From Devonian-era fossils to Djiringanj and Thaua sacred sites, there are now hopes the new resource will be taken on by museums, tourism operators and local schools.

South Coast History Society president Peter Lacey launched the Bega Shire's Hidden Heritage website and free app at Bega's Uniting Church on Monday.

Bega Valley Shire Council mayor Kristy McBain said the project has highlighted the natural, built and cultural heritage of modern day Australia.

Council's Carley McGregor also worked on the project, and said including the history of the region's traditional custodians was a crucial aspect.

"Our generation tends to forget about history, and that it started with our local Indigenous people," she said.

"One of our biggest aims was that it cover our entire history, and the conversation starters through this project have been overwhelming."

Dignams Creek resident Trevor King has 30 years' experience as a heritage consultant, and has been part of the team working on the new app.

"We've all learned a hell of a lot. It makes you look at things in a completely different way," Mr King said.

"Having the opportunity to work on a project like this was great."

He said the project avoided the cliche of colonial structures, and even includes flora unique to the area, photographed by Brogo botanists Jackie Miles and Max Campbell.

"We are just scratching the surface of what's out there," Mr Lacey said.

"Our team didn't want buildings because they are on lists everywhere, so it's opened the doors for other things, which is fabulous."

Mr Lacey said there has been interest from groups in Western Victoria, Yass and Canberra in developing a similar app.
