Turning professional in 1998, Healey has won 3 doubles titles.
In 2006, he earned a wildcard to the Australian Open, making the 3rd round, where he was defeated by Russian Nikolay Davydenko in four sets. Later that year, he made it to the 3rd qualifying round at Wimbledon, where he was soundly defeated by Robert Kendrick. As of 26 June 2006, Healey was 199th in the ATP rankings.
In January 2007 Healey substituted for Mark Philippoussis after the latter sustained a knee injury during the Hopman Cup in Perth. He lost a close match against American Mardy Fish (7–5, 7–5), but then teamed with Alicia Molik to win the mixed doubles (6–4, 7–5) against Fish and Ashley Harkleroad.
Nathan relocated to the Philadelphia area to be close to his family in 2010 and started working with local juniors. He spent the Australian summer back in his homeland with his cats and won numerous singles and doubles titles during his "vacation". Nathan was drafted in 2011 to play for the Philadelphia Freedoms of the WTT..
