A few random English language things from here and across North Australia:
TI Utes: dinghy (in the Torres Strait; TI = either Thursday Island or Torres [Strait] Islander depending on where you are)
f belong mother: you can work this one out
charge up: to get drunk; also charged up. I have a feeling that this is more widespread than Kimberley English.
toilet-paper dog: a bit darker than the average colour of a dingo.
And a few things which are more widespread (ie, Standard Colloquiual Australian English) but which I hadn’t heard for ages.
tragic as a noun as well as an adjective, as in “He’s a real Dockers tragic”.
–est is completely productive as a superlative formative. My favourite was ‘he’s the gaarijoonest bloke’ (gaarijoon = Bardi for ‘drunk’)
I’m confirmed in my opinion that coda l vocalisation is not in the least a South-Australian isogloss (you’ll hear this in Australian linguistics: South Australians vocalise their coda ls and say poow for pool). It’s all over the place.
