Former Australian IMO Team Members

Register of Former Australian Mathematics Olympians

Australia's participation in the International Mathematical Olympiad is directed by the Australian Mathematical Olympiad Committee, a subtrust of the Australian Mathematics Trust. Any information on whereabouts of the Olympians below would be appreciated and can be directed to Peter Taylor. It is suggested at least degrees (inc University) awarded, years, and current activity would be of interest at a minimum. Anyone who has a home page which they would like to hot-link, please advise your URL. Finally if anyone has any old photos we are looking for some to add to this page. They can be sent to Peter Taylor and if hard copy you will definitely get them back!
