Groups
What this subdivision covers
ANZSIC subdivision 30 is the middle layer between the broad division and the more specific groups. It is useful when you want to understand the section of the economy without jumping straight to the final class code.
This is also where confusion often appears. Similar business types can sit in nearby groups, so using the subdivision page first makes the boundary clearer before you narrow the match further.

Frequently asked questions
What does subdivision 30 add?
Building Construction narrows the broad division into a more specific industry family. It is the level you use when you need more precision but are not yet at the final class.
Can I view the class pages directly from subdivision 30?
Yes. This page now shows both the groups and the class pages nested under them, so you can move straight to the final four-digit ANZSIC class when the subdivision is already correct.
Is the subdivision code the one used on forms?
Usually not. Most operational forms use the class-level code. The subdivision page is mainly for navigation and understanding the hierarchy.
How to use this page
If you know the division but not the exact group, this is the right stepping stone. It keeps the hierarchy readable and stops you from guessing the four-digit class too early.
For code selection work, move from subdivision to group and then confirm on the class page before you rely on the result for registration, reporting or taxonomy mapping.
