How to read this view

Source of breach

Source categories reflect OAIC-published classifications. Rounded values retain an estimated state.

Affected population

Worldwide and Australian scopes remain distinct. Neither is silently substituted for the other.

Timing

Identification and notification timing retain the source’s dimension and reporting period.

Revisions

Source revisions are recorded over time. A historical value may change without creating a named incident.
