The New South Wales government and the Aboriginal Languages Trust have launched a five-year strategic plan to increase the use of Indigenous languages in the state.

Developed through consultation with more than 400 people from Indigenous communities and organisations, the plan seeks to support language groups and raise awareness of the value languages have to communities.

Aboriginal Languages Trust executive director Clare McHugh said Indigenous use of language must be prioritised over it's wider use in the community.

"Communities determine the use, growth and Cultural integrity of their respective languages and the Trust will uphold each Community's right to determine if they want to share their language with others, including non-Indigenous people," she said.

"We know and the evidence supports that the health and vitality of Aboriginal Languages is strongly connected to the health and vitality of Aboriginal people and communities.

"The process of revitalising language is a very emotional journey."

NSW Aboriginal Affairs Minister Ben Franklin said Aboriginal languages were being reawakened.

"The New South Wales government promised in legislation and by traditional message stick to invest in Aboriginal language revitalisation efforts and we are delivering on that promise with a commitment of more than $138 million over the next 10 years," he said.

"The Trust's strategic plan presents the opportunity to take a unique approach to implement policies and programs that will create genuine intergenerational change, which will be achieved by initiatives designed by, with, and for Aboriginal communities."

Ms McHugh said the focus now turned to designing the programs and initiatives that the plan outlines.
