Dances and foods from several countries will be on offer to Wimmera residents at Horsham's Country Women's Association hall this weekend.
Oasis Wimmera will for the first time stage a free event to celebrate the festival known as Diwali from 6pm on Saturday.
President Anubha Jalla-Das said everyone was welcome, and Horsham families from Pakistan, Nepal and Bangladesh would be among those attending.
"I have organised one classical dance, and some children under five are doing a group performance on that day," she said.
"Diwali is a popular festival in India, Nepal, Myanmar, Fiji and Sri Lanka," she said.
"In Hindu religion, there is a very famous story about a king called Ram, who killed Ravaan who was evil in character, so it is all about good over evil. When Rama came back to his family, the family celebrated, and later on that celebration became Diwali.
"(At the Horsham event) we will do Rangoli, which is sand and rose petal art we make on the floor, and we will do henna tattoos and we have traditional costumes and jewellery to try on."
Oasis Wimmera supports up to 60 Horsham migrant families, helping them to integrate into society through programs such as monthly social gatherings and fitness programs.
Mrs Jalla-Das said Horsham residents could help the organisation in this regard by attending the event and learning about the cultural events on display.
"Some of the families coming to this Diwali event are from Natimuk, Dimboola and Nhill. They are working all day but they still want to join this festival," she said.

"People will learn about the tradition, culture and heritage if they come along. It's all about socialising and mingling with others.
"We are happy to promote different traditions and heritages - it's not all about Indian culture. The ex-president of Oasis told me they have celebrated Japanese festivals, and we are expecting next year to celebrate Teej festival, which is very famous in Nepal."
In India, the annual five-day Diwali festival will begin on Friday October 25.
