The final stage of the Hillarys Boat Harbour jetties A, F, G, H and J replacement was completed by Western Australia's Department of Transport in April 2024. The project demolished and replaced five end-of-life jetties with low-maintenance floating infrastructure connected to a realigned 3.5-metre-wide central walkway and accommodating 115 pens. Tenders WA places the works under DOT409421RFT with Global Trade Sales (Gambetta Holdings Pty Ltd). The 2023-24 annual report describes the project as AUD 10 million and records approximately 320 tonnes of steel piles, 51 tonnes of aluminium pontoon frames and 1,985 square metres of pontoons.

Project anatomy

Contract scope and delivery roles

Client / authority
Western Australia Department of Transport, now Department of Transport and Major Infrastructure
Delivery parties
Global Trade Sales (Gambetta Holdings Pty Ltd), referred to by the owner as GTS Australia - confirmed design-and-construct contractor under DOT409421RFT, WA floating-module, fendering and aluminium-frame suppliers - local manufacture confirmed but organizations not named, Piling, services, demolition and other lower tiers - organizations not named in the reviewed records
Contract route
Tenders WA records DOT409421RFT as an Open Advertisement one-off works contract with 14 submissions, awarded on 29 April 2022 and carrying a final expiry date of 21 December 2023. The contract combined Hillarys with Fremantle Jetty 3 and currently publishes AUD 15,582,213 original estimate, AUD 14,464,405 revised estimate and AUD 14,448,283 actual expenditure.
Execution window
The common contract period ended on 21 December 2023. Transport WA's annual report states that the Hillarys final stage completed in April 2024. The difference between the contract expiry field and the final-stage completion statement is an evidence boundary; public records do not explain whether it reflects staged completion, closeout, defects, owner work or contract administration.
Works package
The Hillarys site scope comprised demolition and removal of jetties A, F, G, H and J; a realigned 3.5-metre-wide central floating walkway; design, supply and installation of low-maintenance floating boat-pen systems; piling; power, water, firefighting and CCTV services; and capacity for 115 pens.
Marine interfaces
The replacement had to preserve penholder access and improve pedestrian movement for Rottnest Island ferry passengers and service vehicles inside an active harbour. The completed system combines piles, pontoons, fendering, aluminium frames, services and the central walkway, but public sources do not expose staging drawings, temporary access, pile installation methods, commissioning procedures or as-built service records.
Commercial evidence boundary
The 2023-24 annual report calls Hillarys an AUD 10 million project and says 84% of contract spend was in metropolitan WA, with the balance interstate and overseas. The 2022-23 annual report estimated total capital cost at AUD 10.014 million, up from AUD 9.464 million in earlier reports. These project and localisation fields cannot be used to allocate or reconstruct the common contract's final expenditure.
