Trent Robinson is set to clock up at least 16 seasons as coach of the Sydney Roosters after the NRL club extended his contract until the end of 2028.
Already the longest-serving coach in club history, 44-year-old Robinson is currently in his 10th campaign.
He led the club to the NRL premiership in his first year in 2013 and became the first coach in the NRL era to claim back-to-back trophies, with further success in 2018 and 2019.
Roosters chairman Nick Politis said the club wanted to lock in one of the game's "best thinkers".
"In my view, Trent is the game's best thinker," Politis said in a statement.
"He is a man of high integrity with a genuine love for his players, the history of our club and the area we represent.
"Every player that we have signed since Trent came on board as head coach in 2013 has become a better player and person, and it's wonderful to know that Trent will continue to lead the way at the Roosters well into the future."
Robinson, who spent two seasons coaching Super League club Catalans before joining the Roosters, said the Sydney club was his home.
"This club has been the biggest part of my working life; it is unequivocally my home,"Robinson said.
"The Roosters is in my DNA, and as a leader, my role here is pretty clear.
"Walking in to our offices every day, seeing the quality of staff and players we have here, we're all committed to striving to be the best sporting franchise in Australia, and I'm incredibly proud to extend my time with the club."
The only current NRL coach with a longer tenure than Robinson is Melbourne mentor Craig Bellamy, who is in his 20th season in charge and is signed until the end of 2026.
