Jim C- you're dead right about the terminology, but I'll have one more go- it's good to agree with you about SOMETHING anyway!!
Ignorance of anything outside England (or part of it?) has been well demonstrated for many years & especially today
When we did B&B in West Cork, we had English visitors who brought their own stamps for their postcards. And quite annoyed to be told they'd need to buy Irish ones!- how long has Ireland been independent?

Originator of the thread hasn't clarified what he/she really wants and Aussies are probably better probably better informed, but hopefully someone can give more specific advice to make the best of the trip...
