Pennant Hills, due to its wide array of sporting facilities, plays home to a large number of sporting organisations. These organisations include the Pennant Hills Football Club, which was established in 1957, and the Pennant Hills Demons AFC, which has seen nine players go on to compete in the AFL. Although the Ern Holmes Oval is no longer the home ground of the Demons premiership team due to its size, many of the club's junior teams still compete in Pennant Hills.
