I got my email 1 month before my expected arrival period (which makes sense, as my insurance broker told me that quotes are usually valid for only 1 month)Yeah I'm debating registering as a 2024 model as that's when it will be registered (and it's cheaper). I haven't received the "Your car is an MY23.5" email that some people on here have had.
Here is the extract from mine for reference, the email is pretty generic, so I'll assume it would be the same between Melbourne and Perth
