Shannon made his one and only appearance for the Socceroos in the lead-up to the 2010 World Cup, in an Asian Cup qualifier against Indonesia in Brisbane.
The club Shannon has nominated sadly no longer exists but played in the huge NSW Churches Association. Yaralla SC played out of Powell's Creek Reserve in Concord, near the Sydney Olympic site & it, like the club, sadly is no longer around, having been subsumed by a school. My thanks go to Paul Stipack for the Yaralla shots & the NSW Churches network.
