Australian Olympic paddler Jess Fox has been seen with a new romantic partner, identified by Daily Mail Australia as Jack Nelson. The revelation comes after months of speculation following Fox's quiet separation from her previous partner of nine years, French canoeist Mathieu Biazizzo, in May 2024.

Nelson, who previously played reserve-grade rugby league for Canterbury and Penrith, has transitioned to a career in equipment sales. He won the NSW reserve-grade premiership and State Championship with Canterbury in 2018. Fox, Australia's most decorated Olympic paddler, publicly announced she was dating again in May 2025 and subsequently appeared with her new partner on holiday.

Fox underwent surgery in August 2025 to remove a kidney tumor. She experienced complications during her recovery following the procedure. The details of her new relationship come to light as the athlete navigates her personal and professional life.
