Cambodian public holidays close MFAIC and pause your 3-business-day clock. In 2026, Khmer New Year falls 14–16 April — colliding with Anzac Day travel plans. Here's the full holiday calendar mapped against Aussie school terms, with timing buffer for each.

Five Cambodian holiday blocks matter for Australian eVisa applicants in 2026: Khmer New Year (14–16 April), Queen Mother's Birthday (18 June), King's Birthday (30 October to 1 November), Independence Day (9 November), and a handful of smaller one-day closures. During each block, MFAIC's eVisa processing unit is closed and the 3-business-day clock pauses entirely. The Khmer New Year window is the most consequential for Aussies because it overlaps with Anzac Day school-holiday travel planning. The least concerning is Christmas — Cambodia doesn't observe 25 December, so MFAIC processes normally through the festive period. The Cambodia eVisa is still approved in 3 business days; the calendar around those three days simply expands when a holiday lands inside your processing window.
Australian travellers tend to plan Cambodia trips around two reference points: the school-term calendar back home, and a public-holiday weekend like Anzac Day or the Melbourne Cup long weekend. What most Aussies don't think to check is the Cambodian public-holiday calendar — which runs on completely different dates, includes three-day religious and royal observances, and closes MFAIC's eVisa processing unit completely for the duration. A trip planned for the Anzac Day long weekend, applied for two weeks beforehand, can end up running headfirst into Khmer New Year. The eVisa promise of 3 business days still holds; those three business days simply don't include any of 14, 15, or 16 April.
The good news: Cambodia's holiday calendar is published months in advance and the patterns are remarkably stable. The 2026 calendar is already locked, the major dates haven't moved in years, and once you know which weeks to avoid you can plan around them with confidence. The bad news for some Aussies: Khmer New Year falls right when Anzac Day travel demand peaks, and the early-November holiday cluster overlaps Melbourne Cup week. This guide walks the full 2026 calendar, with the Aussie-specific timing buffer for each holiday block.
If you have not started yet, the apply page accounts for the major holiday windows in its delivery estimate. The cost of an early submission to absorb a holiday block is exactly zero — Cambodia eVisa pricing doesn't change based on when in the year you apply, and the $80 USD (~$122 AUD) tourist all-in is identical in April and August. For the canonical reference on cost, documents, and processing, see the Cambodia visa application for Australians hub.
Cambodia gazettes around 22 public holidays each year, but only the ones that close MFAIC's processing office matter for eVisa timing. The list below covers every closure that materially extends the 3-business-day clock in 2026. Single-day closures are listed where they fall on a weekday — Saturday or Sunday closures are absorbed by the existing weekend rule and don't add additional delay.

