So if you did want to become an Australian down the track, you would have to relinquish some of your existing citizenship's. For example, I am a permanent resident of Australia and a citizen of NZ and the UK (have NZ and UK passports). If I wished to become an Australian citizen (never seen the point in my case), I'd have to give up either the NZ or UK passport.
I think you have been misinformed - there are several that hold AUS/NZ and UK citizenships (and passports) legally. Australia allow multi citizenship, but it is generally referred to as dual citizenship. Australia does not require any renouncement of citizenship for any country even if the other country is a single citizenship only country.
