The Australian government is set to establish 12 new Indigenous Protected Areas (IPAs) following a $14.6 million investment.

IPAs are areas of land and sea country managed by First Nations groups, and the announcement will go towards the government's commitment to protect 30 per cent of land by 2030.

In a joint statement on Wednesday, Minister for the Environment and Water, Tanya Plibersek, and Minister for Indigenous Australians, Linda Burney, said IPAs help deliver better nature protections and good local jobs.

"No one knows this country better than First Nations people who for time immemorial have cared for our land and sea," Ms Burney said.

"These new IPAs will mean local Aboriginal and Torres Strait Islander people will have the opportunity to manage and care for Country. Importantly, the Indigenous Rangers Program will help to close the gap by giving First Nations people work on Country."

More than 700 First Nations people, almost half being women, are employed through the IPA program.

The new projects will protect a combined 7.5 million hectares of land and 450,000 hectares of sea Country, on top of the 87 million hectares of land and five million plus hectares of sea Country already protected by existing IPAs.

"IPAs will embed traditional knowledge and expertise in the management of the land, ensuring the voices of First Nations people are heard when it comes to decisions about protecting and caring for their traditional lands," Ms Burney said.

"The success of the IPA program recognises the important stewardship of First Nations people in caring for Country for over 65,000 years, maintaining and reviving their cultural practices and delivering conservation outcomes for all Australians."

The government stated the expanded IPA program will support Traditional Owners to look after their Country and deliver on the Closing the Gap Implementation Plan.

Examples include the Yurruungga Aboriginal Corporation and the Jagun Alliance Aboriginal Corporation in NSW helping to improve the trajectory of threatened species, including the Swift Parrot and the Regent Honeyeater.

"Our investment to establish 12 new IPAs will not only protect our biodiversity and rehabilitate areas in need, but it will produce more local jobs and opportunities for regional and remote areas," Ms Plibersek said.

"We're protecting an area the size of Tasmania – protecting native species, dealing with feral animals and weeds, managing fire risks, and restoring our beautiful Australian landscapes. At the same time, we're creating jobs and teaching a new generation to care for Country."
