This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2023 project 3.7 – Identifying and overcoming barriers to coastal and marine habitat restoration and Nature based Solutions in Australia. No data outputs are planned for this project.

--------------------

There is an increasing need for coastal and marine restoration around Australia to help address habitat and biodiversity loss, water quality decline, invasive species impacts, and coastal inundation and erosion; and to identify blue carbon opportunities. However, broader uptake of restoration and nature-based solutions in Australia is constrained by policy and legislative barriers, limited adoption within engineering practice, and insufficient inclusion of Aboriginal and Torres Strait Islander peoples in project design and delivery.

This project examined barriers and opportunities for scaling marine and coastal restoration and nature-based solutions across three themes: (1) regulatory and permitting pathways; (2) engineering sector adoption, and (3) Aboriginal and Torres Strait Islander inclusion and co-design. The approach built on earlier work through Marine and Coastal Hub Project 1.6 ( https://www.nespmarinecoastal.edu.au/project/1-6/) which identified a clear need for coordinated, landscape-scale restoration and greater support for nature-based approaches.

Research reviews of approval and permitting processes were conducted in Queensland, New South Wales, Tasmania and South Australia, with a focus on oyster reef restoration and tidal reintroduction for wetland restoration. Consultation was undertaken with Commonwealth and state agencies, the national Wetland and Aquatic Ecosystems Task Force, restoration practitioners, non-government organisations, engineering and environmental consultancies, and Indigenous groups involved in restoration activities.

Workshop and consultation findings were translated into practical guidance and framework materials for governments, practitioners and restoration proponents. These outputs provide a basis for clearer approval pathways, greater confidence in nature-based solutions within coastal engineering, and more inclusive restoration planning with Aboriginal and Torres Strait Islander peoples.
