Cadee was born and raised in the Sydney suburb of Greenacre. He attended Westfields Sports High School in the nearby suburb of Fairfield West, where he earned Hall of Fame status for basketball. He grew up playing for the Bankstown Bruins junior program. In 2008, Cadee made his debut in the Waratah League for the Bruins. That same year, he was named the NSW Male Athlete and Basketball Player of the Year. In 2009 and 2010, he attended the Australian Institute of Sport and played for the program's SEABL team. He also played for Bankstown in 2010, earning the Waratah League's Australian U/21 Youth Player of the Year and All-Star Five honours.

In July 2010, just months after signing his first professional contract with the Gold Coast Blaze, Cadee was involved in a car accident on Sydney's M7 Motorway. A semi-trailer had veered out of its lane and pushed him off the road. His car went into a spin and parked itself at right angles across one of Sydney's busiest highways. In an instant, Cadee was crumpled against the middle console of the car. After being trapped for 90 minutes, somehow, he escaped with just a broken pelvis. As a result, his NBL debut was delayed and he was forced to withdraw from the Australian Boomers squad.
