A modern 17KW solar, battery and backup diesel generator system is being installed on the Mawonga Station in central-western New South Wales so local communities can access clean and reliable energy.

The project on the 22,373-hectare Mawonga Station - and Indigenous Protected Area - near Roto, north of Hillston, will broadly support the Traditional Ngiyampaa Wangaaypuwan people and ensure a safe living and working environment to support ongoing land management across the property.

Almost $50,000 funding from the Indigenous Land and Sea Corporation helped facilitate the modern renewables system that will power Mawonga Station's Shearers Quarters, providing reliable electricity for five Winangakirri rangers, their accommodation and operational facilities, as well as cultural camps and On-Country activities, while reducing dependence on diesel.

The Indigenous Protected Area of Mawonga represents the cultural and environmental significant of the land, which was divested 10 years ago to the Winangakirri Aboriginal Corporation (WAC), the organisation representing Traditional Owners.

After a lengthy struggle, the 22,000 hectares of land was handed back to the Ngiyampaa Wangaaypuwan people at Mawonga Station in 2015 after a community push to acquire a former pastoral lease.

At the time, Mawonga Station became the biggest piece of Indigenous protected land in Southern Australia.

"Keewong Family descendants and the broader Aboriginal community went through a long journey to gain rights to our Country and hold title to land," WAC told National Indigenous Times.

"This is something Aboriginal people were excluded from for much of the 20th century... to continue to take care of Mawonga. They want to continue the role of their ancestors."

WAC board chair Madison Penrith said the solar power system was a game changer.

"Whether you are a part of the community, a ranger, a Traditional Owner or a board member, we are all deeply connected to Ngiyampaa Country," she said.

"The solar and battery installation will enhance how we all work to conserve this land's natural wonders."

Mawonga holds deep spiritual connection to the local Indigenous community, with Traditional rock art sites, camping areas and travelling pathways a reflection of the history and cultural practices of Ngiyampaa Wangaaypuwan people.

The property supports important ecological systems, including mallee woodland ecosystems and habitats for native species, including the Yungkay (Malleefowl) totem.

WAC deputy chair Stacey O'Hara said the Shearing Quarters was an important keeping place for sacred Ngiyampaa artefacts, with reliable power essential for preservation.

"We thank the ILSC for their generous support and look forward to our solid partnership continuing," she said.

ILSC group chief executive Joe Morrison said a transition to clean energy enhanced the role of Traditional Owners to care for their Country.

"We look forward to seeing Mawonga thrive following the installation," he said.

Power failures were common at Mawonga during extreme heat, with food supplies lost, increasing financial and logistical challenges for Mawonga, which is 80 kilometres from the nearest town.

A predicted reduction in annual diesel spend of $20,000 would be reinvested into Mawonga's land management and ranger activities, which included cultural heritage protection, fire management, pest control, biodiversity monitoring and development of visitor and cultural tourism opportunities.
