I feel I have a national obligation to start this thread, following the three threads for other regions: • Are-there-any-americanisms-in-lyrics-that-we-can-explain-to-you-non-americans. • Are-there-any-britishisms-in-lyrics-that-we-can-explain-to-you-non-brits. • Are-there-philly-isms-that-we-can-explain-for-youse-guys-not-from-philly. I'm not taking responsibility to answer all questions, my fellow country men and women can help! I will start with what is often considered to be the national food of Australia: Vegemite. As popularised by Men at Work in their hit "Downunder", it is indeed a popular sandwich filling. Black, thick, with the primary ingredient being salt. It was developed by Cyril Percy Callister in Melbourne, Victoria in 1922, as a way of disposing of excess used yeast being dumped by breweries. Most foreigners don't like it because they put it on bread/toast too thickly. It's horrible like that. It should be smeared very, very thinly. I still think it's horrible, but it's less horrible when eaten in moderation. And please don't expect Austen Tayshus' "Australiana" to be explained in one post!
