Australia
Huddart moved to Australia to play for NSWRFL club St. George from the 1964 season. It was hoped he could help fill the large shoes left in the record-breaking champion St. George side's second-row by the retiring Norm Provan. Huddart went on to help the Dragons continue their dominance in that period, scoring a try in the 1966 NSWRFL season's Grand Final victory over Balmain. The turning point of that match came when Huddart and Ian Walshput on a set move as the Balmain defence rushed up too early. Walsh burst through the line and with only the fullback to beat and passed the ball to Huddart who raced 30 yards to score. Huddart thus became the first Great Britain Test player to win a premiership in Australia. Huddart returned to Britain in 1970–71 to play a final season with Whitehaven.
