Carpentaria Coast

This assessment summary component has changed from 2011.

The Gulf of Carpentaria division was renamed the Carpentaria Coast division.

The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting cycles.
