Australia has stepped onto the global stage at World Expo 2025 in Osaka, highlighting its strengths in innovation, advanced manufacturing, and sustainable resource development. With the theme “designing future society for our lives,” the expo, running until October 13, is expected to draw over 28 million visitors from around the world. For Australia, this is more than a display of technology—it is a chance to shape international conversations about sustainable growth, green industries, and the future of science.
A Platform for Future-Made Industries
At the heart of Australia’s participation is the message of building a “Future Made in Australia.” The Department of Industry, Science and Resources is using the pavilion to spotlight several fast-growing sectors. Chief among them are batteries and green metals manufacturing—industries crucial to reducing global dependence on fossil fuels. These industries are positioned not only to help Australia decarbonize but also to capture significant export opportunities in Asia, where demand for clean technologies is accelerating.
Australia is also showcasing its capacity to deliver on the critical minerals that underpin renewable energy technologies. Rare earths, lithium, and cobalt are central to the production of electric vehicles, solar panels, and wind turbines. By developing sustainable supply chains and transparent mining practices, Australia aims to position itself as a trusted partner in the global energy transition.
Carbon Capture and Sustainable Futures
Beyond renewable energy, the pavilion highlights efforts to make heavy industries more sustainable through carbon capture and storage (CCS). While still a developing technology, CCS has the potential to lower emissions in sectors where alternatives are not yet viable, such as cement, steel, and chemicals. Australian research institutions and companies are actively exploring commercial-scale applications, and the expo provides an international stage to demonstrate progress.
This focus on both green energy and carbon mitigation reflects Australia’s broader strategy: not only building future industries but also transforming existing ones. In doing so, the nation positions itself as an innovator rather than a follower in the global climate economy.
Science on Show: CSIRO and ANSTO
Australia’s national science agency, CSIRO, is at the center of the pavilion’s program. Visitors can learn about its work in biosecurity—an area of increasing global concern given the rising threats of pandemics and invasive pests. With global trade expanding, the ability to safeguard crops, livestock, and ecosystems has never been more critical. CSIRO’s biosecurity innovations, from genetic tracking of pathogens to digital surveillance tools, are designed to help protect both Australia and its trading partners.
Hydrogen is another focus. CSIRO is presenting its research on hydrogen as a clean fuel, particularly its potential in power generation, heavy transport, and industrial processes. Hydrogen exports, supported by Australia’s abundant renewable energy capacity, could be worth tens of billions of dollars in the coming decades.
The Australian Nuclear Science and Technology Organisation (ANSTO) is bringing science to life at the expo. Its live shows explore nuclear applications beyond energy, from food safety to medical imaging. By demonstrating how nuclear technologies support everyday health and safety, ANSTO aims to broaden public understanding of a field that often attracts controversy but offers tangible benefits.
Celebrating Partnerships with Japan
The expo is not just about showcasing technology; it is also a celebration of international partnerships. Earlier this year, Australia marked the 45th anniversary of its science and technology treaty with Japan. This longstanding collaboration has fostered joint research in renewable energy, advanced manufacturing, and space exploration.
In May, the pavilion welcomed special guests, including Australian astronaut Katherine Bennell-Pegg and Chief Scientist Professor Tony Haymet. Their presence underscored the role of human capital—scientists, engineers, and innovators—in shaping global progress. Bennell-Pegg’s story as an astronaut resonated with visitors, offering a human link to the possibilities of science and exploration.
Economic Opportunities Behind the Showcase
World Expos are as much about business as they are about culture. For Australian firms, the Osaka Expo represents a chance to attract investment, build partnerships, and expand market reach. The push for decarbonization is creating demand for technologies and resources that Australia can supply.
For example, the International Energy Agency estimates that global demand for critical minerals will quadruple by 2040 under net zero scenarios. With abundant reserves, Australia is well-positioned to supply much of this demand if it can scale extraction responsibly. Similarly, the global battery market is projected to grow to more than $400 billion by 2035, with Asia accounting for the majority of demand. Australia’s pavilion makes the case that it can play a role not just as a supplier of raw materials but as a manufacturer of higher-value products.
Aligning Innovation with Sustainability
Australia’s participation at Osaka highlights the delicate balance between resource development and environmental responsibility. The country has faced criticism for its reliance on coal and gas exports, yet its pavilion emphasizes a pivot toward sustainability. By focusing on green metals, clean hydrogen, and carbon capture, Australia signals to global partners that it is serious about aligning economic growth with climate goals.
However, experts note that delivering on these ambitions requires more than presentations at an expo. It demands coordinated policies at home, substantial investment in research and infrastructure, and strong regulatory frameworks to ensure that growth in new industries does not replicate the environmental issues of old ones.
Lessons for the Future
For visitors, the Australian pavilion provides an interactive glimpse into how a resource-rich nation can transition to a clean-energy powerhouse. For policymakers, it raises deeper questions: how quickly can industries scale, how much support should governments provide, and what trade-offs are acceptable in the pursuit of sustainability?
The Osaka World Expo 2025 is more than a global fair. It is a testing ground for the ideas, technologies, and partnerships that will shape the coming decades. Australia’s presence, rooted in science, innovation, and resources, positions it as both a contributor and a beneficiary in the drive toward a sustainable global economy.
Looking Ahead
As the expo continues, Australia’s task will be to turn global interest into lasting outcomes. That means attracting investors to green industries, building trust as a critical minerals supplier, and deepening collaborations with countries like Japan. It also means proving at home that its promises of sustainability can be matched by practice.
World Expos are remembered for the innovations they showcase and the visions they inspire. By highlighting batteries, hydrogen, biosecurity, and carbon capture, Australia has placed itself squarely in the conversation about how humanity can design a sustainable future. The challenge now lies in delivering on that vision, both for Australians and for the world.
