Australia gave the world preferential voting, and WiFi. And the Peach Melba.
EDIT: And a great many innovations in farming, solar power, irrigation, and salinity management. Also, the cochlear implant, spray-on artificial skin, the notepad, the electronic pacemaker, the refrigerator, the electric drill, the black box flight recorder, and lots more [http://en.wikipedia.org/wiki/List_of_Australian_inventions]. We have been busy, haven't we?
According to wikipedia, Australia even made the world's first powered manned flight in 1894, nearly a decade before the Wright brothers.
Quite simply, we rock.
