About Wells Marine

Wells Marine is an Australian-owned, family-operated commercial diving and marine construction company delivering specialist underwater services throughout Sydney Harbour, New South Wales and the Australian East Coast.

Built on more than 30 years of professional water experience and three generations of maritime knowledge, we have established a reputation for delivering safe, practical and dependable solutions for some of Australia’s most challenging marine environments.

From routine underwater inspections and infrastructure maintenance through to large-scale marine construction, heavy salvage and emergency response, our experienced team provides the expertise, equipment and project management needed to successfully deliver complex projects from planning through to completion.

Three Generations of Maritime Experience

Marine environments demand experience that can only be gained through years of working on and below the water.

Wells Marine has been built on decades of practical knowledge, combining traditional maritime experience with modern commercial diving techniques and specialist marine construction capabilities.

Based in the Sutherland Shire and operating from our Rozelle Bay facility, our team has an intimate understanding of Sydney Harbour and the surrounding waterways. This local knowledge allows us to respond quickly while providing practical solutions that suit each project’s unique conditions.

Specialist Marine Equipment

Successful marine projects require more than experienced personnel—they require reliable equipment designed specifically for working in demanding marine environments.

Wells Marine owns and operates a fleet of specialist marine assets, including three barges and a dedicated crane barge, enabling us to mobilise quickly for construction, lifting and salvage operations.

Owning our equipment allows us to respond faster, maintain greater control over project scheduling and provide efficient solutions for projects of all sizes.

Safety is at the heart of everything we do.

Our team consists of ADAS-accredited commercial divers operating under industry-recognised procedures and supported by Lloyd’s Register approval. Every project is carefully planned with comprehensive risk assessments, environmental controls and task-specific work methods to protect our personnel, our clients and the marine environment.

From routine maintenance through to complex underwater construction, we remain committed to delivering every project safely, professionally and efficiently.
