There’s a learning curve here in Australia. Some words and phrases have to be sorted out.

“Brelly” refers to an umbrella, which luckily we haven’t needed yet, as the weather has been crystal clear.

“Brekky” was, in context, pretty clearly a reference to breakfast.

Then there are a couple of phrases we’ve heard.

“Don’t be a porkchop,” one conference participant said in an informal conversation.

We had to look that one up.

From a website of Australia National University:

pork chop: to carry on like a pork chop

To behave foolishly, to make a fuss, to complain, or to rant. This expression is often thought to allude to the spluttering noise of a pork chop that is being fried. However it is probably a variant of the older expression like a pork chop in a synagogue, meaning something that is unpopular, unlikely, or rare (with reference to the Jewish prohibition of the eating of pork). To carry on like a pork chop is first recorded in 1975.

2002 Sunday Telegraph (Sydney) 10 November: The Australian sports public are a forgiving lot. Ask Lleyton Hewitt. Or Shane Warne. Here are a couple of champions who, on several occasions, have carried on like pork chops.

2003 E. Vercoe Keep Your Hair On: She’s a beautiful woman, your mother, but by God can she carry on like a pork chop about nothing.

And then our favorite, “never drop your bundle.”

Turns out it means something like “stay cool,” or “cool head.”
