Jaques retired from first-class cricket last year and joined New South Wales as an assistant coach for the 2014-15 season. He played 11 Tests for Australia and averaged 47.47, but his later career was affected by back injuries that contributed to his not playing more matches for his country.
"Queensland were always amongst my toughest opponents when I was playing, but also good company off the field, and I am thrilled about the prospect of now playing a role in that culture," Jaques said. "It goes without saying that I am grateful to Cricket NSW for giving me the chance to move into coaching last year and I will always appreciate their support over my career.
"But the challenge of taking on my first senior coaching role with the Bulls is incredibly exciting and it is a journey I am very eager to begin. I was able to combine coaching and playing at grade level with Sutherland before taking on the pathway and assistant coach roles with Cricket NSW and the Blues and it has always been where I wanted to go with my post-playing career.
"I have good memories of the Gabba. I made my first-class debut in a game where the Bulls had NSW under the pump, and later representing my country in a Test match there where I was able to score my first Test century. The Bulls have an exciting squad, with probably the most potential of any group in Australia, and I am sure there will be many rewarding opportunities awaiting our players in the future."
Queensland's high-performance manager Brett Jones said: "He was still achieving at a high level in first class cricket mid-way through 2014 so he is very much a person who is attuned as to what is required to be successful as a player in the Sheffield Shield and beyond. Phil is comfortable in a high-performance environment and we will certainly be working hard to support him."
