Reports and research

NQBP have spent more than three years undertaking detailed studies and engaging with a range of stakeholders to understand the source of natural sediment accumulation and appropriate removal and placement options at the Port of Hay Point.

These assessment reports have been developed in consultation with a range of professionals and stakeholder groups. For more detailed information on any aspect of this assessment you can view the reports and associated appendices below.
