Symbol Search

After my day in China-town the thought of cultural symbols stayed with me. I'm looking for an equivalent to the "auspicious" symbols of Chinese culture. Obviously in a different culture like ours, even the way symbols work in different, but nevertheless it's worth some thought.

Just to make things harder I decided to exclude obvious commercial symbols--MacDonalds and Coke are both out--and I don't think the classic Christian symbols are universal in Australian culture in general. So, suggestions please!
