Holman played 63 internationals for the Socceroos following his debut against Bahrain in 2006 and was a member of the Socceroos squad at the 2010 World Cup in South Africa.
It was in South Africa where Holman was at the peak of his powers, scoring goals against Ghana and Serbia to be just the second Australian to score two goals at the FIFA World Cup, following Tim Cahill’s twin strike against Japan in 2006.
FFA CEO David Gallop said: "Brett’s decision to retire from international football brings down the curtain on a distinguished career with the Socceroos and we would like to recognise Brett for what achieved in a Socceroo shirt.
"After starting his career as a grassroots player in Western Sydney, Brett scaled the heights of international football and will be forever remembered for his goals at the 2010 FIFA World Cup when the Socceroos went within a whisker of qualifying for the second round in South Africa.
"Brett is another shining example of the pathway football offers young people from the grassroots to the world stage and we look forward to publicly acknowledging his contribution to our game."
Socceroos head coach Ange Postecoglou, who has been charged with the task of regenerating the national team, also acknowledged Holman’s achievements.
"I’d like to congratulate Brett on his Socceroo career and applaud the contribution he made to the team during his seven years with the national team," Postecoglou said. "He is one of a few Australian players who can proudly say they scored a goal for the Socceroos at the World Cup and his achievements will sit nicely in Socceroo history."
