Well, here's some nice language examples, all Australian and from June 2017 onwards

Aussie language:
- "I was just at Dave’s house relaxing, chilling out having a beer and in through the door, crikey it’s Ringo so I said ‘G’day mate how’s it going’" - Australian musician Jon Stevens, June 2017 - reflecting his Australian identity with lots of Aussie colloquialisms (crikey, g'day, mate), [link]
- "That is the duck's nuts of being a pop", "mate", "meself", "I'm stuck on a bloody island", "uru" - all said by Queenslander Mark H on Australian Survivor, episodes aired late July and early August 2017 - again, Australian identity being reflecting with lots of Aussie words and phrases
Younger speaker's language:
- "maybe you just minestrone-d the gas" - Hamish Blake, August 2017, talking about how his recent meal of minestrone soup flavoured the gas for his pregnant wife - could be related to language play or young people converting words more readily than older speakers (so language variation with age)
Jargon:
- “Cytotoxin”, “diazonamide”, “microtubule” - all terms used by scientist Patrick Harran on ABC Radio National’s Science Show, July 2017 - jargon being used to communicate effectively, also could be to include/exclude listeners, [link]
- "The text generally does an exceptional job of describing the essence of a species in a concise and accessible way, only rarely sliding into alienating scientific jargon. (Why use "obligate frugivore" to describe a superb fruit-dove when "fruit eater" would have sufficed?)" - a quote from a July 2017 Sydney Morning Herald article about a new birdbook - about how bird-related jargon can exclude readers that aren't familiar with the terms, [link]
- "Education Minister Simon Birmingham recently used the obfuscating jargon “efficiency levy” to describe unpopular university funding cuts." - a quote from a June 2017 article about Aussie politicians and jargon, lots of other good quotes in the article too - about how jargon can be used to obfuscate and obscure the truth, [link]
