Houlihan made his debut in Round 4, 1997 with the Geelong Football Club against Essendon. He wore the number 3 guernsey. He was drafted as a compensatory selection (second overall) in the 1995 pre-season draft from the Murray Bushrangers at the age of 16. He actually started out as a jockey but a growth spurt put an end to that and he turned his attention to Australian rules football, playing senior football for Corowa-Rutherglen at sixteen. Houlihan made a name for himself as a talented half forward, kicking five goals in several games. He managed 14 games in his debut season but just one the following year after a series of injuries. He played two games early in 1999, having little impact. He returned to play all the final eight games and established himself in 2000, playing 22 of 23 games and a top 10 best and fairest finish. But after playing 12 of the first 13 games in 2001, his form fell away, playing just two more games and he was then delisted.
Richmond: 2002–2004
Houlihan was drafted by Richmond and resumed his career there in 2002, wearing the number 44 guernsey. He played the first 12 games in 2002, including a three-goal effort in Round 11 but only managed one further game, spending most of the remainder of the season in the Victorian Football League (VFL). He played 16 games in 2003, including four and five goal efforts. A hamstring injury kept him out for most of 2004, returning late in the season for four games but incoming coach Terry Wallace decided Houlihan did not fit in with his plans.
Post-AFL career
Houlihan continued to play with Richmond's VFL affiliate Coburg in 2005. At 26 years of age, Houlihan decided that his career was already over and he ruled out playing AFL football again. He instead returned to his earlier interest in horse racing, hosting a horse-racing tips show with Brett Phillips and Nick Evans on radio station SEN 1116 and training jockeys in diet and fitness. In 2007 he chose to take some great advise from mentor and now business partner Bruce Armstrong and start his own promotional merchandise business called CorpEdge Marketing. He is currently playing football with Old Scotch Football Club.[2]
