Geraldton Port Maximisation marine works

Geraldton Port Maximisation Project overview showing the new tug harbour and breakwater, Berth 1, Berth 6 extension, future Berths 8 and 9 and Seal Rocks

Mid West Ports Authority / SLR Consulting; project overview in the environmental impact assessment

Mid West Ports Authority awarded MGN Civil the surge-protection breakwater contract on 3 June 2026 and says construction will start later in 2026. The breakwater is one marine package inside the State-funded AUD 350 million Geraldton Port Maximisation Project. Ministerial Statement 1272 separately approves a wider envelope covering up to 258,000 m3 of dredging, reclamation, Berth 1 replacement, Berth 6 extension, future Berths 8 and 9 and a new tug harbour.

Project anatomy

Contract scope and delivery roles

Client / authority
Mid West Ports Authority
Delivery parties
MGN Civil Pty Ltd - surge-protection breakwater
Contract route
Mid West Ports Authority announced a direct project-specific award to MGN Civil for the surge-protection breakwater on 3 June 2026. The owner did not publish the contract value, notice-to-proceed date, rock-supply chain or subcontractors. The Western Australian Government describes PMaxP as a State-funded AUD 350 million programme. No cited source identifies construction awards for the Berth 1 replacement, Berth 6 extension, future Berths 8 and 9, or the capital-dredging packages.
Execution window
The owner says breakwater construction will commence later in 2026. A May 2026 parliamentary statement placed major construction from mid-2026 and expected the breakwater to build effectiveness through the end of 2027, but the owner's award notice gives no completion date. The 2024-25 annual report's 2028 programme target predates Ministerial approval, and no current owner notice gives package-specific completion dates for the wider marine works.
Works package
The approved proposal allows up to 258,000 m3 of dredging: 240,000 m3 of capital dredging and a once-off 18,000 m3 maintenance campaign. The environmental assessment describes a roughly 450-metre northern breakwater and new tug harbour, Berth 1 replacement with a 293-by-22-metre deck, Berth 6 extension to about 287 metres, and a future roughly 500-metre Berths 8 and 9 wharf. It anticipates about 480 piles across the berth and tug-harbour works. Dredged material is intended for on-site reuse and reclamation rather than offshore disposal, subject to suitability.
Marine interfaces
The environmental assessment places the breakwater before the main dredging works so it can reduce long-period surge inside the port and partially contain the dredging plume. That sequence links armour placement and breakwater geometry to tug-harbour operability, dredging access, reclamation capacity and the later berth layouts. The approval also prohibits capital dredging from 1 December to 28 February unless the regulator agrees otherwise and requires marine-fauna observation during piling, dredging and rock breaking.
Commercial evidence boundary
The breakwater is allocated to MGN Civil. The wider programme remains a set of separate potential packages, not one AUD 350 million contract. Market activity should be tied to owner-issued procurement, named contractors or mobilisation evidence for dredging, Berth 1, Berth 6, future Berths 8 and 9, tug-harbour jetties, survey, monitoring and material handling rather than inferred from the approval envelope.

Open this project in the Change Log

Mid West Ports awarded the surge-protection breakwater

MGN Civil became the named contractor for the first disclosed marine construction package. The announcement did not publish contract value, notice to proceed, rock source or mobilisation evidence.

Source

Ministerial Statement 1272 allowed the proposal to proceed

The approval set the 258,000 m3 dredging limit, seasonal restriction and environmental-management conditions for the wider project. It did not award the dredging or berth packages.

Source

EPA Report 1792 recommended conditional approval

The report established the assessed marine footprint, benthic impacts, material-reuse route and environmental conditions that informed the later Ministerial Statement.
