Onslow Marine Support Base-Web

Onslow Marine Support Base

Investment Decision September 2017. Constructed


Marine supply base facility, including wharf, training wall upgrade and inner / harbour channel expansion (capital construction of channel and turning basin).

NAIF’s Value

Unlocked 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 great efficiencies.

NAIF financing was integral to 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 waterway works financed by NAIF (without requiring security which was not available given non-exclusive use of channel).

Indigenous Engagement
