Arbitrage Betting Tips: A Practical Day-to-Day Workflow for Australian Punters

By the AUOdds team · Updated 27 Oct 2026 · 7 min read

These arbitrage betting tips focus on the part most guides skip: the daily workflow that turns a lock on screen into two placed bets at the right prices. The maths is the easy bit. The hard part is speed, order and accuracy when a price only lasts minutes. AUOdds data shows 3,145 locks across 9 bookmakers in the last 30 days, with a typical lock of about 1.5%. Margins that thin leave little room for a slow deposit, a wrong stake or a skipped recheck. This guide walks through account preparation, which leg to place first, rechecking, rounding, staying active longer, record-keeping and responsible-gambling settings. Every tip suits licensed Australian bookmakers and pre-match markets only.

What do good arbitrage betting tips look like day to day?

Most 'arbitrage betting how to' guides stop at the formula. They show you how to add up implied probabilities and then leave you to it. In practice, the formula is the easy part. What decides whether you actually lock in a return at the prices shown is your routine.

A workable daily routine looks like this:

• Before the day: check balances, confirm every account is verified and set your maximum stake per lock.
• When a lock appears: check the event, market and selection names match exactly across both bookmakers.
• Placing: take the leg most likely to move first, then recheck and place the second.
• After: screenshot both bet slips and log the bet in your record.

Some generic tip lists you'll find online were written for overseas markets. They suggest in-play arbing or opening extra accounts. Neither belongs in an Australian workflow. Online in-play sports betting isn't offered to Australians, so every lock you act on should be pre-match. Holding more than one account with the same bookmaker, or betting through someone else's account, puts your balance and your account at risk.

The aim is to make every step boring and repeatable. When the routine is automatic, you can act within the short window a price is available, and you make fewer mistakes under time pressure.

How should you prepare accounts before a lock appears?

Locks don't wait for a bank transfer to clear. If you see a lock and then have to deposit, verify your ID or reset a password, the price has often gone by the time you're ready.

Get these sorted before you start:

• Licensed bookmakers only. Use operators licensed in Australia. The ACMA lets you check whether a gambling operator is legal, and it's worth doing for any site you haven't used before.
• One account per bookmaker, in your own name. Use accurate details so identity checks pass the first time.
• Verification complete. Upload ID early. A withdrawal held for verification ties up money you need for the next lock.
• Balances spread sensibly. Locks can pair any two bookmakers, so a modest balance in each is more useful than a big balance in one.
• Saved logins and a fast device. A phone and a laptop side by side lets you have both bet slips open at once.

A simple rule many arbers use is to keep enough in each account to cover their usual maximum stake on one leg. If your typical lock uses $250 a side, aim for at least that in every account you plan to use.

Check balances again after each settled event. Winnings land in one account and losses come out of another, so your money drifts. A quick rebalance once or twice a week stops you missing a lock because one account has run dry.

Which leg should you place first?

Place the price most likely to move first. Usually that's the outlier: the bookmaker offering odds noticeably better than the rest of the market. Outlier prices tend to be corrected quickly, while the price on the other side is often in line with most bookmakers and less likely to shift.

Worked example (AFL head-to-head):

• Team A at 2.05 with Bookmaker 1 (most others have it at 1.95)
• Team B at 2.01 with Bookmaker 2

Implied probabilities: 1 ÷ 2.05 = 0.4878 and 1 ÷ 2.01 = 0.4975. The total is 0.9853, which is under 1, so the market locks at about 1.5%.

For a $500 total outlay, the exact stakes are about $247.54 on Team A and $252.46 on Team B. Either result returns about $507.45.

The 2.05 is the outlier, so place that leg first. If it's accepted, move straight to the 2.01.

If the price changes or the bet is rejected on the first leg, you've lost nothing. Simply skip the lock. That's the whole point of ordering: the riskier leg goes first, while walking away still costs you nothing.

