The man who vandalised slain comedian Eurydice Dixon's memorial says he doesn't regret his actions and believes some people would be "proud" of what he'd done.

The former comedian and "independent Scientologist" Andrew Nolch told A Current Affair he carried out his graffiti attack because it was the most anti-feminist thing he could think of.

"I think what came to mind was what would annoy feminists the most," he said.

Nolch, 31, has admitted to sprawing a lewd symbol in the park where Eurydice was found dead in June and has said he plans to plead guilty in court.

Despite claiming an anti-feminist agenda, he has also claimed his actions were motivated by anger that the media was not factoring a debunked link between vaccinations and autism into the reporting of Ms Dixon's death.

The man charged with her rape and murder, 19-year-old Jaymes Todd, has been diagnosed with autism spectrum disorder, his lawyer told court in June.

Nolch said he did it to "annoy feminists" and because he was angry about a debunked link between autism and vaccinations. (9news)

Nolch now claims some of the backlash to his obscene vandalism has been "offensive"

"It wasn't an attack at all on Eurydice, I didn't know her personally and I apologise completely to her family," he said.

"It could have been anyone, it could have been any girl or anything."

Dixon was found dead in a park in Melbourne in the early hours of July 13. (9news)

He said his actions had been "planned but rushed" over a matter of hours.

Nolch also told A Current Affair he thought feminism had a "negative affect" on women, before praising One Nation leader Pauline Hanson.

"I feel like the tragic death of a young comedian was being turned into a women's rights issue," he said.

His father Paul nonetheless claimed Nolch "loves women".

Meanwhile, Nolch's brother Vinny claimed that Nolch also had been diagnosed with autism at 10 years old.

"All I'm say is an autistic kid (drew) a penis on the ground, what do you expect," he said.

Nolch did not confirm his brother's claim, saying he thought Vinny had been "shocked" and didn't know what to say.
