Australian National University scientists have developed world-first satellite technology to monitor eucalypt forest flammability from space, but the $15 million project sits in what researchers call the "technology Valley of Death" — proven in the lab yet unable to secure funding for the orbital testing needed to attract commercial investment.
The OzFuel project uses infrared sensors to detect chemicals that determine how quickly eucalypts burn. It's ready for a pathfinder mission within 18 months, yet funding pathways remain unclear even as Australia spends $448.7 million over 11 years to access American satellite data instead of building domestic capability.
The Technology
Marta Yebra, director of the ANU Bushfire Research Centre of Excellence and leader of the OzFuel project, explained that eucalypt flammability depends on multiple factors. "There is no single variable that determines how flammable a eucalypt is," she said. "One of the properties is moisture content, but there are other chemical components like oil content, cellulose and lignin. These all make the leaves more flammable."
ANU researchers analyzed thousands of eucalypt leaf samples to identify which infrared wavelengths detect key chemical compounds and flammability traits. Initial experiments with CSIRO tested how these traits influence fire behavior. At the Mount Stromlo research facility in Canberra, instruments normally used by astronomers to observe distant planets have been adapted for Earth observation from space.
Rob Sharp, director of ANU's Advanced Instrumentation Technology Centre, confirmed the concept works. "We've demonstrated that we can make the concept work in the laboratory," he said. "We're now at the stage from a technical perspective where we're looking to test it for viability on a spacecraft, and then attach it to a small satellite and get the prototype up in orbit."
The Funding Valley
Anna Moore, ANU Institute for Space director, estimated the OzFuel pathfinder mission would cost around $15 million. She warned that the lack of established funding pathways puts projects like OzFuel at risk. "You want that funding pipeline to be seamless," Moore said. "When a project like this is on hold, you not only lose key staff who hold the intellectual property that makes this a reality in the first place, you also lose momentum. And then lastly, we're talking here about bushfires. And the more we wait, the more bushfires we're going to have."
The funding gap comes despite government recognition of the problem. The royal commission following the 2019-20 Black Summer bushfires highlighted Australia's dependence on foreign-owned satellite data during natural disasters. In March 2022, the government announced a $1.16 million plan to build four Earth-observation satellites as part of the National Space Mission for Earth Observation. That program was axed as part of budget cuts a year later.
Foreign Dependence vs. Domestic Capability
Stuart Phinn, from the University of Queensland's School of the Environment, called Earth observation data "a critical piece of Australia's national security infrastructure for disaster preparedness and response." He said it had never been a better time to build Australia's national satellite capability. "If we don't act on this now, we're gradually going to lose that capability, and we're going to have to spend a lot more money buying in data and having potentially unreliable data and data that's not fit for Australian environments or Australian applications," Phinn said.
In July this year, the government released its Statement on Space, listing trusted space services including Earth observation as a key priority area. The statement noted the increasing role of these services in supporting public safety and security during emergencies.
The Department of Industry, Science and Resources said the government was working to secure access to critical satellite data by investing in strategic partnerships with the United States, the European Union and Japan. This included a $448.7 million investment over 11 years to ensure access to data from the United States Landsat Next satellite mission. The department didn't comment on whether there was any plan to build Australia's national satellite Earth observation capability.
Yebra pointed to the economic case for prevention. "There are lots of studies that broadly [indicate] that in natural disasters, $1 invested in prevention results in $10 of benefits in the damage that is avoided," she said. "Over the next 30 years, we could save more than $8.5 billion if we have more investment in technologies that can provide information that is useful to plan rather than react to bushfires."
Why This Matters:
Australia faces a choice between building domestic satellite capability or remaining dependent on foreign data providers for critical national security infrastructure. The government has committed nearly half a billion dollars to access American satellite data while Australian-developed technology sits unfunded despite a 10-to-1 return on prevention investment. As El Niño conditions threaten another severe bushfire season and natural disaster costs escalate, the funding gap between laboratory validation and commercial viability threatens to drain intellectual capital and delay deployment of Australian-specific solutions. The royal commission identified foreign satellite dependence as a vulnerability, yet three years after the government canceled its domestic Earth observation program, no clear pathway exists to translate proven Australian innovation into operational capability that could save billions in disaster costs.
