What this feed shows
Every week, ABN Signal compares fresh data from the Australian Business Register against the previous snapshot. When a field differs — a name, a status, a GST registration — we flag it here.
This feed covers all tracked fields in one place. If you only care about a specific type, try the ABN Status, GST Status, or Name Changes feeds instead.
What types of changes are tracked
We monitor more than ten fields on each ABN record, including:
- ABN status — whether an entity's ABN moved between active and cancelled.
- GST status — whether GST registration was added, removed, or changed.
- Entity and business names — trading name additions, removals, and updates.
- Location and other fields — postcode, ACNC status, charity type, and more.
For a full explanation of how each field works, see the glossary.
How to read these entries
Each entry compares two weekly snapshots of the same ABN record. You will see the entity name, ABN, what changed, and when we spotted the difference. The old value appears with a strikethrough, followed by the new value.
Keep in mind that the actual change at the source may have happened at any point during the preceding week — what you see here is the moment we identified it, not the moment it occurred.
How often is this updated
ABN Signal refreshes its data weekly. After each sync, changes appear automatically in this feed. You can check our methodology for details on how the comparison works and what a record update means.
