Melbourne park killer's jail term appeal

A man who raped and murdered budding comedian Eurydice Dixon at an inner-Melbourne park is appealing his life jail sentence.

Jaymes Todd was imprisoned for at least 35 years before being able to apply for parole, after pleading guilty to attacking the 22-year-old as she walked home through Carlton North in June 2018.

Paperwork was filed in court earlier this week and news of the appeal became public on Thursday, confirmed by Todd's former lawyer Tim Marsh.

"There is an application to challenge that (sentence)," he told the Victorian Supreme Court on Thursday during a different case.

Todd stalked Ms Dixon for more than an hour and attacked as she walked through Princes Park after a comedy gig.

"Your actions in doing so were of pure and unmitigated evil," Justice Stephen Kaye said in sentencing Todd last month.

Ms Dixon had been "totally vulnerable and defenceless" when she was raped and killed in the park and Todd was driven by a "dark and sick fantasy," Justice Kaye had said.

After the murder, the then-19-year-old bought a pie and coffee and returned to the Carlton North crime scene.

He subsequently searched for news about the crime and also watched disturbing rape and "snuff" pornography.

Todd was diagnosed with sexual sadism disorder while in custody and had already been diagnosed as autistic.

Before the murder, he'd fantasised about violent non-consensual sex culminating in a woman's death.

Counsel Mr Marsh mentioned the appeal while representing another killer-rapist, Codey Herrmann, who has pleaded guilty to the murder of a 21-year-old woman in Melbourne's north.
