Payne continued his impressive VFL form by kicking four goals against the Cats. while Phillips had 20 touches and four clearances.

Harvey missed Round 20's match against Geelong due to illness.

Captain Jy Simpkin will miss Sunday's Marvel Stadium match against the Saints due to a knee injury. 

Big forward Finnbar Maley has been omitted this week. 

The Kangaroos will name their selected team at 5pm on Friday.
