Australia’s defense landscape in 2026 is completely dominated by the AUKUS Pillar II agreement, which focuses on "Advanced Capabilities." This has sparked a gold rush in Sydney, Brisbane, and Adelaide for startups specializing in undersea drones, quantum sensors, and hypersonic defense.
The Australian Department of Defence (ADF) has pivoted toward "Ghost Shark" autonomous systems and AI-driven battle management. This report identifies the key players in the Australian Sovereign Defence Industrial Priorities (SDIPs). These companies are not just builders; they are the "force multipliers" ensuring the Australian Defence Force (ADF) maintains a technological edge in the Indo-Pacific. Here are the top 10 verified players leading the charge in 2026.Â
1. Anduril Australia (Autonomous Systems)
While originally a US company, Anduril Australia has become a sovereign powerhouse. In 2026, they are the primary architects of the Ghost Shark Extra Large Autonomous Undersea Vehicle (XL-AUV), produced in Sydney for the Royal Australian Navy.
-
The Capability: Long-range, persistent undersea surveillance and strike capabilities.

2026 Strategic Analysis: The AUKUS Multiplier
The "essence" of Australian DefTech in 2026 is asymmetric mass. Australia knows it cannot match larger powers in hull-for-hull numbers, so it is betting big on Quantum (Q-CTRL), Underwater Autonomy (Anduril), and Rapid Sustainment (Spee3D).
