In recent seasons, Brookvale Oval has been regarded as a graveyard for many opposition teams, thus earning the nickname "Fortress Brookvale". Manly went through the 2011 season undefeated at its home ground, with no visiting team victorious at the ground since Round 26, 2010. In 2014, Manly held a 10–1 record at Brookvale Oval, narrowly losing to the Melbourne Storm in Round 1. In 2017 Manly didn't do well at Lottoland only winning 6 and losing 5. Today the ground has an official capacity of 23,000, although the ground is generally full at just under 21,000. In 2006, the ground saw its largest average attendance over an entire season, with an average of 15,484 patrons watching each of the club's 11 matches played there. The record crowd at the ground is 27,655, set in the final round of the 1986 season against traditional rivals Parramatta. Since the club started playing in 1947, over five and a half million spectators have visited the ground.
