"I like to write so I thought I would give it a go."
Aidan says he wrote the essay at home and didn't actually tell anyone he was entering.
"It was a real surprise to the school to hear that Aidan was a winner but we are incredibly proud," said deputy principal Haydn Wright at the special assembly that was called in Aidan's honour on Wednesday.
As well as winning the giant prize pack for himself, Aidan also won a prize pack of supplies for the school from Office Max and a $750 voucher for the school to spend on resources.
Aidan, who only found out he was the winner at the assembly, says he is glad he took a chance on the essay writing competition and encourages others to give similar competitions a go.
"It was definitely worth it. I am just so lucky to have someone as inspirational as my Nana in my life."
