Six Aboriginal organisations have secured more than $416,000 to safeguard culturally significant sites scattered across Western Australia's Pilbara.

The state government's Preserve, Promote and Protect our Aboriginal Sites grants program will channel the funding into nine projects.

Mugarinya Community Association, Wanparta Aboriginal Corporation and Kariyarra Pirnthurruna Aboriginal Corporation each landed support for two projects apiece.

Warrindahs of the Ngurra, Budadee Aboriginal Corporation and Gobawarrah Yinhawangka Aboriginal Corporation also made the list of successful recipients.

The projects range from protecting burial grounds and conserving heritage sites to installing fencing, interpretive signs and recording the cultural knowledge of Traditional Owners.

Mugarinya Community Association picked up $50,000 for work at Peawah Ridge and Wogulana Rock.

Their project will map culturally significant sites, record cultural knowledge, install fencing and signage, manage vegetation and promote the sites online.

Budadee Aboriginal Corporation secured $46,709 to install signage at the Woodstock-Abydos Protected Area.

Elders will join consultations and on-Country visits to steer the design and placement of the new signs.

Aboriginal Affairs Minister Don Punch said the projects would protect places of cultural significance while preserving stories and knowledge for future generations.

"Aboriginal communities are leading this important work on Country, combining cultural knowledge with practical conservation activities," he said.

"These projects go beyond protecting physical sites.

"They support truth-telling by recording and preserving Traditional Owner knowledge."

Pilbara MLA Kevin Michel said the funding would help communities care for Country and strengthen cultural connections.

"These grants will support local communities to care for Country, strengthen cultural connections, and ensure future generations can continue to learn from and celebrate the Pilbara's rich Aboriginal heritage," he said.

Pilbara projects claimed $416,482 from the $1.25 million spread across 30 initiatives statewide.
