Sydney/Melbourne to Cambodia via Changi or BKK works smoothly on the eVisa-only flow — your stopover does not change your visa requirements. The trick is the e-Arrival window (7 days before Cambodia arrival, not Australian departure) and what you actually do with a 12-hour Singapore vs 18-hour Bangkok layover.

No — your stopover routing does not change the Cambodia visa rules. The Cambodia eVisa is issued on the passport you hold, and Australian passport holders get the same $80 USD (~$122 AUD) all-in Tourist eVisa regardless of whether you fly direct, stop in Singapore (Changi), Bangkok (BKK Suvarnabhumi or DMK Don Mueang), Kuala Lumpur, Hong Kong, or anywhere else. Approved in 3 business days, delivered as a printable PDF by email, valid for 3 months from issue, single entry, 30-day stay. The one detail that does shift with a stopover is the e-Arrival Card — its 7-day window counts back from your Cambodia arrival date, not your Australian departure date. If your trip starts with a 2-3 night Singapore stay, you fill the e-Arrival from your Singapore hotel during that stop.
Visa-free transit in Singapore and Thailand
If you are only transiting airside (staying in the secure transit area without clearing immigration into Singapore or Thailand), neither country needs a separate visa from you. If you leave the airport for a stopover, Australian passport holders are visa-free in Singapore for up to 90 days and in Thailand for up to 60 days — no separate eVisa required for the stopover country itself.
