Linguists.........help me!

Bah, you speak that bastardised dialect known as "Australian English".

Have you heard me speak?

The milder form of the accent (such as I have), is, yes. But the extreme part-cockney, part-carribean, part-asian, part-chav farrago that constitutes the most abect extremes of Estuary carry with them social disdain that was once the preserve of extreme northern or cockney accents.

That isn't Estuary English then. That's just local weird accents.
