The Brisbane Broncos centre, who played football for the Clarets as a junior, started in the semi-final defeat to Samoa at the Emirates.
Despite Farnworth going over for a brace, it was not enough to stop Shaun Wane’s side losing 27-26 on golden point.
Here are some of his standout moments from the tournament:
