The LGA Structure shows the relationship between LGAs and SLAs. This relationship can be one LGA to one SLA or one LGA to many SLAs.
The LGA Structure is separate from the Main Structure because:
- Unlike spatial units in the Main Structure, LGAs do not cover the whole of Australia
- Unlike SLAs which aggregate to form SSDs and SDs, some LGAs do not wholly fit within an SSD and an SD (e.g. Mid-Western Regional Area in New South Wales).
