The 16-year old found out recently he would spend 2020 at the prestigious dance school, training with some of the greats.

Flynn will follow in the footsteps of fellow students of the Sydney performing arts school, MacDonald College, where he has been studying for the past two years.

Alongside his academic classes, Flynn and his classmates at MacDonald trained up to 30 hours a week.

In Philadelphia, Flynn will ditch the books to allow him to focus on ballet.

His mum, Madeline Fisher said training such long hours takes a huge toll on the body.

"I'm often asking 'have you stretched today?'" she said.

Mrs Fisher said her family are feeling more anticipation for Flynn than anxious about a year without him.

"It's been a dream of his for a long time," she said.

Flynn will spend his next few weeks training at his former school, United Dance Project.
