The changing of the guard continues in Queensland with the state’s greatest ever fullback Billy Slater confirming the 2018 State of Origin series will be his last in a Maroons jumper.

It also ends a glittering career in the green and gold for the Australian Kangaroos.

Speaking at a press conference on Tuesday morning, Slater, at 35-years-old, said his time was up.

“I just feel it’s time,” Slater said.

“To be honest, I can’t give you a real answer on why exactly (I’m retiring), but I’m 35 this year, this will be my 15th year for Queensland.

“I had a fair indication that the World Cup last year would be the last time I played for Australia, it’s been on my mind for a while, I always felt this would be my last Origin series.

“The guys that have gone last year (Johnathan Thurston and Cooper Cronk) and Cam’s (Smith) decision had no bearing for me.

“I just made the decision myself.

“The pressure is relieved letting everyone know and being honest.”

Amazing @billyslater.

Coach Kevin Walters had nothing but praise for the iconic custodian.

“He has changed the way fullbacks play and to have him for 15 years is a dream for all Queenslanders,” Walters said.

“Everyone would remember Billy’s great Origin try and that makes kids want to be like Billy Slater.”
