DATA FOUNDATIONS
The Data Layer
The Group Runs On.
Market, supply, planning, material and carbon data — built to back the group's own decisions, suburb-level, Australia-wide.
We don't run a data storefront. These are the datasets our companies plan, price and build against — and the same foundations we open to government and research partners through collaboration.

These datasets serve the group's own projects first. Government and research partners work with them through collaboration. See how partnerships work →
How Data Moves In A Partnership.
When a collaboration includes data sharing, these are the three ways we deliver it.
REST API
JSON / GraphQLBest for: partner platforms and pilot integrations.
- → Standard REST endpoints (JSON responses)
- → Authentication via secure API key
- → Rate limits scoped to each collaboration
- → Sandbox available for testing
