Aerodrome in Australia: what it is, what it costs, and what the ATO expects
The dominant exchange on Coinbase's Base network, and a case study in incentive-driven liquidity.
No score — we don't rate venues we can't recommend as an AUD on-ramp

What it actually is
Aerodrome is the central liquidity venue on Base, the Ethereum layer-2 built by Coinbase. Its distinguishing feature is not the swapping — that works like any AMM — but how it attracts liquidity: holders lock the AERO token for voting power and direct token emissions toward the pools they choose. That model concentrates deep liquidity very quickly on a single chain, and ties the token’s value to emissions continuing.
What a swap actually costs
We are not printing a fee percentage for Aerodrome. We could not confirm a current one against the protocol's own documentation, and the secondhand figures that circulate on review sites are copied from each other and go stale. The swap screen quotes the fee for your specific route before you confirm — that is the number that applies to you.
Aerodrome runs separate pool types for volatile pairs and for assets meant to hold the same value, and they do not carry the same fee. Fees are set per pool rather than from a single fixed menu, so the rate depends on the pair you trade. We have not confirmed a current percentage against Aerodrome’s own documentation and will not publish one from secondhand sources — the interface displays the fee for your route before you confirm.

The Australian part nobody writes down
You have no Australian consumer protection here
Aerodrome is not registered with AUSTRAC, holds no AFSL and is not a member of AFCA. If a trade goes wrong, if you approve a malicious contract, or if you send funds to the wrong address, there is no complaints process, no chargeback and no regulator to escalate to. Every exchange we review is AUSTRAC-registered precisely because that difference matters at the moment something breaks.
What the ATO expects
The ATO treats exchanging one crypto asset for another as a CGT event — a disposal of the asset you gave up, valued in Australian dollars on the day it happened. Not when you cash out. On every swap.
A hundred swaps is a hundred CGT events
A centralised exchange hands you a statement at tax time. Aerodrome hands you nothing — a wallet address and a chain of transactions you reconstruct yourself, each needing an AUD value at the moment it occurred. Active traders routinely reach 30 June with hundreds of disposals and no records. That is the strongest argument for crypto tax software if you are going to trade this way, and for understanding the rules before rather than after.
What actually goes wrong
Everything here depends on Base. A problem with that network, or with its sequencer, is a problem with your access to the market.
Deep pools are partly bought with token emissions. Liquidity that arrives for incentives can leave when they change, and the AERO token carries that risk directly.
The standard AMM exposure — approve only what you intend to trade, and revoke permissions you no longer need.
Base is reached by bridging from another chain or withdrawing from an exchange that supports it. Australian dollars never touch Aerodrome directly.
So should you use it?
Relevant if you already hold assets on Base or want tokens native to it. For an Australian buying with AUD it is two steps removed from where your money starts, and each step — exchange, bridge, swap — is a place to lose funds and a taxable event to record.

FAQ
Is Aerodrome available in Australia?
There is nothing to sign up for, so it is not blocked or permitted in the way an exchange is — anyone with a wallet can use it. What matters is that Aerodrome is not registered with AUSTRAC, holds no AFSL and is not a member of AFCA, so none of the consumer protections that apply to an Australian exchange apply here.
Do I pay tax on Aerodrome swaps?
Yes. The ATO treats exchanging one crypto asset for another as a CGT event — a disposal at market value in Australian dollars on the day it happened, not when you eventually cash out. Every swap counts, including stablecoin swaps, and no statement arrives at the end of the year.
Can I use Australian dollars on Aerodrome?
No. There is no AUD deposit and no bank transfer. You buy crypto on an AUSTRAC-registered exchange first, move it to a wallet you control, and only then trade — which means a DEX is an addition to a registered exchange rather than a replacement for one.
Is Aerodrome safe?
The contracts being widely used and long-lived is one kind of safety, and it is real. It is not the kind most people mean. Nobody can freeze your funds and nobody can return them, approvals you sign can move your tokens, and a mistyped address is permanent. Safety here is a property of your own practices rather than of the venue.
Is this better than an Australian exchange?
For buying with Australian dollars, no — a registered exchange is cheaper, simpler and gives you somewhere to complain. Aerodrome is worth understanding when you want assets no Australian platform lists or you want to hold your own keys, and those are narrower reasons than most coverage suggests.
