Brisbane Broncos confirmed South Sydney Rabbitohs coach Anthony Seibold would replace Wayne Bennett at the helm on a four-year deal beginning in 2020.
Bennett, 68, will see out his final year with the Broncos in 2019 before leaving to take charge of the Rabbitohs.
The Broncos confirmed Bennett's departure in September and on Wednesday announced Seibold – the 2018 Dally M coach of the year – would take the helm.
"We have been through a robust process and interviewed a number of high-calibre coaches," Broncos chairman Karl Morris said in a statement.
"Anthony was a standout. His football knowledge is exceptional, as is his thinking and process around people management.
"He also has a strong commitment that will add to the commercial and community aspects of our club, which is extremely important to the Brisbane Broncos."
Brisbane have made the finals in each season since Bennett's return in 2015, but were thrashed by the St George Illawarra Dragons in the first week this year.
While Broncos chief executive Paul White is excited about 2019, he was delighted to seal the appointment of Seibold.
"We have done a thorough due diligence and as a result we have got the best person for the job in Anthony," he said.
"Our job is to look after the long-term future of this club and that is what we have done through Anthony's appointment.
"Anthony is one of the best young coaches in the game and having him for 2020 is a huge win for our members, players, staff, sponsors and fans.
"Planning is well and truly underway for next season and we are expecting big things from the team – it's a season we can all look forward to."
