Killer Jaymes Todd is appealing his sentence for the rape and murder of budding comedian Eurydice Dixon in a Melbourne park.

Todd has been jailed for life and must spend 35 years behind bars before he can apply for parole for the June 2018 attack.

His lawyer Tim Marsh told the Supreme Court on Thursday during a hearing for another killer-rapist, Codey Herrmann, an appeal for Todd had been filed.

The Supreme Court on Thursday confirmed paperwork for leave to appeal against the sentence was lodged on Monday.

Todd stalked 22-year-old Ms Dixon for more than an hour as she walked through Princes Park after a comedy gig on June 12 last year.

After the murder, the then-19-year-old bought a pie and coffee, went back to the Carlton North crime scene and googled rape and pornography as well as stories about his victim.

He was diagnosed with sexual sadism disorder while in custody.

Before the murder, Todd fantasised about violent non-consensual sex culminating in a woman’s death.

During the sentence Justice Stephen Kaye said Todd’s “dark and sick fantasy” and the disorder drove the crime and not his mild autism.
