He is one of the greatest talents Australian football has produced in the last two decades and was one of the most skilful players playing their trade in the now-defunct National Soccer League. Halpin represented many NSL clubs and won championships with Sydney Olympic and Perth Glory. He also played with Newcastle United and at Perth Glory with his brother Scott Halpin. He has played with Sydney United and Marconi in the NSW competition and wore the No 10 shirt. Halpin was most famous for his outstanding technical ability with the ball and vision in the mid-field. For the Socceroos, Halpin managed 12 caps and 3 goals. This was seen by many as a waste as he is rated as one of Australia's finest footballing talents.
He is currently employed by the Kings School in his role as Director of Football. Halpin recently held the role of player/coach in the Northern NSW NBN State Football League with the Toronto Awaba Stags FC before moving to Edgeworth Eagles FC where he will continue playing whilst also overseeing youth development for the club in the upcoming 2010 season. Halpin recently joined the coaching staff at Mongo Football which is a Football Academy on Sydney's North Shore and is based at Macquarie University.
