Lost contact with a friend from Canberra, Australia?

I'm having problems finding contacts of this boy I met on a Beijing Tour in January 2003. I'm struggling really hard because the only details I have is his name (Michael), where he's from (Canberra, Australia) and that he's cantonese. I also have 2 photos of him but that doesn't help because I can't exactly scan the photo and google that. I don't even know where to start because I don't know his surname, please someone help. :(
