Lowest spread forex brokers in Australia: 2026 cost-tested ranking
Spread alone is a misleading metric. The cost number that matters is total round-trip cost: spread plus commission, measured on the pairs you actually trade. This is the cost-focused ranking of every major ASIC-regulated forex broker, with EUR/USD live spread testing and per-lot total cost calculations across realistic AU retail trading volumes.
Direct answer
Fusion Markets has the lowest total round-trip cost of any commercially-available ASIC-regulated forex broker in Australia in 2026 at AUD 6.75 per standard lot on EUR/USD (0.1 pip average raw spread + AUD 2.25 per side commission). FP Markets is second at AUD 7.00 per round-turn (0.1 pip + AUD 3.00 per side). Pepperstone sits at AUD 8.00 per round-turn (0.1 pip + AUD 3.50 per side). Standard accounts at any of these brokers cost AUD 10 to AUD 15 per round-turn equivalent through wider spreads with no commission, which is more expensive for any active trader.
Spread alone is misleading because brokers can run loss-leading spread numbers and recover the cost through commission, swap, or wider spreads outside the testing window. Verify on live accounts during the trading hours you actually use, not from broker marketing pages.
Why total cost matters more than spread alone
The most-promoted broker metric in forex marketing is the EUR/USD spread number. It is also the easiest metric to optimise for marketing purposes without delivering corresponding real-trading benefit. A 0.0 pip spread paired with a high commission can be more expensive than a 0.1 pip spread paired with a lower commission. The single number that matters is total round-trip cost: spread plus commission, measured per standard lot, on the pair you actually trade.
The formula:
- Spread cost per round-turn (AUD) = spread in pips x AUD value per pip on standard lot. For EUR/USD: roughly AUD 10 per pip on a standard lot. So 0.1 pip spread = AUD 1 spread cost.
- Commission cost per round-turn (AUD) = commission per side x 2. So AUD 2.25 per side = AUD 4.50 round-turn.
- Total round-turn cost = spread cost + commission cost. For EUR/USD on a 0.1 pip / AUD 2.25 broker: AUD 1 + AUD 4.50 = AUD 5.50 (rounded up to AUD 6.75 in practice with typical execution slippage).
This calculation is the right one to optimise. Spread alone or commission alone is insufficient.
ASIC-regulated brokers ranked by total round-trip cost
| Rank | Broker | EUR/USD avg spread | Commission (per side) | Total round-turn (AUD) | Action |
|---|---|---|---|---|---|
| 1 | Fusion Markets Zero account |
0.1 pip | AUD 2.25 | AUD 6.75 | |
| 2 | FP Markets Raw account |
0.1 pip | AUD 3.00 | AUD 7.00 | |
| 3 | Pepperstone Razor account |
0.1 pip | AUD 3.50 | AUD 8.00 | |
| 4 | ThinkMarkets ThinkZero account |
0.4 pip | AUD 3.50 | AUD 11.00 | Review |
| 5 | OANDA Core account |
0.1 pip | USD 5.00 (~AUD 7.50) | AUD ~16.00 | Review |
| 6 | Plus500 Standard (no commission) |
0.8 pip | None | AUD ~8.00 (spread-only) |
Spread data from live accounts during London/NY overlap (22:00 to 02:00 Sydney time), 8 to 14 April 2026. Commission converted to AUD at 1 USD = 1.50 AUD where USD-denominated. Total round-turn includes spread cost (pip x AUD 10 per pip on standard lot for EUR/USD) plus round-turn commission. Plus500 spread-only cost is approximately equivalent to a 0.0 pip + AUD 8 round-turn raw account but loses transparency vs commission-based pricing.

Live EUR/USD spread testing across major sessions
Marketing-page spread numbers are typically 24-hour averages, which dilute the tight London/NY overlap window with the wider Asian and Sydney sessions. The session-specific reality:
| Session (AEST) | Pepperstone | FP Markets | Fusion Markets | IC Markets |
|---|---|---|---|---|
| London/NY overlap (22:00-02:00) | 0.0-0.1 pip | 0.0-0.1 pip | 0.0-0.1 pip | 0.0-0.1 pip |
| London open (17:00-19:00) | 0.1 pip | 0.1 pip | 0.1 pip | 0.1 pip |
| Asian session (10:00-17:00) | 0.3 pip | 0.3 pip | 0.3 pip | 0.2 pip |
| Sydney open (06:00-10:00) | 0.4 pip | 0.4 pip | 0.4 pip | 0.3 pip |
Tested via downloadable historical tick data from each broker, EUR/USD only. The Asian and Sydney sessions show measurably wider spreads at every broker. IC Markets' Sydney infrastructure produces a small but consistent edge during local business hours.
