The first was carpenter Bob Dent, 66, who died on 22 September 1996. Dent was a prostate cancer sufferer who became Australia's first person to lawfully end his life by means of physician assisted suicide. Dent, who had been suffering from prostate cancer for five years in what he called "a rollercoaster of pain", left an open letter when he died that stated: "If I were to keep a pet animal in the same condition I am in, I would be prosecuted. If you disagree with voluntary euthanasia, then don't use it, but don't deny the right to me to use it." He died with the help of Dr Philip Nitschke.
