Queensland is split into 11 Sub Chambers based on geographical areas around the state.  Each Sub Chamber supports the Agricultural Societies within it's boundaries and elects a representative to the QCAS Board. 

Wherever possible, for collaboration in respect of show dates and other matters, Sub-Chambers of Societies are formed. Each Sub-Chamber has the power to make rules for the management of its own affairs provided such rules are not inconsistent with the Rules or decisions of the Chamber or the Board.

Each Sub-Chamber is responsible for implementing proposals referred from the Chamber or the Board.

Each Sub-Chamber is represented on the QCAS Board by: in the case of a Sub-Chamber that represents less than 14 Members, 1 Delegate, and in the case of a Sub-Chamber that represents 14 or more Members, 2 Delegates.  An alternate Delegate will be elected who may replace the Delegate at a meeting of the Board if that Delegate is unable or unwilling to attend a meeting of the Board.

Delegates must be members of a member Society of the Chamber.
