Kalparrin, situated at Murray Bridge, is a recovery program to help such problems as alcohol and drug abuse or trans-generation grief of the stolen generation.

Kalparrin chairman Marshall Carter said it was a very important day.

"It's good to see everyone here," he said.

"It's 30 years we've been giving service, people come from all over Australia to our community.

"I'm very excited and proud to be part of it."

Mr Carter said there were not many Aboriginal organisations left in South Australia.

"It (today) is very important to us," he said.

He said there were representatives from many organisations at the celebrations.

"(There's many here) who made Kalparrin who it is today," he said.

"All of the grass roots."

Kalparrin Community Inc director Clyde Rigney Snr said he wanted the to be a day of celebrations of 30 years and the recognition and contributions of many people.

"It was a great day and a good opportunity for people to fellowship," he said.

"We didn't want anything too formal."

"It started as a vision from some of our elders," Kalparrin community fellowship team leader Gary Paynter said. He said some of the elders saw that there need to be a place to live and recuperate and then it developed into a recovery program.

Starting without a budget and no money, Kalparrin has grown over the years.

"It's a peaceful place," he said.

"Alcohol free and drug free.

"Kids can run around at night and not be at risk.

"It's a place where if you have a problem, (there's) someone to yarn to."

More than 200 people attended the event at the community situated on the Karoonda Road, Murray Bridge, and were treated to lunch, entertainment and fellowship.
