Our marine experience and capabilities include the delivery and construction of maritime infrastructure with varying sizes and technical complexity.

These include constructing or upgrading land-backed and verandah wharves, jetties, piers, marinas, navigational shipping aids, dolphin construction, ship access gantries, boat ramps and tug pens.

Austral Construction’s specialised marine equipment includes large self-elevating and construction barges complemented with support vessels, cranes and piling hammers, which, combined with Austral’s experience and technical capability, enables self-performance of projects of significant size while reducing construction and plant risk.
