The extended Bank of Queensland sponsorship incorporates strong electronic scoreboard branding, multiple corporate facilities, game-day activities sponsorship and Chairman's Circle match-day function entitlements at the Gabba.
Bank of Queensland has been a major support sponsor of the Lions since the 2002 premiership year.
"Bank of Queensland and the Brisbane Lions keep succeeding as partners because we're both heavily focussed on customers," Lions Chief Executive Michael Bowers said.
"We believe in delivering personal service and having an intimate relationship with our members - which is exactly the way Bank of Queensland does their business."
"Furthermore, both organisations are proud of their maroon-grown origins and we're both looking to dominate in the local Queensland and southern markets."
"We've shared a lot of business acumen, innovation and passion in the pursuit of excellence since 2002, so it's extremely gratifying to have them re-sign with us during these turbulent economic times."
"Bank of Queensland and the Brisbane Lions feel extremely confident both on and off the field sporting-wise and business-wise as we head into Season 2009."
