Raised in Chipping Norton, Brendan began playing football with local side Chipping Norton FC before moving around through various state league sides until catching the eye of youth representative teams.
Signing with the Australian Institute of Sport in 2009, the defender with Irish heritage was soon promoted to the institute’s National Youth League team.
Following a great season in the NYL Brendan, then 18, was picked up by Hyundai A-League outfit Melbourne Heart where he stayed for two seasons until a move to Asia came calling in the form of K-League side Seongnam Ilhwa Chunma.
During this time Brendan represented Australia on several occasions being selected for the U17, U20 and U23 sides, wearing the Captain’s armband for the U17 Joeys.
Injury interrupted his time in Korea and on 26 June 2014 the commanding defender returned to his home town to sign with the Western Sydney Wanderers, making his Red & Black debut against Guangzhou Evergrande in the AFC Champions League Quarter Final.
After an impressive first season earned him a two year contract extension, Brendan started 2015/16 off in the best way, scoring his first Wanderers goal against Palm Beach Sharks in the Westfield FFA Cup Round of 16.
Hamill went on to make over 20 appearances in season 2016/17 and earned himself another contract extension that will see him don the Red & Black for another two seasons.
