Aussie consultants flying to Cambodia 4-8 times a year on short engagements: five single-entry Business eVisas costs $450 USD (~$686 AUD); one 12-month multi-entry costs roughly $200 USD (~$305 AUD). Plus four fewer applications. Here's when the maths makes it obvious.

At four trips a year and above, comfortably. At five trips a year, the maths is brutal — five single-entry Business eVisas at $90 USD each is $450 USD (~$686 AUD), versus the 12-month multi-entry Business eVisa at roughly $200 USD (~$305 AUD) all-in. That's a $250 USD (~$381 AUD) saving on cost alone, plus the time saving of four fewer applications and four fewer 3-business-day waits. Below four trips a year, the maths gets closer: at three trips it's $270 USD (~$411 AUD) in single-entry fees versus $200 USD multi-entry — multi-entry still wins, but more narrowly. At two trips, $180 USD (~$274 AUD) in single-entry fees beats multi-entry. The pivot point is honestly four trips a year for Aussie consultants on short engagements, with each individual stay under 30 days.
This guide is the cost arithmetic and calendar-shape walk-through for Aussie consultants on the four-to-eight-trips-a-year cadence. The Cambodia multi-entry Business eVisa rules guide for Australians has the underlying rulebook, and the Cambodia eVisa application page is where the multi-entry option lives at checkout.

Above four trips, the maths stops being interesting and starts being obvious. Five trips at $450 USD (~$686 AUD) versus $200 USD (~$305 AUD) is a $250 USD saving with zero downside in the typical consultant trip-shape. Six trips is $340 USD saved, eight is $520 USD saved. For the average Aussie consultant on a year-long regional engagement, the multi-entry path is the only sensible answer. The Cambodia Business visa for Australians guide covers the underlying product if you haven't yet bought a Business eVisa.

The quieter but real benefit is the elimination of week-of-departure visa stress. On the single-entry path, every Cambodia trip needs you to apply at least 4-5 business days before departure to clear the 3-business-day processing window with a safety buffer. Forget once, lodge two days before the flight, and you're staring at a missed trip or a fallback to Visa on Arrival. The multi-entry path makes that worry vanish — your visa is in place for the full 12 months, ready for any trip that lands in the calendar with two days notice or two months notice. For consultants whose client work shifts week to week, that's a category of risk that simply stops existing. The Cambodia evisa processing time guide for Australians covers the standard 3-business-day window in detail.

Scenario D — Aussie consultant with one long stay in the year (say, 45 days for a project kick-off) followed by short return visits. Multi-entry is structurally the wrong product for the opening 45-day stay. You'd want a single-entry Business eVisa plus an in-country extension for the opening block, then potentially a fresh multi-entry application for the rest of the year. The Cambodia Business visa extensions guide for Australians has the long-stay mechanics in full.

Pattern three — Cambodia trips alongside more frequent trips to a country with its own visa requirements. If your engagement is genuinely regional and you're also doing eight Vietnam trips, six Indonesia trips, and four Cambodia trips a year, the headline question shifts from "single vs multi-entry Cambodia" to "how do I rationalise my regional visa stack". The Cambodia frequent-traveller visa strategy guide for Australians is the right anchor for the broader question; multi-entry on Cambodia specifically is still the right call inside that picture.

At five trips it's $250 USD saved; at eight it's $520 USD saved. Plus the application time saving across the year. Plus the elimination of week-of-departure visa stress. The Cambodia visa cost guide for Australians has the line-by-line pricing across every class.
Caveats — if any single trip in the year will run past 30 days, multi-entry is the wrong product and you need a Business eVisa plus an in-country extension instead. And if your year shape is genuinely one or two Cambodia trips on a leisure rather than business purpose, the Tourist eVisa at $80 USD (~$122 AUD) per trip is still the right product. Otherwise, the multi-entry option lives at checkout on the standard Business eVisa application — 3 business days, printable PDF by email, free resubmission if Immigration flags a correction, Aussie-timezone support across any resubmission.
