TEENAGE international blues sensation, Lil G, will head the guest star line-up at Cooma's Australian National Busking Championships (ANBC) grand finals event on November 30.

ANBC president, Allan Spencer, said he was "over the moon" to secure the "incredibly talented' 12-year-old singer guitarist, who released her first single 'So They Say' earlier this year after recording it in America.

"Gemma comes from the Central Coast and has been part of the busking competitions here in Cooma before and now she is coming back as a special guest artist, and I am really excited," he said.

"She will play at the welcome party at the Alpine Hotel on the Friday night, on the main stage in Centennial Park during the day, and at the after party on the Saturday night."

It is not the first time Lil G has been a guest of the ANBC. Last year, she ran some workshops and played live.

Lil G took up guitar in 2019 after listening to a variety of musicians and genres who have since played an influential role in shaping her signature sound.

Earlier this year she toured in America, including being invited to perform at the national Museum of African-American music in Nashville, the world famous Reds juke join in Clarksdale Mississippi.

Mr Spencer said many buskers who qualified for the national grand final by winning or placing highly at the seven regional heats around Australia had indicated they would be competing on the day.

"The quality of the musicians and performers heading to Cooma for the national grand finals is astounding," he said.

The invitations have gone out to all the category winners from the regional finals and already we have heard from the likes of Coral Renee, who won Open at The Entrance and has recently released her single 'Pink Is My Colour', Noah Robertson (Stanthorpe and Noose Secondary), Tilly Rose (Kilmore, Secondary), Gabi Forman (Cooma, Open), Maverick Leslie Fitch (The Entrance, Secondary), CMAA Academy Country Music graduate Ruby Holden (Bombala, Secondary), Paul Shorten (Primary, Cooma), fellow graduate Belle Norman (Primary, The Entrance), local Bombala family trio Ron, Gaylene and Gus (Bombala, Band), Sloan Family (Band).

"Everything is shaping up to be the biggest and best national grand final yet," he said.

The event will get underway with the welcome party on the Friday night, open to all, continue with a multicultural street parade at 9am on the Saturday followed by busking performances and acts on the community stage between 10am and 4pm, a winners' concert and then an after party.
