the wording specific to Australia [closed]

While chuck has the usual meaning of "throw", it's often used in Australian English in the sense of carrying out an action (chuck a uey = "make a U-turn") or putting on a performance (chuck a mental = "throw a wobbly" = lose self-control).

chuck a sickie

A day's sick leave, especially as taken without sufficient medical reason. Sickie is an abbreviation of the term sick leave, and illustrates a distinctive feature of Australian English — the addition of -ie or -y to abbreviated words or phrases. Other examples include: firie ‘firefighter’, surfie ‘surfer’, and Tassie ‘Tasmania’. Sickie is first recorded in 1953, and is often found in the phrase to chuck a sickie, meaning ‘to take a day’s sick leave from work’ (often with the implication that the person is not really ill).

• 2003 Canberra Times 21 June: The age old practice of ‘chucking a sickie’ in the Australian Public Service is costing the taxpayer at least $295 million a year.

The injunction "stop carrying on like a pork chop" is typically heard from an exasperated parent when an overtired child puts on a performance because they didn't get what they wanted.

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.
