Chooka was the first performer to showcase his talent on the Channel Seven program last night, having featured in ads for the show leading up to last night's series opener.
Chooka received a CD of classical performer Wolfgang Mozart but had to wait two years before his family purchased a CD player so he could listen to it.
The sounds changed his life, with the naturally talented musical youth teaching himself to play the piano and read music.
Chooka entered the television competition, which he had never heard of until late last year, after friends at shearing school heard him play his Casio keyboard.
He only performs original music that he makes up spontaneously, never repeating a previous performance.
Fans of the program took to their Twitter and Facebook accounts to heap praise upon the teen after watching his performance.
The Parker family borrowed a television to watch their son and brother showcase his talent.
Chooka said the family switched off the television after watching their first ever Australia's Got Talent episode and returned to their normal nightly activity, listening to him play.
"We stopped watching after that," he said.
"It was quite enjoyable watching all the performances.
"I think the best thing about Australia's Got Talent is meeting all these new people who can do all these different things.
"It was quite amazing, very, very impressive."
