Thousands of people have marched in Melbourne to remember Irish woman Jill Meagher, who was abducted and killed in the Australian city one year ago.

The 29-year-old Co Louth woman was taken from Sydney Road in Brunswick when she was trying to make a five-minute walk home after a night out with friends.

Adrian Bayley has been ordered to serve a minimum of 35 years for her murder and 15 years for her rape.

He lost an appeal last week to have his sentence reduced.

Artist Philip Werner, whose Facebook post last year sparked a 30,000-strong march to honour Ms Meagher and other victims, said he was not surprised that thousands again turned up to honour victims of violence.

"I've called it a peace march and I believe people are here because they want to express the opposite sentiment to the things that led to the murder," Mr Werner said.