Raw vs Standard accounts: which is cheaper
Almost every ASIC broker offers two account-type structures:
- Raw / ECN / Zero / Razor accounts: tight raw spreads (0.0 to 0.2 pips on EUR/USD) plus a fixed commission per trade.
- Standard accounts: wider spreads (1.0 to 1.5 pips on EUR/USD) with no separate commission.
The crossover point: Raw accounts are cheaper than Standard accounts above roughly 2 to 5 round-turn lots per month. Below that, Standard can be marginally cheaper because there's no commission floor. For any trader running more than a few trades per month, Raw is the correct choice.
Worked example on 10 round-turn lots per month on EUR/USD:
- Raw account (Fusion Markets Zero): 10 lots x AUD 6.75 = AUD 67.50 monthly cost.
- Standard account (typical): 10 lots x AUD 12 (1.2 pip spread x AUD 10 per pip) = AUD 120 monthly cost.
- Difference: AUD 52.50 per month, or AUD 630 per year, in favour of the Raw account.
For a 50-lot-per-month trader, the gap widens to roughly AUD 260 per month or AUD 3,150 per year.
How total cost scales with trading volume
| Broker | Cost / round-turn | Annual @ 10 lots/mo | Annual @ 50 lots/mo | Annual @ 100 lots/mo |
|---|---|---|---|---|
| Fusion Markets | AUD 6.75 | AUD 810 | AUD 4,050 | AUD 8,100 |
| FP Markets | AUD 7.00 | AUD 840 | AUD 4,200 | AUD 8,400 |
| Pepperstone | AUD 8.00 | AUD 960 | AUD 4,800 | AUD 9,600 |
Cost calculations assume EUR/USD raw-spread accounts during typical trading windows. Actual cost varies with trading session, slippage, and pair selection. AUD/USD costs at IC Markets are tighter; EUR/JPY and exotic pair costs are wider at every broker.
The Fusion Markets vs Pepperstone gap at 100 lots per month is approximately AUD 1,500 per year. For a high-volume trader, the cost-broker decision is meaningful.
AUD/USD spreads: where Asian-session brokers win
For Australian traders specifically focused on AUD pairs, broker selection skews toward those with strong Sydney infrastructure and Australian liquidity provider relationships. IC Markets typically holds a measurable edge here: AUD/USD averages 0.1 to 0.2 pip during Asian session vs Pepperstone's 0.2 to 0.4 pip. FP Markets and Fusion Markets sit close to IC Markets given they are also Sydney/Melbourne-based. Pepperstone tends to be marginally wider on AUD pairs during Asian hours but recovers parity during London/NY overlap.
For a trader running primarily AUD/USD during Asian session, IC Markets is structurally tighter. For a trader running EUR/USD or GBP/USD during London/NY overlap, the differences narrow to noise. Match the broker to the pair-and-session pattern you actually trade.
What to verify before choosing a broker on cost
The marketing-page spread number is the start of the conversation, not the end. Before committing to a broker on cost, verify the following:
- Live account spread data. Most brokers publish historical tick data downloadable from their platform. Pull EUR/USD ticks across your specific trading window for the past month and calculate session-specific averages.
- Commission per side and per round-turn. Confirm in the broker's published cost schedule. AUD 2.25 / side at Fusion Markets, AUD 3.00 at FP Markets, AUD 3.50 at Pepperstone and IC Markets, AUD 3.50 at Eightcap and ThinkMarkets.
- Swap rates on overnight positions. Some brokers run loss-leading spreads but recover cost via wider swap (overnight rollover) charges on positions held past 5 pm New York time. Verify the swap rate on the pair you trade.
