An Australian company sits at the centre of one of Southeast Asia’s next big artificial intelligence build-outs. Firmus, the Aussie AI infrastructure startup best known for its energy-efficient “Sustainable Metal Cloud” platform, is teaming with Singapore-based data centre operator DayOne and US chip giant Nvidia to develop a new AI data centre in Indonesia, according to reporting by The Business Times.
The context
Southeast Asia has become one of the hottest battlegrounds for AI infrastructure. As demand for the specialised graphics processing units (GPUs) that train and run large language models has outstripped supply, a wave of operators has raced to stand up “AI factories” close to the region’s booming digital economies. Indonesia, with a population north of 270 million and a rapidly digitising services sector, has emerged as a prime target for that capacity.
Firmus is an unusual entrant in that race. The company grew out of Australian efforts to build greener computing, pairing Nvidia hardware with immersion-cooling technology that submerges servers in a special fluid to strip out heat. That approach, marketed under the Sustainable Metal Cloud banner, is pitched as a way to cut the enormous energy and water footprint of AI compute, a pitch that resonates as regulators and communities grow wary of the resources these facilities consume.
DayOne, meanwhile, is a heavyweight in the regional market. Spun out of Chinese operator GDS Holdings to house its international business, the Singapore-headquartered firm has been aggressively expanding hyperscale capacity across Johor in Malaysia, Batam in Indonesia and other hubs positioned to serve Singapore’s constrained grid. A tie-up with Firmus and Nvidia slots neatly into that strategy.
The news
Under the arrangement reported by The Business Times, the three parties will collaborate on an Indonesian data centre built around Nvidia’s AI computing platform, with Firmus supplying its efficiency-focused deployment model and DayOne contributing the site, power and operational muscle. The project extends a working relationship the companies have cultivated across the region, where earlier Firmus deployments have leaned on partners to secure land and electricity while Firmus handles the specialised compute stack.
For Nvidia, the deal is another node in a sprawling network of regional partnerships designed to seed its chips into every major market. The company has spent the past two years signing agreements with governments and operators from the Gulf to Southeast Asia, framing the effort as building “sovereign AI” capacity so nations can train models on local data rather than shipping it offshore. An Indonesian facility fits that narrative squarely.
The exact scale, location and timeline of the Indonesian build were not fully detailed in the initial reporting, and the companies have released limited public specifics. What is clear is that the project marks a further step in Firmus’s transformation from a niche Australian sustainability play into a cross-border supplier of AI infrastructure in one of the world’s fastest-growing compute markets.
Two ways to read it
Optimists see the deal as validation that Australian deep-tech can compete at the frontier of a capital-intensive, globally contested industry. Firmus’s cooling technology has attracted attention precisely because the AI boom is running headlong into physical limits, grids that cannot deliver enough power, and cooling systems that guzzle water. If Firmus can demonstrate that its approach works at hyperscale in a hot, humid climate like Indonesia’s, it strengthens a genuinely exportable Australian intellectual property story.
Sceptics counter that the heavy lifting, the land, the grid connections, the balance-sheet firepower, increasingly sits with regional giants like DayOne and with Nvidia, whose chips are the scarce input everyone is chasing. In that reading, an Australian startup risks becoming a technology supplier and brand partner in projects whose economics and control reside elsewhere. There are also familiar concerns about the sustainability claims themselves: even the most efficient AI data centre still consumes vast amounts of energy, and “green” branding can outrun the reality of facilities plugged into fossil-heavy grids.
What it means for Australia
For the local ecosystem, the story cuts two ways. On one hand, it is a rare example of an Australian company exporting AI infrastructure know-how into Asia rather than importing it, the kind of outcome policymakers say they want when they talk about turning research strength into industry. Firmus’s international momentum could help attract talent and capital back home, and it gives Australian investors a home-grown name to point to in a sector otherwise dominated by American and Chinese players.
On the other hand, the deal underlines an uncomfortable question: why is the marquee build happening in Indonesia rather than Australia? Domestic data centre demand is surging, with major operators and hyperscalers expanding across Sydney, Melbourne and increasingly regional sites. But Australia’s own grid constraints, planning delays and the sheer competition for power have pushed some of the most ambitious AI capacity offshore, closer to cheaper land and, in some cases, more accommodating energy settings. If a company built on Australian sustainability engineering is deploying its flagship efficiency tech abroad, it raises the stakes for whether Australia can capture the industrial upside of the AI boom at home, or merely originate the ideas that others scale.
There is also a strategic dimension. Canberra has been sharpening its focus on critical technology and regional digital ties, and Australian involvement in Indonesian AI infrastructure sits at the intersection of both. Deeper commercial links with Jakarta’s digital economy could complement the broader push to embed Australia in Southeast Asia’s technology supply chains, a priority repeatedly flagged in trade and foreign-policy circles.
What’s next
Attention now turns to the specifics the companies have yet to spell out: how large the Indonesian facility will be, where it will draw its power, and when GPUs will actually come online. Expect the sustainability claims to face scrutiny, particularly around energy sourcing and water use in a tropical climate. Watch, too, for whether the partnership becomes a template, a repeatable model that Firmus and DayOne roll out across other Southeast Asian markets, with Nvidia silicon at the core.
For Firmus, the immediate test is execution at scale far from home. For Australia, the deal is a prompt to ask whether it is content to be the birthplace of clever AI infrastructure ideas, or whether it intends to host them.
