He has strong family connections to Queensland with his surname deriving from his great-great-great grandfather who was known as 'Old Man Cockatoo' in the Cape York Peninsula[5] as well as three of his Queensland-based uncles Che, David and Donald playing professional football in the AFL.[6] Several female cousins of his are also involved in the Gold Coast Suns' developmental football academy.[7]
At the conclusion of the 2020 AFL season, Cockatoo was traded to the Brisbane Lions,[10] where he would play 15 games before retiring at the conclusion of the 2023 season.
