Peachey joined the Panthers in 2014 and the following season he won the prestigious Merv Cartwright Medal, awarded to the Panthers Player of the Year, while also earning selection in the NSW City Origin side and Prime Minister’s XIII.
Better known as a livewire backrower, Peachey proved his versatility in 2016 by filling in at left centre for the Panthers.
He finished the season as the club’s second leading tryscorer (13 tries) and his impressive form again saw him play for NSW City.
“Tyrone has been wonderful for our club and I am delighted he will be with us for the next three seasons,” Panthers Executive General Manager Phil Gould AM said.
“He is an integral part of our plans going forward.
“The quality of football this young man has produced, along with his ability to play multiple positions extremely well, makes Tyrone a perfect candidate for representative teams into the future. I have no doubts he would excel at that level.”
