What a great shock it was to hear of Roy's sudden passing. It was my privilege to act as Roy's academic supervisor at Sydney Uni. In that time Roy was not only my student, but also my friend and occasional golf partner. I will forever remember his enthusiasm for life, and his passion for his scientific studies into aspects of the biology of endangered species. The planet needed Roy, and we all needed Roy. My thoughts are with Roy's family. Unfortunately I will not be able to attend the memorial service.