An AUOdds alert lists the exact stake for each outcome, but you still choose the order. Get into the habit of asking which price looks out of step with the market before you click anything.

Why recheck before the second leg, and how do you round stakes?

Prices refresh constantly. Even with prices about 10 seconds old, a lot can change in the time it takes to place the first leg. Before you confirm the second bet, look at the live price on the bet slip, not the one in the alert.

If the second price has dropped, recalculate. Using the example above, say Team A is placed for $248 at 2.05, returning $508.40. Team B then slips from 2.01 to 1.95. To cover the same return you'd need $508.40 ÷ 1.95 = $260.72 on Team B. Your total outlay becomes $508.72, so you're about $0.32 behind whichever team wins. That's a small, known loss rather than an open bet. It's often better than leaving one side uncovered.

Rounding: exact stakes like $247.54 look unusual. Many arbers round to whole dollars. With $248 and $252:

• Team A wins: $248 × 2.05 = $508.40
• Team B wins: $252 × 2.01 = $506.52

The lowest return is $506.52 against a $500 outlay, so the lock still holds at about $6.52. Always check the lowest return after rounding. On a 1.5% lock, rounding too aggressively can wipe out the margin.

Also check stake limits. If a bookmaker only accepts part of your stake, rebalance the other leg straight away using the accepted amount.

How do you arbitrage bet without getting limited for as long as possible?

Honestly, you can't fully control it. Bookmakers can limit stakes on any account, and arbers are more likely to see it. We cover account restrictions in detail in a separate guide. Here are the workflow habits that help you make the most of the time you have.

• Size stakes to your normal betting. Sudden jumps from $20 bets to $800 bets stand out and also raise your own risk if something goes wrong.
• Use rounded, ordinary-looking stakes. As shown above, whole-dollar stakes usually keep the lock intact.
• Prioritise better locks. With thousands of locks a month, you don't need to take every 0.5% opportunity. Choosing stronger ones means fewer bets for a similar return.
• Spread activity across bookmakers. Rotating which accounts you use avoids hammering one bookmaker every day.
• Never break the rules to keep going. Extra accounts, borrowed identities or misleading details can lead to closed accounts and withheld balances.

Treat limits as a normal cost of arbing, not a failure. When an account's stake limits get too small to be useful, retire it from your rotation and carry on with the others. Plan your bank around the idea that some accounts won't last forever.

What records should you keep?

Good records catch mistakes early and show whether arbing is worth your time. A spreadsheet is plenty. For each lock, log:

• Date, sport, event and market
• Bookmaker, selection, odds and stake for each leg
• Expected lowest return at the time of placing
• Actual result and actual profit or loss
• Notes: price moved, partial stake accepted, bet voided

Review it weekly. Compare expected profit with actual profit. A gap usually means one of three things: legs placed at changed prices, rounding errors, or voided bets that left one side running. Each one points to a step in your routine you can tighten.

Records also matter for tax questions. The ATO's ruling on gambling and betting winnings (IT 2655) and its guidance on gambling winnings explain how winnings are generally treated. For most recreational punters they aren't treated as income, but the position can differ if betting looks like a business. Your records show what you're actually doing, so keep them and get advice for your own situation.

Also keep your bet slip screenshots and bookmaker statements. If a bet is disputed or voided, a timestamped screenshot of the accepted odds is the quickest way to sort it out.

How do you keep arbing within healthy limits?

Arbing involves real money and real risk. Prices move, stakes get limited, bets can be voided and mistakes happen. It also means spending a lot of time on betting sites, so build guardrails into your workflow from day one.

• Set deposit limits in every bookmaker account, matched to the bank you've set aside for arbing.
• Use a separate bank account for arbing money so it never mixes with bills or savings.
• Set a time limit. Decide when you'll check for locks and stick to it, rather than watching alerts all day.
• Watch for drift. If you catch yourself backing one leg and 'seeing how it goes', stop. That's no longer arbing.
