In 2026, the Electronic Travel Authority (ETA, Subclass 601) itself has no government "visa fee," but there is a mandatory high-fidelity service fee of AUD 20 (approximately $13–$15 USD) for applications submitted through the official Australian ETA app. This fee covers the high-fidelity digital processing and biometric verification required for the 12-month multi-entry permit. For those not eligible for the ETA, the Visitor Visa (Subclass 600) carries a much higher high-fidelity cost, starting at AUD 190 for offshore applications. For 2026 travelers from eligible countries like the U.S., Canada, or the UK, the AUD 20 fee is a high-fidelity bargain, providing nearly instant authorization for tourism or short-term business visits. It is a high-fidelity requirement to use the official mobile app for the lowest price, as third-party agencies often charge significant "High-Fidelity" convenience markups that can triple the total cost.
