More than 120 remote community stores have joined the Federal Government's Low-Cost Essentials Subsidy Scheme in its first year, with ministers touting the program as a key cost-of-living measure for First Nations communities.

The scheme, administered by the National Indigenous Australians Agency (NIAA) and delivered by Commonwealth-owned not-for-profit Outback Stores, subsidises the cost of 30 essential household items to bring prices closer to those paid in urban centres.

Eligible products include milk, rice, tinned vegetables, canned fruit, toilet paper and nappies.

Since launching 12 months ago, 68 stores across the Northern Territory have joined the scheme, alongside 34 in Queensland, 15 in Western Australia and three in South Australia's Anangu Pitjantjatjara Yankunytjatjara (APY) lands, the government said in a statement on Wednesday.

Minister for Indigenous Australians Malarndirri McCarthy said the program was designed to reduce the higher cost of essential goods faced by people living in remote communities, arguing the scheme is about "fairness and easing cost of living pressures for remote First Nations communities".

"Everyone deserves access to affordable essentials, no matter where they live," she said.

"I'm pleased 120 remote stores have so far signed up to the Low-Cost Essentials Subsidy Scheme to offer cheaper food and other essentials to their communities, and I encourage more stores to apply."

Earlier this year, the scheme was expanded, with an estimated 225 remote stores across Australia now able to apply as part of a $27.4 million investment. An additional $32.7 million will fund freezer equipment for 75 stores to improve food storage during periods when access is cut off.

The scheme requires eligible retailers to adopt the new National Code of Practice for Remote Store Operations. The government has said the expansion will lift coverage to an estimated 225 stores across the country.

Independently managed outlets make up around half of all remote stores and are considered essential services for their communities, they added.

The program has supported almost 4,000 deliveries over the past year, with more than three million subsidised items delivered to remote communities.

Special Envoy for Remote Communities Marion Scrymgour said the program was helping ease financial pressures in regional and remote Australia.

"Our remote communities are unique places, and they deserve the focus of government. That's why 12 months ago we rolled out this targeted cost-of-living package to help people in remote communities access essential items," she said.

"Creating healthier communities starts with affordable essentials and I am proud that the Low-Cost Essentials Subsidy Scheme has been delivering cheaper goods for people living out bush for 12 months now."

Last month, the government said it has reached an early milestone in its efforts to build a locally led nutrition workforce in remote First Nations communities, with 21 "Good Food People" now employed in community stores across northern Australia.

The Good Food People program trains and mentors local workers to promote healthy eating, improve food security and support healthier food choices in remote communities. The initiative has been rolled out across the Northern Territory, Western Australia, Far North Queensland and the Torres Strait.

Speaking to National Indigenous Times last year, Senator McCarthy said the workers are employed in stores to help customers make healthier choices.

"They have to be based around food," she said.

"It's about awareness in language; making it understandable about what foods are healthy for you, what foods are not; what's the better choice.

"So, these nutrition workers are also about assisting. If you do have Mob who come in with kidney dialysis issues or with heart issues, they have a sense of how they can guide customers as well."
