Former Kangaoo Greg Alexander believes the Australians are officially at the end of an era and it’s time for change.

Writing in this week’s Big League, Alexander wants a gradual changing of the guard.

“You’d imagine the Kangaroos side will have a vastly different look when it takes to the field in a year from now, let alone at the 2017 World Cup,” said Alexander.

“Two-and-a-half years is a long time for a 32-year-old.

“Cameron Smith, Corey Parker and Johnathan Thurston were very good on Sunday, and the majority of the older crew have played a crucial role in the Kangaroos’ dominance.

“There comes a time for change, and it’s upon Australia, but it’s important that the rollover in personnel is gradual, as bringing a whole new team of rookies together for the first time could make them like lambs to the slaughter.”
