Lovely friend, Stuart McDonald - film director based in Melbourne gave me this link of a series he recently worked on.
I think you need to understand the Australian paradigm to enjoy it - I watched it on my ipod last night in bed and thought it was hilarious... (would be interested to see what my friends from elsewhere think of it). Requires a strong handle of fairly unsophisticated coarse English language.
The main three characters (Ja'mie a snobby grade 11 girl, the ambitious gay drama teacher - Mr G and Jonah, a year 8 polynesian boy) are all played by Chris Lilley, the writer and associate producer.
