Growing up in England, Rebs Baigent was a major fan of Halloween.
"Every year as kids we'd dress up and be out trick-or-treating," she said.
"It was a massive thing.
"When I came to Australia 12 years ago, Halloween came around and there was nothing... Then about five years ago I started to notice that things were coming into the shops.
"It's been slower to break into Australia, but now it feels like it's everywhere."
She's organised the inaugural All Hallows Fest community event at Dapto Showgrounds on Saturday from 10am to 6.30pm.
Ms Baigent described it as a "big fancy dress party" for adults and kids.
She has previously run spiritual expos, and said many of the people she worked with liked to celebrate Halloween and pagan beliefs.
"It's natural that we started to evolve into this, because Halloween is a big celebration within those communities.
"We've got a mixture of supernatural, paranormal, witches, shaman and things like that... That is genuinely their life, they are witches.
"They'll be doing some workshops (this weekend).
"And we wanted to bring in the community as well, because often families want to take their kids, and kids want to dress up."
The day will also feature food, music, fire-breathers, dancers, face-painting, a Little Monsters Disco, a Haunted House, markets, psychics and plenty more.
"Open your mind to joining people who really authentically celebrate Halloween and alternative lifestyles," Ms Baigent said.
"Be brave, because it's a fancy dress party... But have fun, because it's going to be fun for the family, and there will be so much stuff to experience.
"If you want to have fun and dress up, this is the place to be."
Ms Baigent said they were aiming to make it an annual event, with discussions taking place for the 2020 event to be held on Halloween itself on October 31.
Entry is $5, and admission for under-15s is free.
Additional changes will apply to services such as amusement rides.
