De Young, 32, is one of only four men to play more than 300 games for Australia and leaves the sport a three-time Olympic medallist, double World Cup winner, three-time Commonwealth Games gold medallist and four-time Champions Trophy winner.
He joins veteran midfielder Rob Hammond, who last week announced his immediate retirement from international field hockey following the Kookaburras` recent World Cup triumph in the Netherlands.
Long-time coach Ric Charlesworth, 62, has also announced he was stepping down before next month`s Commonwealth Games in Glasgow.
Another veteran member of the team, Jamie Dwyer, 35, was left out of the 16-man squad for the Games.
“As much as I enjoy being part of the Kookaburras and feel privileged to have been part of such an elite programme, I know that physically and mentally I can no longer commit to the programme 100 per cent and it is time to step away,” De Young said.
“I could not have asked for a better finish to my career than to win the World Cup so convincingly.”
