Remote area nurse Gayle Woodford was raped and murdered by Dudley Davey in March last year after being lured away from her Fregon home, in South Australia's north, late at night.
Davey has been jailed for at least 32 years for his crimes with a judge describing his offending as "callous in the extreme".
Ms Woodford's husband Keith Woodford says he hopes the 35-year-old is never released and dies in jail.
He says he plans to devote the rest of his life to supporting the welfare of all nurses working in regional and remote areas.
He will campaign for the introduction of legislation to ensure nurses and other health professionals no longer have to work alone, something that has been dubbed Gayle's Law.

"I will do whatever is necessary to apply public pressure on governments, health authorities to implement Gayle's Law," he said.
"We must act to adequately protect nurses and medical staff in remote areas to ensure the crime that took Gayle away from us will never be allowed to happen again."
Mrs Woodford had lived and worked in Fregon for five years, and community leaders say her death has cast a "dark cloud" over the state's indigenous lands.
They say Davey will never be welcome to "return to country".
