Most Aussies renew before they fly. But if you are already in Cambodia and the 6-month rule suddenly matters — extension paperwork, onward border, surprise side-trip — DFAT consular through the Australian Embassy in Bangkok handles emergency renewals on roughly a 2-week clock. Your existing eVisa survives the renewal because it is keyed to passport number not expiry date, but the new passport number breaks the link for your next trip.

First, the practical reality: most Aussies should renew BEFORE travel, because Cambodia enforces a 6-month validity rule at the airline gate in Sydney. If you are already in Cambodia and the expiry suddenly bites (extension paperwork, onward land border, surprise side-trip to Bangkok), DFAT handles emergency renewals through the Australian Embassy in Bangkok — the Phnom Penh consulate refers to Bangkok for full passport replacements. Ring the DFAT Consular Emergency Centre on +61 2 6261 3305 first, expect a ~2 week clock for a full replacement ($400-600 AUD) or 24-48 hours for an Emergency Travel Document ($150-200 AUD) for a single onward journey. Your existing Cambodia eVisa is keyed to the passport number, not the expiry — so your current 30-day stay keeps working until you leave, but any future Cambodia trip needs a fresh $80 USD (~$122 AUD) eVisa application against the new passport number.


Mid-trip departure-then-return is the real trap
If your trip involves leaving Cambodia mid-trip (a Bangkok side-trip, a Vietnam border run, a Laos overland) and then re-entering Cambodia, your old eVisa was already a single-entry document so it would not cover the re-entry regardless. But with a new passport number after the renewal, you cannot even apply for the re-entry eVisa under the old number — you must apply fresh against the new passport, which Cambodian Immigration will not be able to do until your renewal is complete. Plan the side-trip after the renewal lands, not before.
