Bush to Beach founder Jack Cannons says he wants to expand the program after participants marked 20 years of giving bush kids a taste of the ocean.

Each year, the program takes Indigenous children from Brewarrina, Bourke and surrounding communities to Sydney's Northern Beaches to reward school attendance and promote their confidence.

Mr Cannons said he want to see it grow "right around the country."

"There's no reason why the coastal city surf clubs can't adopt a town in the bush that needs some support," he said.

"We've got some great supporters and we just need some more as a charity to grow and hopefully operate in different parts of the country.

"I've got so many communities on a waiting list."

He said travel, accommodation and insurance costs - now higher than they were twenty years ago - are a challenge to expansion.

In January this year, 40 children from Brewarrina and Goodooga took the 12-hour trip for a three-day program.

They were hosted by the South Narrabeen Surf Club and were given swimming, snorkelling and surfing lessons.

"We had a little 10-year-old that had never been in the ocean. She rode nine waves after about half an hour," Mr Cannons said.

"The confidence she gained from that was just amazing."

Mr Cannons was inspired to develop the program after a conversation in the early 2000s with late Brewarrina elder Aunty Joyce Doole.

The first trip took place in 2006.

The twentieth anniversary was celebrated with a special badge and a towel emblazoned with a turtle painted by an original participant.
