I hate it when a non-Australian tries to do an Australian accent. It's so grating and it's not even close - it always sounds like a cockney New Zealander.
That should have been cockney South African. I don't know what made me think of New Zealand. Maybe my earlier comment about Maori/Polynesian/Islander accents had me fantasizing about taking a holiday in the South Pacific.....
.....or Bondi.
