If you've already been to Cambodia twice this year and you're looking at trip three, the rules don't get any cheaper or any easier. There's no loyalty discount, no multi-entry upgrade for tourists, and the same single-entry eVisa each time. Here's when it actually pays to switch to Business.

From your third Cambodia trip in 18 months, switch to the Business eVisa at $90 USD all-in (~$137 AUD). Cambodia's Tourist eVisa is single-entry every time at $80 USD (~$122 AUD), with no loyalty discount, no multi-entry upgrade, and a hard 30-day stay cap — three Tourist runs cost $240 USD (~$366 AUD) and rebuild themselves from scratch each time. The Business eVisa is only $10 USD (~$15 AUD) more per trip, supports meetings, conferences, supplier visits, sales calls and long stays, and is the only Cambodia visa that can be extended into multi-entry 1-, 3-, 6- or 12-month blocks once you arrive. Approved in 3 business days, delivered as a printable PDF by email, with free resubmission if Immigration flags a correction.
Our second-visit guide for Australians walked through what changes between trip one and trip two. By trip three the calculus shifts again, because the Tourist eVisa is no longer the obvious default. If your pattern is more than two Cambodia trips in 12 months, the frequent-traveller strategy guide for Australians lays out the four common shapes — quarterly business runs, blended business-and-beach, partner visits, and slow loops — and which visa fits each one. The smoothest way to get sorted before your flight is to Cambodia visa application for Australians on our site.

If you want the full cost breakdown side-by-side, the Cambodia eVisa business-vs-tourist cost difference guide lays out the per-trip and annual numbers for both products. The Cambodia eVisa multi-entry guide walks through exactly how the 6- and 12-month multi-entry extensions work in practice for Australian passports.
