The SOS Structure is defined only in census years. It contains three hierarchical levels, comprising in ascending order: CDs-SOS-S/Ts.
In this structure, CDs aggregate to SOS and SOS aggregate to S/Ts without gaps or overlaps. Consequently, the structure covers all of Australia.
The Sections of State Structure determined following the 2006 Census are listed in the publication Statistical Geography: Volume 1 Australian Standard Geographical Classification (ASGC), 2006 (cat. no. 1216.0). This list provides:
