing price is the most honest measure of whether your analysis added anything. If you consistently beat the close on MyBet, your process is working. If you consistently lose to it, your probability estimates need revising.
Step 6 – Audit Your MyBet Odds Decisions Over a Season
The final step is record keeping, because odds analysis without records is just opinion. Log every bet with the decimal price taken, your estimated probability, the implied probability at the time and the closing price. After a full AFL or NRL season you will have a sample large enough to calculate your average edge and compare it against your actual return. This turns the MyBet odds board into a feedback loop rather than a one way relationship.
- Record the date, fixture and market for every bet you place.
- Note the decimal price you accepted and the implied probability it carried.
- Write your own probability estimate before the event starts.
- Capture the closing MyBet price once the market settles.
- Calculate the edge for each bet as estimate multiplied by price minus 1.
- Sum your edges and compare the total against your actual profit or loss.
- Review the gaps each month and adjust your estimation method accordingly.
- Keep the log separate from your bankroll records so neither distorts the other.
Work through these six steps on a handful of markets each week and the arithmetic becomes automatic. The MyBet board rewards the reader who converts every price into probability, measures every margin and compares every outcome against an independent estimate. That discipline, applied consistently across Australian markets, is what separates a punter who understands odds from one who simply reacts to them.
