If you’ve been matched betting for any length of time, you’ll know that Betfair commission is the silent profit killer. Every time you win a lay bet on the exchange, Betfair takes a cut of your net winnings. And in March 2025, they made that cut even bigger.

This guide breaks down the current commission rates, explains exactly how they affect your matched betting returns, and shares three practical strategies to fight back.

Current Betfair Commission Rates

In March 2025, Betfair increased their commission rates across the board for Australian customers. Here are the current rates as of 2026:

That March 2025 increase might sound small, just one percentage point on racing and sports, but it has a meaningful compounding effect when you’re placing hundreds of bets each month. The NSW/ACT racing rate of 10% has been a persistent pain point and remains the highest commission rate for any Australian market.

How Betfair Commission Works

If you’re new to Betfair, commission can be confusing at first. Here’s the critical thing to understand:

Let’s say you place a lay bet on a horse race. The horse loses (which is what you wanted), and you collect $100 in profit from that market. At the current 8% racing commission rate, Betfair takes $8 and you keep $92.

If the horse had won and you lost money on the market, you’d pay no commission at all.

This is important because it means commission only erodes your winning bets, not your losing ones. Over time, since matched betting relies on having a balanced book, you’re effectively paying commission on roughly half your exchange activity.

Impact on Matched Betting

Here’s where it gets real. Commission directly reduces the value of every matched betting opportunity you find, and it affects both SNR (Stake Not Returned) and SR (Stake Returned) free bets.

How Commission Reduces Your Returns

When you see an SNR value of 80-87% in tools like Bonusbank’s ATM (Automated Trading Machine), those values already factor in the higher commission rates from the March 2025 increase. Before the increase, those same opportunities would have returned slightly more.

Here’s a simplified example of how the increase hits your pocket:

The numbers above are illustrative, but the pattern is clear: small percentage changes compound into meaningful amounts over the volume of bets a typical matched bettor places.

The Commission Discount Field in Bonusbank

If you’re using Bonusbank’s tools, you’ll notice a Commission Discount field in both the ATM and HorsePower tools. This is adjustable, typically set to 0% (no rebate) or 10% (if you have a Betfair commission discount).

This field accounts for any commission rebate you receive from Betfair’s loyalty program. If you do have a discount, make sure this is set correctly so the tool calculates your true expected value.

Betfair Odds Thresholds in HorsePower

Bonusbank’s HorsePower tool is smart about when it uses Betfair place odds. It only incorporates Betfair lay odds when the total matched on the market exceeds $5,000 or the market efficiency is above 90%. Below those thresholds, the odds may not be reliable enough to trade on, which ties directly into the liquidity problem discussed below.

The Liquidity Problem

Commission isn’t the only challenge. Betfair liquidity in Australia is declining, and this compounds the commission problem significantly.

To put concrete numbers on it, the average hold at Flemington, one of Australia’s premier racecourses, has dropped from $904,000 in 2022 to just $372,000 more recently. That’s a decline of nearly 60%.

When you combine higher commission rates with lower liquidity, you get a double squeeze on matched betting profits:

1. Commission takes a bigger bite out of each winning lay bet
2. Low liquidity limits how much you can stake on each opportunity
3. The result is less profit per opportunity and fewer viable opportunities overall

This is the reality of the current Australian matched betting landscape, and it’s why having strategies to mitigate commission impact is so important.

Strategies to Minimise Commission Impact

The good news is that experienced matched bettors, and services like Bonusbank, have developed strategies to work around the commission burden. Here are the three main approaches.

1. Dutching: Bypass the Exchange Entirely

Dutching is the most direct solution to the commission problem. Instead of backing at a bookmaker and laying on Betfair, you back different outcomes across two or more bookmakers. Since you never touch the exchange, you pay zero commission.

This strategy works particularly well for:

• Early payout and bonus bet offers across NRL and AFL
• Situations where bookmaker odds are competitive enough to create a profitable dutch
• Markets where Betfair liquidity is too low to lay effectively

The downside is that dutching requires suitable odds across multiple bookmakers, so it’s not always possible. But when it works, it completely sidesteps the commission issue.

2. Use Commission Discount Rebates

Betfair offers a tiered discount program that can reduce your effective commission rate. If you qualify for a discount, you’ll pay less on every winning market, and that saving adds up quickly across hundreds of bets.

Make sure you:

• Check your current discount tier in your Betfair account settings
• Update the Commission Discount field in Bonusbank’s tools to reflect your actual rebate
• Focus your volume through Betfair to maintain or improve your discount tier

More detail on how the discount tiers work is covered below.

3. Focus on Higher-EV Opportunities

When commission takes a bigger bite, the logical response is to be more selective about which opportunities you pursue. Prioritise bets with a higher expected value (EV) to offset the commission drag.

In practice, this means:

• Using Bonusbank’s ATM to sort by EV and focus on the most profitable opportunities first
• Not wasting time on marginal plays where commission eats most of the edge
• Taking advantage of big event promotions (Melbourne Cup, AFL Finals) where bookmakers offer more generous terms

Betfair Commission Discount Programs

Betfair offers a tiered commission discount based on your betting volume. The more you bet, the bigger the discount you receive on the base commission rate.

The exact tiers and requirements change from time to time, so always check your Betfair account for the latest details. However, the general structure works like this:

• Base rate: The standard commission rates (8% racing, 6% sports, 10% NSW/ACT racing)
• Discount tiers: Based on the total commission you’ve generated, Betfair applies a percentage discount to the base rate
• Calculation: Your discount is applied to the base rate. For example, a 10% discount on the 8% racing rate means you’d pay 7.2% instead

For most matched bettors, achieving the higher discount tiers requires significant volume. It’s worth pursuing if you’re a serious bettor, but don’t count on massive savings unless you’re placing a large number of bets regularly.

What This Means for Beginners

If you’re just getting started with matched betting, don’t let commission scare you off. Yes, it’s a cost of doing business, but matched betting remains one of the best risk-free side hustles available in Australia.

Here’s what beginners should know:

1. Commission is already factored in. Tools like Bonusbank’s ATM show your expected value after commission, so you’re seeing realistic numbers
2. Welcome offers don’t rely heavily on Betfair. Many welcome bonus strategies use dutching or other approaches that minimise exchange exposure
3. It gets easier. As you build experience, you’ll naturally learn which opportunities are worth pursuing and which aren’t
4. The maths still works. Even with 8% commission, matched betting is profitable. The returns are just slightly lower than they were before March 2025

The Bottom Line

Betfair commission is an unavoidable cost of matched betting in Australia. The March 2025 increase to 8% on racing and 6% on sports (with 10% on NSW/ACT racing) has reduced returns across the board. Combined with declining liquidity, it’s a tougher landscape than it was a few years ago.

But matched betting is still profitable. The key is to adapt your strategy:

• Dutch where possible to avoid commission entirely
• Use your commission discount and make sure your tools reflect it
• Focus on quality over quantity. Chase the best opportunities, not every opportunity

With the right approach, commission becomes a manageable cost rather than a deal-breaker.
