Local councillor Ajay Kapoor (Sachin Joab) has been appearing as a guest on the show since the summer, while his wife Priya (Menik Gooneratne) has also featured on screen.
The couple will become regular fixtures in early 2012 along with their teenage daughter Rani, who will be played by newcomer Coco-Jacinta Cherian.
Neighbours' executive producer Susan Bower commented: "I'm delighted by how the Kapoors have been introduced. Viewers already know them because of their role in the community and link with other characters, and their cultural background is secondary.
"We have had many individual characters who have been representative of Australia's diverse cultural landscape, however to have a family of Indian and Sri Lankan heritage join the neighbourhood is very exciting."
Neighbours' Australian fans have already seen Priya appointed as the acting principal of Erinsborough High. UK viewers will see her in action at the school in upcoming episodes.
Bower first revealed plans to introduce a new family to Neighbours in an interview with Digital Spy earlier this year.
Speaking in the summer, Bower explained: "A new family will join the show but not for a while. We need to let our stories be told in a natural way.
"It has been shown in the past if a moving van pulls up in Ramsay Street and a new family comes in, it is a trigger for the audience not to like them so we are introducing a family in very small doses. We will meet one, then another so the characters are accepted."
Neighbours airs weekdays at 1.45pm and 5.30pm on Channel 5 in the UK and weekdays at 6.30pm on Eleven in Australia.
