Coastal management
Coastal environments are a complex and challenging place to work and need clear understanding, along with the effective integration of coastal and river processes. We provide specialist assessment of physical processes associated with the coastline, estuaries, floodplains, and waterways to inform strategic planning and design for current and climate-changed conditions.
Coastal planning
Our work in coastal planning involves managing land use and development in coastal areas to balance environmental and cultural conservation, economic activities, and community needs. It considers both short- and longer-term planning, including consideration of erosion and inundation associated with rising sea levels. Strategies include zoning, sustainable infrastructure, and disaster risk reduction, ensuring resilience and sustainable development while protecting fragile coastal ecosystems and resources.
Coastal engineering
We take a nature-based, systems-thinking approach to coastal engineering, focusing on solutions that work with natural processes rather than against them. Our team has extensive experience delivering projects from concept design through to detailed design of coastal protection measures such as dune stabilisation systems, beach nourishment, revetments and seawalls. We apply advanced numerical modelling to assess both short-term and long-term coastal impacts and shoreline change, allowing us to develop robust designs that work with the dynamic coastal conditions. By combining deep scientific knowledge with practical engineering expertise, we offer clients tailored, cost-effective, and nature-based focused solutions to complex coastal erosion and inundation challenges.
Coastal processes and geomorphology
The coastline is a highly dynamic setting, and we provide clear, specialist advice to inform management within this challenging environment. We undertake assessments of coastal processes, including sediment dynamics, trajectory of landscape change, and implications for management and mitigation options.
Industry leadership
Our industry leaders are known for their deep expertise and knowledge in their field. They bring a thorough understanding of industry trends, technologies and best practices.

Phebe Bicknell
Phebe is an environmental engineer and scientist specialising in coastal, marine, and estuarine processes. She has extensive experience in monitoring, modelling and analysing these dynamic and complex environments and their management.<br><br>Based in Victoria, Phebe has over 15 years of experience working with state and local government agencies on a diverse range of technical and strategic projects, from catchment through to coast. She assists land managers, councils, and communities in understanding and mitigating coastal hazard risks through tailored technical analyses and longer-term planning. From engineering design, hazard adaptation planning, risk assessment and strategic decision making, she has led and contributed to many coastal and estuarine studies across Australia. Several of these projects have been influential in advancing coastal hazard adaptation planning in the industry, informing Victoria’s state guidance and progressing its ongoing implementation.<br><br>With a focus on effective communication, Phebe is passionate about making technical information more accessible. She is dedicated to increasing knowledge and awareness of coastal hazards, adaptation planning, and climate change. Much of her work involves collaborating with coastal communities, designing and facilitating tailored community and stakeholder consultation to inform decision-making and achieve positive environmental outcomes.

Adam Brook
Adam is Business Area Lead – Coastal, bringing a wide range of coastal and marine management experience.<br><br>Adam is an enthusiastic professional with over 20 years’ experience in design, construction and local government engineering, working in various locations including Australia, Hong Kong, Vietnam and UAE. His coastal engineering experience includes design of nature-based solutions, artificial reefs, beach nourishment, breakwaters, seawalls, wharfs, jetties, pontoons, slope stabilisation, dredging and reclamation, as well as practical site experience. Adam has also been involved in wave and coastal modelling for numerous projects.<br><br>Over the last 10 plus years Adam has worked on numerous Coastal Hazard Adaption Strategy’s (CHAS) and Shoreline Erosion Management Plans (SEMP) throughout Queensland and many other management plans and strategies in the other states.<br><br>Adam’s skills allow him to work through the full life cycle of projects from planning and design through to gaining approvals, then undertaking detailed design for construction, maintenance or repair and supervising and certifying the construction works.
