Habitat Enhancement Structures (HES) developments are increasing in Australia and worldwide providing many benefits to the environment and different user groups. With this rapid growth there are still large knowledge gaps evident in relation to HES. This project investigated the application, needs, benefits and costs of HES as well as cost-effective monitoring methods. Post graduate students collated international literature on all aspects of HES and project managers consulted with industry and the community to identify potential applications to different sectors. Different monitoring methods were also tested on the South West Artificial Reef Trial in Geographe Bay, Western Australia. Information and data collected was analysed, reviewed and processed to create an easy-to-follow guide for groups aiming to invest in HES. This is one of the first guides to clearly outline the HES development process in Australia. The project also developed Reef Vision, a world first, cost-effective HES monitoring method that uses citizen science and Baited Remote Underwater Video systems


1. Identify what HES are currently available throughout the world and what benefits each type may have for recreational and commercial fishing as well as identifying the benefits for aquaculture and the environment.

2. Identify how various HES design might provide benefit to the WA seafood sector and community and determine applications and locations for the most effective return on investments.

3. Determine cost effective methods to monitor HES developments using easily available materials and data collection by community and industry groups.

4. Investigate cost effective reef, site selection, approvals, construction, deployment and monitoring strategies for business, industry and community groups wanting invest in HES.
