A musician who has become a cultural ambassador on the world stage has been recognised as the Australian of the Year in the Northern Territory.

Grant Ngulmiya Nundhirribala, an internationally recognised musician, who is also a cultural leader in Numbulwar community, Arnhem Land, received the award at a ceremony at the Darwin Convention Centre on Monday night.

Nundhirribala, 49, has inspired Numbulwar's next generation to excel at performing their traditional music and dance, showing them how to earn an income from expressing their internationally esteemed culture, in a place where employment is scarce.

Bridging cultural differences, he has been an ambassador for his music, language and culture across the world.

He collaborated with the Budapest Art Orchestra to release an award-winning album and worked in Japan with North Indian classical artists.

Community volunteer and founder of Seniors Of Excellence NT Michael Foley was awarded NT's Senior Australian of the Year, community service leader Nilesh Dilushan was judged The NT Young Australian of the Year, and wildlife carer and advocate Mignon McHendrie is the NT's 2025 Local Hero.

National Australia Day Council chief executive Mark Fraser congratulated the award recipients for their outstanding achievements and contributions.

"Grant's leadership is ensuring survival of culture and confident futures for people; Michael is a proud example of the value seniors bring to our society; Nilesh is drawing on his own experience to inspire and support others, and Mignon's dedication is protecting the unique wildlife that makes the territory and Australia so special."
