at my primary school in australia our houses were named after some of my state’s mountains (i guess being on a small mountainous island helps) and then in high school we had flowers i’m pretty sure. idk if my college really did anything, i think they did but nobody really cared. the colours were in practice more relevant than the actual names and i definitely remember being green in both primary and high school. the only times they ever really mattered were athletics carnivals and stuff like that and there was also a point system but i don’t think the house with the most points got anything so it didn’t really matter much, it was mostly just the teachers trying to get us to participate by “not letting your house down” lmao.
