A woman is over the moon at the prospect of marrying notorious Australian serial killer James Vlassakis.

Bianca Roberts told the latest edition of Australia's That's Life magazine she would marry Vlassakis on Sept. 2 - even though he will not be eligible for parole until 2025, Adelaide Now reports.

"We've been together for almost seven years," Roberts told That's Life. "I wish we could be together like a normal couple but you can't help who you love and I'm prepared to wait for James, even until 2025 when he will be eligible for parole."

"I know that some people reading this will find it hard to understand how I could marry a serial killer but that's not how I choose to see James," she said.

Roberts told the magazine she had been Vlassakis's first girlfriend for 18 months when they were aged about 11.

Eleven people were murdered in South Australia between 1992 and 1999, eight of whom were found dismembered in barrels of acid in a Snowtown bank vault on May 20, 1999. Vlassakis pleaded guilty to four of the murders and was jailed for life, with a non-parole period of 26 years.
