Upper Middle Bogon (is based in Australia!!!)
American Horror Story
Orange is the New Black
And I don't know if this is available on non-Aussie Netflix's but. BUT.
Here are some Aussie shows!
Round the Twist
The Umbilical Brothers (I've heard it's good but no promises)
H2O - Just Add Water (only if you're into shows aimed at children to young adults. Personally this show just pisses me off, but most other people who are not me seem to enjoy it)

Well, I'm not sure if all of these are on Netfix but...
Mr Robot is highly rated too, as is The Walking Dead. I've not watched much of either yet.
