Andrews, 23, has already passed 100 games for the Lions and will likely move from vice-captain to skipper in the near-future.
Speaking on his extension, Andrews said he wouldn’t want to be playing for anyone else.
“I love the club and I’m a proud Queenslander, I couldn’t imagine playing or living anywhere else,’’ he said.
“I’ve got a great bunch of mates here, our coaches and all the support staff are first class and I have no doubt here is where I will play my best football.
“The bond we have and the determination we share to improve and have success together motivates me every single day.
“I’m thrilled to have extended my contract with the Lions and I’m genuinely excited about what lies ahead for our Club.’’
Speaking on the relationship with his coach, Andrews added his excitement to be working under Chris Fagan in their psi for a premiership.
“Fages has been terrific for me,’’ he said.
“I really enjoy catching up with him to pick his brains on all matters football and I’m happy to say I’ll be driving him mad for a long time to come.’’
General Manager of Football David Noble acknowledged Andres’ dedication to the club.
“We’ve seen Harris develop from an Academy player to an All Australian and our vice-captain in very quick time,’’ he said.
“His development is not only a testament to our coaches but also to Harris himself who’s dedication to his craft is second to none.
“To win our Most Professional Player for the past three years in a row, when you consider the calibre of some of his teammates, shows the type of player he is.’’
Andrews’ leadership was without question some of the best to come into the Lions camp according to Noble.
“His growth in this space has been especially pleasing,’’ he said.
“Like everything Harris does he has committed to becoming the best leader he can be and he has quickly become a strong deputy to Dayne Zorko.’’
Andrews is set to miss five matches after sustaining a hamstring injury, hoping the Lions make a deep run into the finals for a chance of a return.
