Oar burst onto the international scene after joining Brisbane Roar FC as a rising star of the local leagues at the start of the 2008-09 season.
His Hyundai A-League performances with the Roar in season 2009-10 saw him voted the NAB Rising Star award for the Best Young Player in the country.
An extraordinary six months continued as Oar was selected for his Socceroo debut against Indonesia in March 2010. He took his chance to shine, dominating down the left-wing and he was instantly catapulted into World Cup contention.
He signed a contract to join Dutch side FC Utrecht and spent two months training in Holland before being selected in the preliminary squad for the 2010 World Cup.
Oar didn’t make it to South Africa but would later become a key member of the Socceroos squad on the road to Brazil.
As the Socceroos qualification for the World Cup neared its crescendo, Oar scored a goal against the run of play against Japan to put Australia up 1-0 in Saitama.
The Socceroos conceded a goal late but the draw would eventually help Australia book their tickets to Brazil, where he played in every game.
Oar was part of the historic Asian Cup winning squad of 2015 though his game-time was restricted to one appearance off the bench.
But the Dutch-based winger, who seems likely to exit Utrecht at the end of the season, remains a potent attacking weapon and in his early 20s we can expect him to continue to torment opposition defences as the Socceroos look to qualify for World Cup 2018 and Asian Cup 2019.
