The facts
The Australian government declared West Peron an identified greenhouse-gas storage formation on 16 October. The department said this was an early step for the proposed Bonaparte project, not final authority to inject carbon dioxide. [1][2]
INPEX, the project operator, estimates the formation could store up to 443 million tonnes of carbon dioxide over as long as 35 years. This is the company's capacity estimate, not stored or captured volume. [1][2][3]
The project is about 260 kilometres offshore from Darwin. INPEX says first injection is targeted for the early 2030s, subject to regulatory approvals and commercial agreements. [2][3]
AP reported that environmental groups raised concerns about marine and coastal habitats, including threatened and migratory species; the project still needs further government licences and environmental assessment. [2]
Still unconfirmed
- The project has not received all required environmental and regulatory approvals, and no carbon injection is under way.
- The final project design, approval timetable and quantity of carbon that may ultimately be stored remain unsettled.

The primary ministerial and operator releases and AP's independent report were opened. The actual event is the 16 October storage-formation designation, not approval to construct or inject; the potential capacity is attributed to INPEX and environmental concerns are attributed to AP's reporting.
