An enthusiastic crowd was present to witness the blessing and opening of the Sisters of St Anne's Ceduna convent on Wednesday.
The congregation - which originated in India in the 19th century - has a presence throughout the world, including in Ceduna and Port Augusta.
Sisters Nancy Ulahannan and Elizabeth Royan have been active in the Ceduna community since arriving earlier this year as part of the Centacare team and through their ministry.
Following a mass at Our Lady Star of the Sea Catholic Church, more than 50 people were present for the blessing of the convent on Lambeff Street.
Joining locals for the celebration were fellow St Anne sisters from India and Bishop of the Diocese of Port Pirie Greg O'Kelly, who conducted the service.
Sister Ulahannan said it was great to see the response from the local community.
"I was happy to see so many people, it shows how much people have welcomed us and appreciate what we are doing in the community," she said.
"We had sisters come from India to appreciate us and strengthen us, and the bishop, to make sure they are all with us in proclaiming the message of God."
Centacare Ceduna's Helen Walker said two years of work had been put in ahead of the opening, since initial talks with Sister Jacqueline Mary.
"She came here to talk about whether sisters could provide a service and this is the culmination of that hard work, but also a lasting resource for the community," she said.
"The sisters have blended well into the community.
"There are sisters all over India, in Africa and elsewhere, and they work with hospitals, women and children in lots of roles, and that global experience is a benefit to our community."
