Halliday Engineering is a fifth-generation Australian maritime engineering company delivering specialist mechanical fitting, propulsion and heavy mechanical services to the commercial marine sector. With over 170 years of heritage supporting Australian vessels, Halliday provides sovereign, workshop and on-vessel capability aligned with the needs of vessel operators, ship repair facilities, ports and marine asset owners across the national fleet.

Our core mechanical fitting services cover a broad range of critical marine assets including valves, pumps, gearboxes, winches, capstans, watertight doors, hatches and gangways, supporting both planned maintenance and urgent rectification works. As propulsion system specialists, we regularly remove, survey and reinstate shafts, couplings, rudders and bearings, undertaking straightening, repair, remanufacture and precision alignment prior to installation to ensure optimal performance and reliability.

Halliday combines experienced field service teams with in-house heavy fabrication and machining capability to deliver end-to end mechanical sustainment solutions across commercial vessel classes and marine infrastructure. Our focus is on minimising downtime, improving asset longevity and providing practical, high-quality engineering support in operational marine environments.

Aligned with the objectives of the Australian Commercial Marine Group and the broader commercial maritime industry, Halliday Engineering offers responsive, Australian-based mechanical and propulsion expertise that strengthens the capability and resilience of Australia’s commercial marine fleet.
