Know anyone?

At last, a chance at the big(ish) time. I've been commissioned to write an article for a newspaper magazine liftout. But I need contacts, which is where this plea comes in. The story is on Australian expats who return from overseas, and what they think of Australia now. All I need is a nice mix of Sydneysiders and Melburnians who've gone overseas for career purposes and I can do the rest. Do any celebrities, minor or major, spring to mind? I'm terrible at knowing who's who. Or anyone you know with interesting stories to tell. I know this is shameless, but please help. Deposit spare contacts in the comment box provided. Otherwise, I'll starve. I love you all.
