Fastirs – Ustrelyin Fa Bier - further excercises in language

While in Sydney I’m trying to conquer the rules of how they talk. I think I’m starting to get it but I’m still trying to get all the various changes down:
The double ee sound (sometimes the ea) becomes more like an ie. So beer sounds like bee-er.
The long a sound (like day) is pronounced like a long I (like eye). So day sounds like “die”.
Ah’s become like eh’s. And er’s become like ir’s. So “faster” sounds like “festir”. And better sounds like bittir.
O’s sounds like a’s, so Fosters sounds like “Fastirs”. And Australian sounds like Ustrelyin.
And so now, I finally understand what that guy on the Foster’s commercials was saying! Too bad they don’t sell Foster’s in any reputable bar here . . .No worries, mate!