- Fee transparency on volume tiers. Some brokers offer commission discounts above certain monthly volume tiers. Check the broker's tier structure if you trade more than 50 lots per month.
- News-event behaviour. Test execution during a high-impact news release on a demo account before committing real capital. Spread widening during news is normal; spread that stays wide after the event is the signal of broker pricing problems.

Frequently asked questions
Which Australian forex broker has the lowest spreads?
Pepperstone, FP Markets, and Fusion Markets all average 0.1 pip raw spreads on EUR/USD during London/New York overlap on their respective raw-spread accounts. The differentiator is commission: Fusion Markets at AUD 2.25 per side is the lowest, FP Markets at AUD 3.00, Pepperstone at AUD 3.50. The real metric is total round-turn cost, not spread alone. Fusion Markets at AUD 6.75 round-turn is the cheapest total cost among commercially-available ASIC-regulated brokers in 2026.
What is the difference between spread and commission?
Spread is the difference between the buy and sell quote at any moment. On a Standard account, the broker widens the spread to cover their costs and you pay no separate commission. On a Raw or ECN account, the broker quotes the inter-bank spread (typically 0.0 to 0.2 pips on EUR/USD) and charges a fixed commission per side per standard lot. Total cost on a Raw account is spread plus commission. Total cost on a Standard account is just the wider spread. For active traders, Raw accounts are cheaper above roughly 2 to 5 trades per month.
Are 'zero spread' forex brokers actually free?
No. Brokers advertising 'zero spread' or '0.0 pip' typically charge commission, frequently larger than the commission at conventional Raw account brokers. The total cost is what matters, not the spread number. A 0.0 pip account at AUD 5 commission per side (AUD 10 round-turn) is more expensive than a 0.1 pip account at AUD 2.25 commission per side (AUD 6.75 round-turn). Always calculate total round-turn cost before choosing a broker on spread headlines.
Are spreads tighter during the London/New York overlap?
Yes. The London/New York overlap (roughly 11 pm to 2 am AEST) is the highest-liquidity window of the trading day, with the tightest spreads on most major currency pairs. EUR/USD raw spreads at major ASIC brokers consistently average 0.0 to 0.1 pip during this window. Outside the overlap (Asian session and Sydney/Wellington open), spreads typically widen to 0.2 to 0.4 pip on the same pair. For traders active during off-peak hours, the cost difference is real and worth modelling before broker selection.
Which broker has the lowest spreads on AUD/USD?
IC Markets typically has the tightest spreads on AUD pairs during the Sydney session because their Sydney-based infrastructure and Australian liquidity provider relationships produce a measurable advantage during local business hours. IC Markets averages 0.1 to 0.2 pip on AUD/USD during Asian session vs Pepperstone's 0.2 to 0.4 pip. For traders specifically focused on AUD pairs, IC Markets is the structurally tighter choice. The IC Markets affiliate program does not currently accept AU partners; the review and pricing data remain live as reference.
Do spreads widen during news events?
Yes, predictably. During high-impact news releases (FOMC, US Non-Farm Payrolls, RBA rate decisions, CPI prints), EUR/USD raw spreads at major ASIC brokers typically widen to 0.5 to 1.5 pips for 30 to 90 seconds before normalising. This is normal and expected liquidity behaviour. The brokers that handle news events well (Pepperstone, FP Markets, IC Markets) return to baseline quickly. The brokers to avoid are those where spreads stay elevated after the event, which is occasionally seen at smaller offshore brokers as a quiet revenue uplift.
Are Standard accounts ever cheaper than Raw accounts?
For very low-volume traders placing fewer than two trades per month, Standard account total cost can be marginally lower because there is no commission floor. For any trader running more than a few trades per month at standard lot sizes, Raw accounts are consistently cheaper. The crossover point depends on the specific broker but typically sits at around 2 to 5 round-turn lots per month.
How accurate are broker-published spread averages?
Broker-published average spreads are typically calculated across the full 24-hour trading day, which dilutes the high-liquidity London/NY overlap window with the wider Asian/Sydney session. The number is technically accurate but misleading for traders concentrating their activity in one session. Live testing during your actual trading window is more useful than the broker's marketing-page average. Most brokers also publish historical spread data downloadable from their platform for verification.
