CoinSpot and OKX compared on what decides the bill for an Australian: the real cost of an AUD buy, whether there is an AUD book to trade against, and who you are contracting with.

Three costs kept apart, because they are not the same thing: the published trading fee, the AUD conversion a venue with no AUD book forces on you, and the measured cost of crossing its order book. Click any route for the detail.
Execution. Priced by quote. CoinSpot's buy/sell gap sits on top of the 1% and is not published as a rate, so the true all in is above the figure shown.
The default interface, and for most of CoinSpot's catalogue the only one. A flat 1% per trade, each way. CoinSpot does not disclose its Instant quote spread, so this figure is a floor rather than a ceiling.
Execution. Crosses the CoinSpot BTC/AUD book. It is thin and one-sided: at the last reading a single resting order was most of the sell side. Crossing costs more than the fee does.
The 0.1% is the fee alone, on 16 advertised pairs. Measured against CoinSpot's own 1% Instant Buy, only 6 of those pairs actually come out cheaper once you cross the book. This route works for BTC, ETH and a handful of majors, in small size.
Execution. Crosses its own AUD book, measured below.
Taker rate plus the measured cost of crossing the book.
Execution. Posting rather than taking avoids the crossing cost entirely.
You pay the maker rate and no spread, at the price of an uncertain fill.

CoinSpot advertises a 0.1% fee on its Markets order book, against 1% on Instant Buy. The fee is real. The cost is the fee plus crossing the book, and on most of these pairs the book is barely there. Every pair below was walked on 26 July 2026 at a A$1,000 order.
For an AUD buy, OKX. Past that it depends on what you are doing.
These two are scored here for one job: an Australian funding an account in Australian dollars. The pillars above re-weight the same evidence for that reader, which is why they can disagree with the global Coindaily Score.
OKXCoinSpotOKXCoinSpotOKXOrder book depth is the least stable figure on this page and the easiest to re-check: the measurements here are a single snapshot. Fees and licence conditions change too, so click through to a source on any row that matters to your decision.
On the default route each one puts in front of you, OKX. It lands at about 0.1% all in against 1%. Those figures are the published fee plus, where the platform has no AUD order book, the cost of converting Australian dollars first. Where we could walk a live book, the measured cost of crossing it is included too.
CoinSpot. We walked both public AUD order books on the same day. Crossing CoinSpot's cost a measured 0.101% on a A$10,000 order against 0.185% on OKX. Depth matters as much as the fee: a low fee into a book that is not there costs more than a higher fee into one that is.
Both are on the AUSTRAC register. On our trust pillar, which weighs licensing, custody, audits and enforcement history from the sourced facts on each review, CoinSpot scores 78 and OKX scores 86. AUSTRAC registration is anti-money-laundering registration, not a financial services licence, and it says nothing about whether your balance is protected.
CoinSpot scores 90 and OKX scores 80 on asset range, which counts what is listed and weighs how much of it is actually reachable in Australian dollars. A large catalogue priced only against USDT is worth less to an Australian buyer than a smaller one priced in AUD.
Yes, and plenty of Australians do: one platform as the AUD door, the other as the trading venue. Moving crypto between them costs a network fee, so it is only worth the extra step if the fee gap covers it. Both report to AUSTRAC and the ATO's data matching program either way.
