@leonp Thanks for the vocab list! It's interesting, and good to see I got many things right 😊
As far as the accents go, I'm not sure about the Australian accent having any strong connection to the Suffolk one, particularly. The first Australian English speakers were the children of the (mostly) convicts around Sydney Harbour, who were mostly from southeast England but particularly from London, as you might expect. (There were also plenty of Irish convicts, but they didn't make much impact on the accent – I've read a theory that it's because they were mostly second-language speakers of English at that time, but idk really.) I did just look up a video of a Suffolk accent and did notice some similarities, though, especially in the PRICE vowel (this guy, at least, alternates between the [ɛɪ] and [æɪ] vowels for it) and the strong pronunciation of schwa as [ɐ] at the ends of words. So similarities, yes, but I don't think the Aus accent is "descended" from the Suffolk one, it's more likely a convergent development :)
