Thanks, Carrol. I'm British, so lucky enough to have cultural access to at least some of the vibrant world of Aussie slang. You're right about the Americans, though. It's hard to know which phrases and cultural references have become universally familiar - I would have added a link, were it not for Medium's 30-second rule. If you include a hyperlink in the opening couple of paras of a story, you run the risk of people clicking on it before they have read for 30s, which halves your read ratio and kills distribution and earnings. It's a perverse decision by the platform which works to the detriment of both writers and readers, unfortunately.
