A Queensland doctor who helped develop a vaccine against cervical cancer has been named the 2006 Australian of the Year.
Ian Frazer has spent the last 20 years working on a vaccine to combat the sexually-transmitted human papilloma virus (HPV), which causes more than two-thirds of cervical cancer cases.
There are half a million new diagnoses of the cancer recorded each year, including around 800 in Australia.
Born and raised in Scotland, Professor Frazer came to Australia in the early 1980s and went on to found the University of Queensland's Centre for Immunology and Cancer Research.
He follows the 2005 winner of the award, Fiona Wood, who shot to fame in 2002 for using her spray on skin to treat burns victims of the Bali bombings.
Whistleblower nurse Toni Hoffman, who saved countless lives by exposing the now-notorious "Dr Death" in 2004, is Australia's Local Hero in 2006.
Two years ago, Ms Hoffman blew the whistle on Dr Jayant Patel's work at the Bundaberg Base Hospital in south-east Queensland.
An inquiry into the matter unearthed a trail of horror stories, including bloody deaths on the operating table, limbs left unchecked until gangrenous, punctured bowels and spleens and the removal of wrong body organs.
In two years, Dr Patel is thought to have been responsible for at least 80 patient deaths.
