The couple settled in Detroit in 2004, two years before their daughter Maya was born, and moved back to Australia in 2025 when Mick accepted a coaching role at the MCC Squash Club. Joint began playing tennis in kindergarten at the local Michigan courts when she would hit tennis balls with her father using a squash racquet.
