Review of offshore anchoring

Overview
Why is this project important?
NSW’s major ports are important trade gateways to the world.
Before entering these ports, many large commercial ships anchor in deep water offshore. We don’t know how large ships anchoring on NSW’s seabed habitats affect these habitats or the fish they support.
This project is studying the impacts of anchoring activity of large ships.
What we learn will help guide the actions we take to minimise any negative impacts.
What are we doing?
We are leading a world-first study on the impacts of large ship anchoring that can sometimes impact rocky reef habitats in temperate regions (that is, between the tropics and the poles).
The study uses a remotely operated vehicle to observe the effect anchoring has on the animals (such as sponges, sea squirts and fishes) that live on or near deep reef habitats.
We are working with stakeholders and project partners to find ways to minimise the impacts of large ships anchoring on seabed habitats along NSW’s metropolitan coastline.
What have we achieved so far?
Our research has shown that large ships anchoring offshore of Port Kembla reduce reef biodiversity.
We have run workshops with industry leaders, academics and government agencies. The aim of the workshops is to develop better ways to protect marine biodiversity based on our research.
In partnership with the Port Authority of NSW, we have developed designated anchorages offshore of Port Kembla Harbour. The designated anchorages:
- don’t allow anchoring on relatively pristine reefs
- limit anchoring other reefs to allow them time to recover.
