This isn't really a specific example but I would suggest that the class of 2017 spend their holidays watching Australian TV shows instead of American ones to prepare ahead for language and identity- (be open minded when writing essays, some Unit 4 examples work just as well in Unit 3 essays)
e.g.:
Upper Middle Bogan for class differences in Australian English (yes, there are actually some class differences even though we're egalitarian and stuff),
Utopia for corporate jargon, look for doublespeak and attempts to establish expertise
Black Comedy- Aboriginal English
Superwog (Youtuber)- ethnolects, generational and gender differences, take note of how he changes his accent for Australian dad vs Australian mum vs Australian kid vs "wog" kid (2nd generation migrants) vs "wog" dad (1st generation migrants), you may want to use the IPA to talk about certain sounds in your essays
Watch the ads on TV- how do certain brands use language to create their identity?
Also keep your eyes out just encountering language everyday, remember that the news isn't your only source of examples, have a look at essays in the examiner's report for ideas
Good luck for English Language
