Professor David Goldstein is a medical oncologist at Prince of Wales Hospital who worked on the GIST protocol in 2004 in London. Prof. Goldstein would have the bulk of GIST patients in Eastern Australia I think, but there is also a lot of work going on at the Peter Mac Institute in Victoria.
Professor Philip Crowe is a surgeon who does some very difficult and protracted surgery at Prince of Wales Hospital.
