"Services Rugby League has gone from strength-to-strength during the past 10 years as result of the attention to detail both in the playing calendar and their preparation for this event.
"The players are of an excellent standard; they are very professional and focussed and their achievement was a result of the processes they have put in place.
"It is a satisfying experience for me to coach the World Cup winners and a privilege to be involved with everyone who has helped make that happen."
