Kosakowski, who made his debut as Billy in Sydney in 2007, was the only actor to play the lead role in both the Sydney and Melbourne seasons of the hit show.

He finished up with the show in 2009 after growing too tall for the child role that won him a swag of awards.

After Billy Elliot, Kosakowski, now 16, began full-time training at the National College of Dance with Marie Walton-Mahon and studies many styles of dance.

He will join fellow dancer Sharlene Roberts, pictured, for a performance of the Rachmaninoff Suite as a tribute to Walton-Mahon at the school’s end-of-year concert and her farewell on Saturday .

‘‘Everyone is training so hard because Marie has done so much for our careers,’’ Kosakowski said.

The new artistic director for the National College of Dance and the Marie Walton-Mahon Academy, Brett Morgan, has been working alongside Walton-Mahon for the past six months to ensure a smooth transition into the 2011 season.

Morgan has recognised Kosakowski’s talent and has offered him a professional contract with his all new MOD Dance Company, based in Melbourne, for 2011.

‘‘Everything I ever wanted was to have an affiliated dance company for my students here in Newcastle to aspire to be contracted to after they graduate. I am delighted they will now have that with Brett and MOD,’’ Walton-Mahon said.

Walton-Mahon’s daughter Veronica Mahon has also been offered a full contract with MOD.

After 36 consecutive years of producing her well-known end-of-year concerts, Marie Walton-Mahon is putting the finishing touches on her final ever A Night to Remember.

Tickets are sold out for the December 11 evening event, but are available for the 10.30am dress rehearsal from the Civic Theatre.
