In December 2005, Neeskens was appointed assistant coach of the Australian national team, once again at the request of Guus Hiddink, the Socceroos's manager at the time. He worked alongside Hiddink and Graham Arnold as part of their World Cup 2006 campaign, and even afterwards he remained involved with the Australian national team: on 7 October 2006, under contract with FC Barcelona, Neeskens was alongside the Australian national team's bench in a friendly match between Paraguay while visiting Australia for a short break.
