Early life Aaron Frank Mooy was born on 15 September 1990 in Sydney, Australia. At birth, he was given the name Aaron Kuhlman, but his surname was changed by his Dutch mother after she divorced his father during Mooy's early childhood. Mooy had minimal contact with his father, with their only meeting occurring when Mooy was a toddler, and briefly again at 14 during which his father signed forms for his Dutch passport. Mooy was unaware that he had a brother with the same biological father until his brother approached him during his time at Western Sydney Wanderers.

During his upbringing, Mooy developed an interest in watching Premier League matches, particularly favouring Manchester United. David Beckham became his favourite player, and he would watch Beckham's games and practice free kicks, often pretending to be him. His mother responded to his interest in football by registering him with the Carlingford Redbacks. His German stepfather, Alan Todd, would soon join to coach his team.

Mooy's early football journey included stints with various clubs such as the Carlingford Redbacks, Granville Magpies, Blacktown City, and Northern Spirit. He enrolled at the New South Wales Institute of Sport (NSWIS) at Sydney Olympic Park and attended Westfields Sports High School. Mornings were dedicated to training, while afternoons were reserved for academic classes. Mooy left his home country at the age of 15 to pursue his ambitions.
