Chasing the Irrawaddy dolphins and the Si Phan Don river-island circuit on a Cambodia Business eVisa? This is the Tropaeng Kreal-Veun Kham loop for Aussies — slower than Bavet, much quieter, and the natural pairing with a wildlife or Mekong-river trip.

Treat each Cambodia entry as a separate single-entry Business eVisa: $90 USD (~$137 AUD) all-in, approved in 3 business days, delivered as a printable PDF by email. Pair it with Laos visa-on-arrival ($35 USD (~$53 AUD) for Aussies in cash) at Veun Kham, since Laos still issues VoA reliably to Australian passport holders. The slow rhythm is fly into Phnom Penh KTI, head north via Kratie and Stung Treng for the Mekong dolphin and dry-forest segments, cross at Tropaeng Kreal-Veun Kham for the Si Phan Don river-island and southern Laos circuit, then file a fresh Cambodia application from Pakse and re-enter overland three or four days later. The crossing itself is slower and quieter than Bavet — perfect for an Aussie wildlife or Mekong trip combo.

Tourist or Business eVisa for the wildlife loop?
If your trip is genuinely tourism — wildlife, photography, river-islands, no paid work, no meetings, no conference attendance — the Tourist eVisa at $80 USD (~$122 AUD) is the right choice. Business at $90 USD (~$137 AUD) is for engagements involving paid work, supplier visits, sales calls, due-diligence, sponsored events, or longer working stays. Most Aussie Mekong wildlife trips fit cleanly under Tourist, which makes the per-loop visa stack closer to $200 USD (~$305 AUD) all-in.

USD cash, clean small notes
Tropaeng Kreal and Veun Kham have no ATMs. The Lao VoA fee must be paid in cash — bring $40 USD (~$61 AUD) per person in clean small notes (no tears, no ink marks, no notes older than 2013) to cover the $35 VoA plus any informal small surcharge. The nearest reliable ATM is Stung Treng on the Cambodian side or Pakse on the Lao side, both at least 90 minutes away from the booth. Do not rely on the money-changers at the border; their rates are roughly 12% below market.
