How fascinating. Some of those are completely different from the stereotypes they'd be assigned in the US, Sundae. For example:
"Australian" - Okay, I can see this one, though my initial thought would have been more along the lines of "beach volleyball player" rather than the nationality.
"Ghetto Ho" - given
"Transvestite Artist" - transvestite yes, but definitely not artist. Would have said low-level customer service rep, as dismally unhappy with her job as she is with her gender.
"Farmer" - Ooh, way off for me. Childless aging hippie. Maybe an artist, or a midwife, or a juice bar owner.
"Mum" - Redneck white trash. Probably is indeed a "mum" in the sense that she has offspring, but not the average overtired stay-at-home mother image you are seeing. This one slaps them around when they start misbehaving towards the end of her shift at WalMart.
"Halfwit" - Heh. She's a tourist. Which may very well equate to halfwit after all...
"Transvestite with Grandchildren" - Except her own children and grandchildren shun her, so she toddles about in the grocery store stopping every random woman with young children to irritatingly fawn over them as a substitute.
"Junkie" - a junkie's a junkie, the world 'round.
