Riverside Marine

What Riverside Marine does

Riverside Marine is a 100-year-old Australian marine operator headquartered in Newstead, Brisbane, providing diversified marine services through five wholly-owned subsidiaries: Rivtow Marine (harbour towage operating the largest tug fleet in any Australian port at Port Hedland with 17 tugs, and sole service provider for BMA at the Port of Hay Point), Riverside Industrial Sands (dredging and the largest construction sand supplier within the Brisbane City region), Magnetic Island Ferries (365-day drive-on/drive-off and walk-on passenger ferry service connecting Townsville and Magnetic Island for 30+ years), Riverside Oceanic (three specialist vessels serving marine research, hydrographic, and offshore energy markets), and Riverside Ship Management. The company employs 101-250 people and operates dedicated facilities across Queensland (Brisbane/Newstead, Hemmant, Hay Point, South Townsville) and Western Australia (Port Hedland). Revenue is generated through four distinct streams: managed-service harbour towage contracts with major ports and mining companies, one-time dredging and sand supply transactions with construction buyers, transaction-fee ferry services to tourism and local communities, and professional-services vessel charters to government research institutions and offshore energy customers. Pricing is negotiated B2B and not publicly disclosed. Effective 31 March 2026, Bhagwan Marine Limited (ASX: BWN) acquired 100% of Riverside Marine Holdings Pty Ltd, integrating the 95+ year family-owned Campbell business into an ASX-listed marine solutions group while retaining the existing sub-brand portfolio.
