My relatives in australia speak english and a bit of german. They told me they had the choice to learn german or spanish in school.
But what is the point, other than you really want to learn a random language? I learned french, then english and later i had the opportunity to learn italian or spanish if i wanted to. But that's because these are the languages people speak here and the bordering countries. My relatives never used any of their german, except when they went to europe once.