Four nights Siem Reap for the temples, three for the harder history of Phnom Penh, three for the slow river days of Kampot, three for the warm water of Koh Rong, one buffer night for the day you wish you had. Here is the honest 14-day Cambodia plan for Aussies in 2026 — costs in AUD, transport in plain English, eVisa timing baked in.
The 12-month Business eVisa extension is the longest commitment-level Cambodia stay Aussies can buy in-country. ~$300–400 USD (~$457–609 AUD) through a Phnom Penh agent on top of the $90 USD (~$137 AUD) Business eVisa, 7–14 business days. Best per-month rate of any extension — but only worth it if you genuinely plan to use the back half of the year.
Three nights in Siem Reap for Angkor, three nights in Phnom Penh for the riverfront and the harder history, one buffer night for the day you wish you had. Here is the honest 7-day Cambodia plan for Aussies in 2026 — costs in AUD, transport in plain English, and the eVisa timing baked in.
Christmas is normal business in Cambodia
Cambodia does not observe 25 December as a public holiday. MFAIC processes eVisas normally through Christmas Day and Boxing Day. Aussies booking a Boxing Day flight to KTI Phnom Penh can apply right through the festive period with no holiday lag.
This is the single most important holiday window for Australian Cambodia travellers in 2026, and most Aussies don't see it coming. Anzac Day falls on Saturday 25 April 2026, making the long weekend run from Friday 24 April to Monday 27 April for most states. School holidays in NSW and Victoria run roughly 4 April to 19 April. A natural booking pattern is: fly out the first weekend of school holidays (4–5 April), spend two weeks in Cambodia, return for the Anzac Day weekend. Apply for the eVisa two weeks before departure — late March.
That works fine. The trap is the second pattern: fly out for the Anzac Day long weekend itself, around 23–25 April. Apply two weeks before — early April. Now your application sits with MFAIC right as Khmer New Year approaches. Submit on Friday 10 April and the file enters the queue with one working day left before the holiday block. Days are skipped 14, 15, and 16 April. The weekend of 11–12 April is also skipped. Processing resumes Monday 20 April. Your three-business-day clock now has officers reviewing day one on 13 April briefly, then resuming on 20 April for days two and three — approval lands Wednesday 22 April. Cutting it fine for a Friday 24 April flight.
Sienna, a Melbourne primary teacher, books her Phnom Penh flight for Saturday 25 April 2026 to use the Anzac long weekend plus accumulated leave. She plans to apply for the eVisa two weeks ahead, on Saturday 11 April. Sienna doesn't realise Khmer New Year starts Tuesday 14 April. Saturday 11 April: portal accepts the submission, but officers don't see it until Monday 13 April. Day one runs Monday 13 April. Tuesday 14 April: Khmer New Year, office closed. Wednesday 15 April: closed. Thursday 16 April: closed. Friday 17 April: officers return, but day two doesn't start until then. Day two Friday 17 April, day three Monday 20 April — PDF arrives Monday evening Phnom Penh, Tuesday morning Melbourne. Sienna's flight is Saturday 25 April. Five-day buffer. Fine, but she didn't realise how close she came.
The fix is straightforward: for any Anzac Day or late-April departure to Cambodia, apply by 1 April — two weeks before Khmer New Year starts. That gives officers a full clean working week to process before the holiday block. The when-to-apply article maps flight distance to submission day across the full year, with the Khmer New Year buffer baked in.
After Khmer New Year, the next consequential window for Aussie applicants is Queen Mother's Birthday on Thursday 18 June 2026. This is a single-day royal observance — MFAIC closed just for the one day — but it lands on a Thursday, which means officers close Thursday and resume Friday for a single day before the weekend hits. Practical effect: a Wednesday 17 June submission gets day one on Wednesday, then skips Thursday, then resumes Friday for day two, then the weekend, then Monday 22 June for day three. Five calendar days from Wednesday submit to Monday PDF — not catastrophic, but worth knowing.
King's Birthday in May is a three-day royal block — 13, 14, and 15 May 2026. Three consecutive working days closed (Wednesday through Friday) plus the surrounding weekend equals five calendar days where the clock is paused. For Aussies travelling around the Queen's Birthday long weekend back home (8 June 2026 in most states, 1 June in Queensland), this matters because the booking-to-submission gap can easily intersect. Apply by late April for a Queen's-Birthday-week departure.
Constitution Day on Thursday 24 September 2026 is a single-day closure that lands inconveniently mid-week. A Wednesday submit gets one working day before the office closes Thursday, resumes Friday, weekends, then Monday for day three. The pattern is the same shape as Queen Mother's Birthday — one day extends a normal three-business-day cycle to roughly five calendar days. Aussie travellers using September school holidays should aim to submit by 8–9 September for a late-September departure.
The single-day closure pattern
A single Cambodian holiday landing mid-week typically extends your processing window by one to two calendar days, depending on which weekday it lands on. Compound it with the weekend rule for the practical Aussie impact.
Cambodia's busiest public-holiday quarter is October and November, and it matters because it overlaps Melbourne Cup week and the Aussie school holiday window in September–October. Four separate blocks land within six weeks. The cumulative effect is that any Cambodia trip planned for late October through mid-November needs the holiday calendar pinned to the fridge.
Pchum Ben is the Cambodian Ancestors' Day, observed across three working days — Tuesday, Wednesday, and Thursday 20–22 October 2026. MFAIC closes for the full block. Combined with the preceding weekend and the following one, processing pauses for nine calendar days from Saturday 17 October through Sunday 25 October. For Aussies travelling in Term 4 school holidays, apply by 1 October for any late-October departure.
Eight days after Pchum Ben ends, the King's Birthday royal block opens — Friday 30 October, Saturday 31 October, and Sunday 1 November. Effective MFAIC closure runs Friday through Sunday, with normal processing resuming Monday 2 November. Aussies booking around the Melbourne Cup long weekend (3 November in Victoria) should be aware the eVisa office is closed all of the preceding Friday and weekend.
Independence Day lands on Monday 9 November 2026. Combined with the weekend, MFAIC is closed from Saturday 7 November through Monday 9 November — three calendar days. Single-day Monday closures are the cleanest holiday pattern from an Aussie applicant perspective because they only extend the weekend rule by one working day. A Thursday or Friday submit the week before goes through normally.
Water Festival is the second of Cambodia's two three-day religious blocks, running Monday, Tuesday, and Wednesday 23–25 November 2026. MFAIC closes the full block. Combined with the preceding weekend, processing pauses for five consecutive calendar days. Aussies travelling for late-November or early-December bookings should apply by 5 November for any departure between 25 November and 5 December.
The companion weekend-rule article walks the standard three-business-day clock without holidays in the window, useful for understanding the baseline. The Friday-application-timing article covers the worst-case submission day patterns.
Aussies booking a Boxing Day or January departure for a Cambodia trip have a quiet advantage: Cambodia does not observe Christmas as a public holiday. 25 December is a normal Thursday working day at MFAIC's processing office. 26 December — Boxing Day in Australia — is also normal business in Phnom Penh. Officers process applications through the entire western festive period with no closure.
The single closure to watch in this window is International New Year on 1 January, observed in 2026 as a Thursday — MFAIC closed for the one day, combined with the weekend creating a four-day pause from Thursday 1 January through Sunday 4 January. Beyond that, Victory over Genocide Day on Wednesday 7 January 2026 is a single-day closure mid-week. Both are well-flagged on the Cambodian government calendar.
Practical effect for Aussies: a Boxing Day flight from Sydney to KTI Phnom Penh works smoothly with a mid-December eVisa submission. A New Year's Eve flight requires applying by mid-December to absorb the early-January closure cleanly. A 7 January departure can apply on 30 or 31 December and still beat the 7 January single-day closure.

Compare the two →If you take one heuristic from this article, make it the 14-day rule for major Cambodian holiday windows. The 3-business-day approval promise still holds inside any working week — but if your trip falls within two weeks of Khmer New Year, Pchum Ben, or Water Festival, apply 14 days ahead regardless of how comfortable the regular math looks. The cost of an early submission is zero. The cost of a late submission inside a holiday block can be your entire trip.
The Aussie-timezone support promise
