Lol...we're renowned for it I think. It's funny, when I travel overseas I usually say a lot more Australianisms...I think. I mean, maybe it's just that I'm just more focused on how many of that I say day to day because no one else is saying the same.
When next you see your friend, and she shows you something you like or that is good say, "crikey, that's bonza!"
Brilliant! I'll have to make a video
Please do!
