Space is no longer a benign backdrop for Australian defence planning. It is an operating domain where satellites are tracked, threatened, and—increasingly—defended. The startups building Australia’s response are not waiting for a formal doctrine to emerge; they are shipping hardware, winning allied contracts, and closing sovereign funding rounds at a pace that outstrips policy cycles.
Seeing the Invisible: HEO and Non-Earth Imaging
Sydney-based HEO has carved out a niche that few governments can afford to ignore. The company designs and manufactures satellite-mounted cameras and AI-enabled software that photograph and characterise other objects in orbit—a field known as Non-Earth Imaging (NEI). HEO’s platform directs cameras, stitches together multiple images, and produces detailed composite assessments of satellites and debris, turning raw imagery into intelligence.
In September 2026, the National Reconstruction Fund Corporation invested **$10 million in equity** in HEO as part of a $37 million Series B round led by Beaten Zone Venture Partners. The NRFC was explicit about the strategic rationale: the investment will enable HEO to monitor 90 per cent of space objects of interest to Australian and allied defence and intelligence agencies, shoring up a critical sovereign defence capability.
HEO’s customer base already spans the Japanese Government, the Australian Department of Defence, and the U.S. National Reconnaissance Office, with a multi-year, seven-figure contract already secured. The company expects to grow its Australian workforce from 36 to 85 skilled roles by 2028. In a domain where the number of orbiting objects continues to climb, NEI is transitioning from a specialist service to a foundational layer of allied space domain awareness.
Launch and Return as Sovereign Infrastructure
Australia’s ability to place sensors in orbit—and bring payloads home—rests on a small number of launch and re-entry providers. Southern Launch, based in South Australia, closed a **$25 million Series A round in 2026** led by Brindabella and Company and the NRFC, with a $10 million NRFC allocation. The capital is scaling spaceport infrastructure, growing the workforce by 150 people, and expanding launch, re-entry, hypersonic testing, and range services.
Southern Launch’s trajectory is notable for its firsts. Since conducting Australia’s first commercial rocket launch in 2020, it facilitated what it describes as the world’s first commercial spacecraft re-entry at the Koonibba Test Range in February 2025, completing further re-entries including a May 2026 landing. Its customers include Varda Space Industries, Australia’s Defence Science and Technology Group, South Korea’s Perigee Aerospace, and the German Space Agency (DLR).
The NRFC framed the investment in explicitly sovereign terms: Southern Launch meets a critical need for launch and re-entry services in the Southern Hemisphere and addresses a global bottleneck by securing that capability for Australia. Re-entry capability is becoming strategically valuable as in-space manufacturing matures—returning materials and pharmaceuticals produced in microgravity requires a controlled, sovereign return pathway, not a dependence on foreign ranges.
Responsive Spacecraft for a Contested Domain
Space Machines Company approaches the same problem from the spacecraft side. Co-founded by Rajat Kulshrestha and George Freney, the company builds responsive, cost-effective spacecraft designed to safeguard satellite infrastructure. Traditional response systems can take months to deploy at significant cost, leaving assets exposed; Space Machines is redesigning that model around rapid production and advanced software.
The company won the Innovation in Aerospace award at the 2026 Endeavour Awards and holds a contract with the Advanced Strategic Capabilities Accelerator to develop the Space Threat Analysis and Response System—an AI-driven platform that detects threats to Australian and allied satellites and generates autonomous response options. Manufacturing is underway at its UTS Tech Lab facility in Botany, with ambitions to scale from tens to hundreds of spacecraft annually by the end of the decade.
Kulshrestha’s framing is direct: “Space is contested. That is not a hypothetical: it is today’s reality. Australia needs a homegrown capability to detect threats and respond to them. We are building it.”
The Industrial Base Behind the Capability
The space stack emerging in Australia is not a single company story. It is an ecosystem: HEO’s sensors, Southern Launch’s ranges, Space Machines’ responsive platforms, and enabling instrumentation from firms like Liquid Instruments, whose software-defined test equipment supported the Artemis II optical communications demonstration in 2026. The common thread is sovereign control over the sensing, launch, and response layers—capabilities that cannot be surge-purchased in a crisis.
