Open Data Catalog for Australian public data
The Open Data Catalog is the Demiton surface for browsing and pinning curated Australian government datasets. All connectors in the Public Data category - CKAN state portals, AusTender, ABR, and BOM - are managed centrally by the Demiton platform. No credentials or connector configuration required on your side.
Four sources, one catalog
Section titled “Four sources, one catalog”| Source | What it holds | System types |
|---|---|---|
| CKAN portals | State and federal open data - infrastructure registers, project datasets, spatial data | CKAN_AU |
| AusTender | Federal contract awards, tender notices, supplier data | AUSTENDER |
| ABR | ABN/ACN lookup, GST status, business entity type | ABR |
| BOM | Weather observations, forecasts, and warnings by location | BOM_WEATHER |
Each source is a platform-owned connector. Demiton maintains the API registrations - your account inherits access automatically on signup.
Connection setup
Section titled “Connection setup”No credentials or connector configuration are required. Every source in the catalog is platform-managed, so access is inherited on signup and there is nothing for a customer to set up.
Browsing the catalog
Section titled “Browsing the catalog”For every account: public data is available through the MCP server immediately on signup. Query any of the four sources through Claude or ChatGPT with no setup step.
For platform administrators: the catalog browser at /hq-platform/catalog shows all available CKAN packages across registered portals. From this surface you can:
- Browse datasets by portal, organisation, or keyword
- Pin frequently used packages to a named alias for easier workflow targeting
- Track a package - making it available in customer queries
- Untrack packages to remove them from the queryable set
Querying via MCP
Section titled “Querying via MCP”All public data sources are available through the standard MCP tools. Example queries:
- “Which civil contractors were awarded Cross River Rail packages?” - AusTender
- “Is [Supplier ABN] GST-registered? What is their entity type?” - ABR
- “What were the weather conditions at the Cunningham Gap site last month?” - BOM
- “Search data.qld.gov.au for infrastructure project datasets in southeast Queensland.” - CKAN

Section titled “What changes between tiers”| Tier | Public data access |
|---|---|
| Public | 10 ad-hoc searches per month, 3 saved watchlists |
| Baseline | Full access, correlated against your own systems and uploaded contract data |
