The National Trust of South Australia (NTSA) was founded on the simple and enduring idea that people need historic, beautiful and natural places. NTSA is a leading community organisation for the protection, preservation and promotion of SA's built, cultural and natural heritage. We are part of a worldwide movement of more than six million people in more than 60 countries committed to the future sustainability of our cultural heritage and natural environment.

NTSA manages 125 historic places and nature reserves with the support of our members and volunteers across the state. We advocate for effective protections and investment in sustaining our heritage and deliver unique experiences and learning opportunities for people of all ages in a range of indoor and outdoor environments. We undertake cultural and natural heritage regeneration projects to create social and economic value for the community. We are an independent community voice for the future of our heritage.
