This is the word I usually use when asked for an example of a word that is different in Australia. What we would call a comforter or a duvet in Canada, the Aussies call a Doona, and I have no idea why. Maybe the word is a bastardization of duvet? Anyway, it’s different enough to make people realize that yes, Australian English is a lot different than Canadian. It was a weird one for me at first, but I’ve gotten used to it. I’m definitely ready to fight back when my partner tells me I’m hogging all the doona.
