Jaymes Todd, 20, was last month sentenced to life in prison with a 35-year non-parole period for raping and murdering Ms Dixon in Princes Park in Melbourne's inner north in June 2018.

Todd's legal team lodged documents for his appeal this week.

The Supreme Court was told of the appeal today by lawyer Tim Marsh during sentencing submissions for Codey Herrmann, who has pleaded guilty to the murder and rape of international student Aiia Maasarwe.

Mr Marsh is representing Herrmann and previously represented Todd.

A 'significant' risk of reoffending

During a plea hearing in August, the Supreme Court heard Todd was at "significant" risk of reoffending because he had sexual sadism disorder and had watched violent pornography before and after he attacked Ms Dixon as she walked home after performing comedy in the city on June 12 last year.

Over the year before the murder, Todd was obsessed with and addicted to a fantasy of "coercive rape" which escalated to include fantasies of death, and he searched the internet for "snuff films" which depicted violent sexual encounters ending in death, the court heard.

Justice Kaye said there were "poor" prospects of addressing Todd's sexual sadism disorder and he therefore had "very limited" prospects of rehabilitation.

"There was no evidence that your vicious act … troubled your conscience."

In addition to his life sentence for murder, Todd was sentenced to 11 years' jail for rape, seven years for attempted rape and two years for sexual assault.
