Project Status


Onslow Marine Support Base (OMSB) is a strategic marvel nestled in Onslow, Western Australia. NAIF financing played a pivotal role in expediting the project's comprehensive scope, making an immediate impact and unlocking Onslow's potential.

About Onslow Marine Support Base

The Onslow Marine Support Base is a pivotal facility catering to the needs of diverse offshore industries, with a primary focus on the oil and gas sector. 

Operating as a vital port and logistics hub, the support base serves as a central point for the transportation of personnel, equipment and essential supplies to and from offshore facilities. 

Its comprehensive range of services ensures seamless operations and plays a crucial role in bolstering the activities of the offshore energy sector within the region.

Project Overview

The OMSB facility upgrade encompassed several key components, such as a wharf, training wall upgrade, and expansion of the inner/harbor channel. This expansion project involved capital construction for both the channel and turning basin.

This multi-user facility serves as a comprehensive resource, offering chandlering services, heavy lift capabilities, reverse logistics support, refueling options, transportation solutions, freight services, and emergency assistance. Its primary purpose is to provide essential support to onshore and offshore industries operating in the middle and southern regions of the Carnarvon Basin.

How We Helped

NAIF’s support helped to unlock the economic potential of the whole project by overcoming current depth limitations on the range of vessel serviceability.

All vessels supporting the operations of the offshore oil and gas industry in the region will now be able to access the new base, providing greater efficiency.

NAIF financing was integral to the immediate delivery of the full project scope (accelerated by 3-5 years). NAIF used its risk appetite to complement private lender National Australia Bank.

Public Impact

The Onslow Marine Support Base project is expected to yield substantial economic benefits for Western Australia, with a projected $100 million benefit over a 10-year period. This includes a notable 45% increase in the local Gross Regional Product compared to the figures from the 2011 census. These economic advantages are also expected to extend to the broader Onslow and Ashburton communities.

In terms of employment, the project estimates that it will create 61 jobs during the construction phase and 166 jobs during its operational phase. This represents a significant boost to the local workforce and economic activity.

Furthermore, the facility is anticipated to deliver significant advantages in terms of productivity, time efficiency, and fuel savings, ultimately reducing costs for local operators and mitigating operational risks. Additionally, it will help retain and capture services that might otherwise be outsourced overseas.

NAIF has been instrumental in allowing the OMSB project to progress far quicker and unlock the strategic location of Onslow, which will provide efficiencies that will promote jobs and further opportunities to the state of WA.

Traditional owners of this land

The Thalanyji people are the Traditional Owners of the land on which OMSB is located. The Thalanyji people traditionally inhabited lands that cover a portion of the south-western Pilbara region, extending from the Ashburton River coastal plain, towards Tubridji Point in the south, and across to the Yannarie River. 

Thalanyji country is geographically diverse and includes the coast, coastal plains, rivers and streams, ranges and salt lakes. The Thalanyji people’s Native Title claim, which covers an area of 11,120 km², was determined and recognised by the Federal Court in 2008.
