Zombies have taken to the streets of Brisbane for the 10th Zombie Walk, raising money for the Brain Foundation of Australia.

The walk draws thousands of people each year and broke the world record for the largest zombie walk in 2011.

Organiser Anthony Radaza said the event had reached many milestones over the years.

"We started the walk just as something to get people together, people who love, you know, the horror genre and zombies and just to really make friends," he said.

"Throughout the years it started growing from there and we decided to become affiliated with the Brain Foundation and raise awareness and funding.

The walk has drawn large crowds in the past and has raised more than $100,000 for the Brain Foundation.

Mr Radaza expected record-breaking crowds this year.

"It's the biggest Halloween party in Australia really," he said.

"You've got 20,000 people dressed up as zombies."

"Friend invited me so I thought, why not?" she said.

"I am an un-dead jail escapee who has been stabbed.

"I saw a kid smile at me, so started to doubt myself [that I was scary]."
