 St Ledger scored his first goal for Ireland in a 2–2 with Italy at Croke Park, Dublin, in a FIFA World Cup qualifier in October 2009.The goal gave Ireland a late lead against the World Champions and was almost St Ledger's "Ray Houghton" moment, guaranteeing him iconic status in only his sixth appearance, only for Alberto Gilardino to score an even later equaliser for the Italians.On 12 October 2010, St Ledger scored his second goal for Ireland in a UEFA Euro 2012 qualifier against Slovakia which finished 1–1.
