About this Dataset

The AU Modern Slavery Register API provides structured access to modern slavery statements lodged with the Australian Border Force under the Modern Slavery Act 2018 (Cth). Entities with annual consolidated revenue of AUD $100 million or more must lodge a statement each year disclosing their modern slavery risks and the actions taken to address them.

What is a modern slavery statement?

A modern slavery statement is a public document lodged by a reporting entity describing the risks of modern slavery in its operations and supply chains, and the steps taken to assess and address those risks. Statements cover forced labour, child labour, debt bondage, human trafficking, and other forms of exploitation. Joint statements may be lodged by a parent entity covering multiple subsidiaries — these appear as a single statement with multiple ABNs.

Who must lodge?

Australian entities and foreign entities carrying on business in Australia with annual consolidated revenue of AUD $100 million or more must lodge annually. Smaller entities may lodge voluntarily. Statements are due within 6 months of the entity's financial year end — most entities have a 30 June FYE, making statements due by 31 December each year.

Update frequency

The Tech Compass pipeline ingests a fresh snapshot from the Modern Slavery Register quarterly (January, April, July, October). Statements trickle in year-round and accumulate via unique statement_id upsert — existing statements are updated if amended.

Data lineage

Every response includes a data_lineage block with source, source_attribution, license, and retrieved_at for audit purposes.

Licensing

Modern slavery statements are public records lodged under the Modern Slavery Act 2018 (Cth). The register is maintained by the Australian Border Force and is freely available at modernslaveryregister.gov.au.
