All I can remember of the grammar at the moment is;
* The use of 'me' instead of 'my' (Me mates dropped 'round to visit)
* The used of 'come' instead of 'came' (Me daughter-in-law come up from Melbourne last week)
* And occasionally the use of 'the' in front of new technology (I'll have to check the email to see if there's a message from her)
Lexically I can remember a lot more, but I'd LOVE to hear any other words or phrases that anyone else has got.
* Using the word 'tea' instead of 'dinner' (side note: I still do this, and I still get looked at strangely and mocked for doing so.)
* As useful as tits on a bull (completely useless)
* Going arse over tit (falling down, messing up)
* Heading into 'town' (where 'town' is the next biggest locality to the one you're currently in.)
* Duffer, silly duffer (a fool)
* Knocked off (stolen)
* Carrying on like a two-bob watch (making a big noise and fuss)
* Wireless (the radio)
* Six of one, half a dozen of the other
* You can spit in one hand and want in the other and see which you get first.
I'd love to hear anyone else's Rural Australian colloquialisms.
ETA I don't know when it came into common use but "arc up" (to get angry) is also now on my list.
