Duratec Secures Major AUKUS Wharf Contract
Duratec (ASX:DUR) landed the biggest contract in its history. The Department of Defence has awarded the Duratec Ertech Joint Venture a A$281m deal to upgrade the Diamantina Wharf at HMAS Stirling in Western Australia. Shares jumped 6.37% on Wednesday following the announcement, before settling at A$2.82 as investors took stock of what the contract means for the company’s growth trajectory. The joint venture is a 50:50 partnership between Duratec and fellow Perth company Ertech.
On the surface, this looks like a big contract win for a small company. But the more important story is what it signals. Duratec is no longer hovering around the edges of Australia’s AUKUS submarine program. It is now one of the program’s key construction partners.
What are the Best ASX Stocks to invest in right now?
What the A$281m HMAS Stirling Contract Actually Means
HMAS Stirling is the naval base Australia is preparing to host US and UK nuclear-powered submarines from late 2027 under the AUKUS agreement. To make that happen, the base needs significant upgrades, and the government is expected to spend around A$8bn at the site over the coming years. This contract is one of the first major steps in that process.
Work is already underway. Early site works and long-lead material orders have been running since January, and with the final design now approved, the main 24-month construction phase is beginning. Total project value is expected to reach just under A$300m once all works are complete.
What gives us confidence that this is not a one-off is Duratec’s history at the site. The company has worked at HMAS Stirling since 2015. In defence contracting, that kind of track record matters enormously. Procurement teams do not hand billion-dollar programs to unfamiliar contractors. Duratec is a known and trusted partner on site, and that incumbency is a genuine competitive advantage as the AUKUS spending ramps up.
The company is also the first construction company in Australia to earn accreditation for nuclear sector construction work, a credential that puts it ahead of almost every competitor when defence tenders come to market. This puts it in a strong position to keep winning contracts as the program grows beyond this initial wharf project.
Duratec’s Financial Position and Growth Outlook
The business behind the contract wins is in good shape. Revenue hit a record in FY25, margins are improving as more high-value defence work flows through, and the company holds a healthy cash position with no balance sheet stress. Management also recently lifted the fully franked dividend, which reflects genuine confidence in the company’s cash generation.
The forward pipeline is substantial. There is a large body of work being tendered across defence, mining, and energy, and the AUKUS program alone represents years of potential future contracts.
The Investor’s Takeaway
Duratec shares trade around A$2.82, and the stock has had a very strong run over the past year. The valuation is no longer cheap, and we believe the market has already priced in a meaningful share of the AUKUS opportunity.
For investors already holding DUR, the long-term thesis remains intact and there is little reason to sell. The AUKUS tailwind is real, the company is well placed, and the fundamentals support staying the course.
For new investors, the honest answer is that patience may be rewarded. A pullback from current levels would offer a more comfortable entry point. That said, if the AUKUS contract pipeline keeps delivering, the wait may not come. The story here is compelling, and Duratec has earned its place in it.
