What Commercial Diving Services does
Commercial Diving Services Pty Ltd (CDS) is an Australian privately held, family-owned commercial diving company founded in 1955 by Neil Johnson and now operating across three generations of the Johnson family. Headquartered in Sydney, the company provides a comprehensive suite of underwater services to government agencies, ports, shipping operators, water utilities, and corporate clients across Australia and New Zealand. Named customers include Roads and Maritime Services, Water NSW, Hunter Water, NSW Ports, Port of Newcastle, and Shell, indicating a mix of government infrastructure and enterprise energy/logistics engagements.
The company's core services span ship in-water services (class surveys, hull inspections, propeller polishing, anchor maintenance, bio-security, and MPI inspections), inland diving (dam, bridge, wharf, potable water reservoir, and pipeline inspections), and underwater maintenance and construction (welding, cutting, drilling, pressure blasting, concreting, anode installation). Specialised services include deep diving, ROV operations, marine salvage, non-destructive testing, and crane services. The technology platform comprises a fleet of 500+ specialised plant items including dive boats, work punts, transport boats, modular barges, elevated work platforms, silt curtains, oil booms, and air lift bags. The firm operates dedicated sub-brands: CDS Drones (ROV drone division), CDS Cranes (TIDD 25t articulating crane with Slew Safe system), and MICRO Dredge (sediment removal), with recent online shop sales of SpilMax environmental products and branded lifestyle merchandise.
The business model combines professional services (project-based diving contracts with multi-year frameworks), equipment hire (daily/project rates for boats, barges, and platforms), and retail e-commerce (hardware spill containment products and merchandise). Pricing is primarily quote-based for services, with unit pricing for online shop SKUs ranging from $24.99 (caps) to $6,868.40 (large containment bunds). Distribution is direct-to-customer via 24/7 phone, project-based sales, and a self-service online storefront, supported by SEO, social media, and email marketing. The company holds multiple regulatory certifications (Lloyd's Register, ABS, DNV GL, JASANZ, ISO 9001, ISO 14001, AS/NZS 4801, AS/NZS 2299.1.2015) that function as procurement gating requirements for maritime and government clients. CDS does not operate outside the Australian/NZ region, has no disclosed external funding, and remains under Johnson family ownership with no parent company or institutional investors.
