The 23-year-old, standing at 193cm tall, missed VFL action for most of 2025 due to injury.
As part of his recovery, Turner played in 5 games for a community club, Old Haileybury in the VAFA and earned two Best Player honours.
Turner has AFL experience, having been on the Melbourne Demons list for the 2024 season.
He has also played at VFL level with Port Melbourne and Frankston, and adds experience and talent to Williamstown’s deepening list.
All Seagulls fans will be excited to watch Turner make his on-field debut for Williamstown in the 2026 VFL season.
