Already signed with the Dockers to the end of 2026, Josh Treacy signs a four-year contract extension to remain at the club until the end of 2030.
The 21-year-old, whose shot accuracy of 70 per cent this season is the best out of the top 40 goalkickers in 2024, was happy to secure his long-term future.
"It was clearly a no-brainer with the situation the club is in and the way that I feel it is going to go," Treacy said.
"We've got a really big month ahead of us and hopefully we can go further."
