Thank you for your help [MENTION=4346]moondog[/MENTION] So I’m assuming on the system that the airline will use, these exemptions are listed in more detail than what the publicly accessible IATA “check” does? Because that does not talk about any exemptions at all and I don’t think any screengrabs from the internet will help me.

I’d hope that in any case I’m not the only one in Australia who’s a dual citizen from one of these countries so at last some supervisor would have had this situation before. Just don’t quite trust them- I would have zero fears if I was checking in with proper SQ agents in Changi.
