Career
Born in Sydney, McNamara was a right-handed bowling all-rounder, and played for the Australian national under-19 cricket team before playing for New South Wales. In 1999, at the end of his career, he also appeared in a single limited-overs match for the Middlesex Cricket Board. McNamara was an all-rounder for the NSW Blues in Australian domestic cricket for over a decade.
When without injuries he was a regular selection for the Blues, particularly in one-day teams.
As a medium pace bowler, his strength was his ability to worry batsmen with a combination of accuracy and unpredictability. Office a relatively short run, he combined good line and length with difficult to read "change-up" balls, swing and seam.
McNamara was the "man of the match" in his first List A match for New South Wales. McNamara retired from interstate competition at the end of the 1999–2000 season.
After his retirement from cricket, McNamara went to work for, becoming their executive director of cricket.
