Should Aussies extend their Cambodia visa or apply for a fresh eVisa? It depends on shape. Tourist holders always need a fresh eVisa (the extension path ended November 2025). Business holders can extend in-country OR reapply — and the maths is genuinely close on some trip patterns.

Depends on shape. EXTEND if: you're on the Business eVisa (E-Class), you want continuous stay >30 days, you'd rather not leave and return. FRESH eVISA if: you're on the Tourist eVisa (cannot extend), you want to leave Cambodia for a side-trip and re-enter, or your stay needs are <30 days at a time over multiple visits. Tourist extensions ended in November 2025, so Tourist holders ALWAYS need a fresh eVisa for a longer/repeat stay ($80 USD / ~$122 AUD per application). Business eVisa holders can extend ($50–400 USD depending on length) OR apply fresh — the math depends on multi-entry need and trip count.
This is the honest decision guide for Aussies in 2026 — when to extend, when to reapply, and how the maths actually shakes out across the most common trip patterns. If you have not yet booked the underlying visa, the Cambodia eVisa application is the place to start, and the Australia country pillar covers the wider eligibility picture for permanent residents and dual citizens.
For most Aussie leisure travellers this is fine — a fresh Tourist eVisa is $80 USD (~$122 AUD), processed in 3 business days, delivered as a printable PDF by email. The Cambodia Tourist visa for Australians guide has the full application detail. If you suspect you might want to stay longer or do anything business-adjacent on the trip, the cleaner move is to apply for the Business class upfront before you fly out of Australia.
If you entered on the Business eVisa, you genuinely get to choose. Extension lengths of 1, 3, 6, and 12 months are all available through a Cambodian immigration agent in Phnom Penh or Siem Reap, and the per-month rate gets cheaper as the length goes up. The Cambodia Business visa extensions guide for Australians has the full mechanics on the underlying extension flow. The flip side is that nothing forces you to extend — you can also just leave Cambodia at day 30 and re-enter later on a fresh Business eVisa. Whether that's cheaper depends on how many re-entries you'd actually make.

Two patterns stand out across the three scenarios. First, for any continuous stay over 30 days the extension flow on the Business class is the right answer regardless of cost — you cannot stay legally without it. Second, for stays of 30 days or less, even when there are multiple of them in a year, the fresh Tourist eVisa is almost always cheaper and simpler than going through the Business class. The Cambodia eVisa multiple-entry for Australians guide has the line-by-line breakdown for the repeat-Tourist pattern.

The Phnom Penh and Siem Reap immigration agent ecosystem is mature and the paperwork is routine, but choosing the right agent matters. The Cambodia visa extension agents in Phnom Penh for Australians guide covers what to look for and what to walk away from. Either path requires the e-Arrival Card at every air arrival, which is worth getting right before each entry.

One more case worth flagging: the long-stay strategy switch. If you find yourself rebooking Cambodia trips every quarter, the Cambodia frequent traveller visa strategy for Australians guide is worth a read — it covers the maths on switching from repeat-Tourist to Business-plus-extension as your trip count goes up. And if you're already in the long-haul camp at the 12-month end, the Cambodia 12-month visa extension for Australians piece has the dedicated breakdown.

The honest summary for Aussies: Tourist holders always need a fresh eVisa for any second stay, Business holders genuinely choose between extending and reapplying based on trip shape, the extension flow wins for continuous stays over 30 days, and repeat fresh eVisas win for spread-out short trips. The Do Australians Need a Visa for Cambodia pillar covers the basic eligibility frame if you haven't sorted the underlying visa yet, and Australia's Smartraveller advisory is the right first call from a government standpoint before you fly.
If you've not yet booked the underlying visa, the Australian apply page handles either class — Tourist at $80 USD (~$122 AUD) or Business at $90 USD (~$137 AUD) all-in, both 3 business days. Pick the class that matches the longest trip you might want this calendar year, not the trip in front of you. That single decision saves most of the extend-or-reapply admin downstream.
