The Bach Society of Queensland Inc. was formed in 1971 at the instance of Nancy Weir, who became the society's distinguished patron. The aims and objects of the society are "to promote and encourage the performance and study chiefly of the work of Johann Sebastian Bach, his family, his contemporaries, and his precursors".

The main arm of the society is the Bach Choir which was formed in 1972 as an additional medium for the society's purposes. The choir presents several concerts each year, and in the past, these have included works by J.S. Bach, Vivaldi, Mozart, Scarlatti, Handel, and many other well known composers, as well as lesser known works. These concerts provide a valuable opportunity for young musicians to obtain experience in the performance of Baroque music, and also allow audiences to hear many works seldom performed in Brisbane.
