Who controls AI is becoming the bigger questionKnowledge may be the next asset battleDecidr secures Australian AI infrastructure with SCX.ai  Special Report:  The AI conversation inside large organisations appears to be changing.Not long ago, much of the focus was around capability. Could AI write content, automate workflows, analyse information or improve productivity?Today, another question is increasingly becoming part of the discussion: where does the AI actually run, who controls the infrastructure behind it and where does all that knowledge end up living?That shift sits behind Decidr AI Industries' (ASX:DAI) latest move, with the company signing a strategic commercial partnership with SouthernCrossAI (SCX.ai), an Australian sovereign AI cloud provider.The agreement names SCX.ai as Decidr's first sovereign inference partner in Australia and forms part of the company's broader Knowledge Security roadmap and the rollout of DecidrOS to Australian enterprise customers.The partnership effectively gives Decidr an Australian-based infrastructure layer where enterprise customers can run AI workloads and keep their data within Australian jurisdiction.It also becomes the first Australian node within Decidr's broader multi-jurisdiction sovereign inference architecture.In practical terms, Decidr is building a network of AI infrastructure across different regions to give customers greater control over where their AI systems and data operate, alongside its wider strategy across Europe, Asia-Pacific and the US.Decidr CTO Michael Cindric says, “Our partnership with SCX furthers our commitment to offering a true sovereign data solution for organisations rapidly navigating AI. This is an integral part of our strategy for avoiding the great knowledge heist of our time.”Why sovereignty is becoming part of the AI discussionWhile some of the terminology can sound highly technical, the idea itself is relatively straightforward.AI systems need computing infrastructure — essentially the servers and computing power sitting behind the scenes — to perform work.In AI terminology, this process is known as "inference", which is the point where an AI model takes information, processes it and produces an output or decision.The company says the question enterprise buyers are now asking is not only whether AI can do the task but who owns the infrastructure the task runs on, and who controls the AI model itself.That concern is becoming increasingly relevant as data residency requirements continue expanding across industries, including financial services, healthcare and government.Decidr noted that Australia's National AI Plan 2025, together with obligations around where information can be stored, has shifted jurisdictional control from a procurement preference into a procurement requirement.There is also an international element driving that conversation.The company pointed to the United States CLOUD Act, which allows US law enforcement agencies to compel data access from US-controlled providers regardless of where that information is physically stored.For organisations dealing with sensitive information, where AI workloads run, and who ultimately controls that infrastructure, is increasingly becoming part of the decision making process.Building Australian node inside global architectureDecidr's response has been what it describes as a multi-jurisdiction sovereign inference architecture.Rather than relying on a single provider or geography, the company is building a curated set of infrastructure partners selected according to jurisdiction, and their ability to operate within a customer's own control environment.In other words, organisations can choose where their AI systems and data are run, rather than being locked into a single provider or location.SCX.ai now becomes Decidr's first Australian hub within that wider architecture.David Brudenell, executive chairman of DAI, said the partnership formed part of a broader strategy being built around global enterprise demand."The agentic economy runs on inference, and inference runs on infrastructure," Brudenell said."Partnering with SCX.ai gives Decidr customers a domestic, high-performance foundation on which to deploy their own fine-tuned models with confidence."It is the first Australian node in a broader multi-jurisdiction architecture we are building to meet enterprise demand for sovereign AI globally."How SCX.ai fits into the bigger pictureFounded and led by David Keane, SouthernCrossAI specialises in Australian-based AI infrastructure designed to keep AI models, data and system activity within Australian jurisdiction.The company launched what it described as Australia's first sovereign AI cloud through a partnership with SambaNova in late 2025 before bringing its first Australian sovereign AI processing hub online at Equinix's SY5 data centre in Sydney earlier this year.SCX.ai has also publicly outlined plans for another 10 nodes across Australia and the Asia-Pacific region.Decidr said the partnership included plans to expand into additional Australian and Asia-Pacific locations while also providing enterprise-scale infrastructure for agentic AI systems running on DecidrOS.Supporting Decidr's Knowledge Security roadmapThis partnership also fits directly into a broader strategy Decidr has been building around organisational knowledge and ownership.The company has previously discussed knowledge becoming one of the most valuable assets within modern businesses.Through its Sugarwork business and professional services channel partners, Decidr is commercialising what it calls its Knowledge Security offering.The objective is to capture how organisations make decisions, use that knowledge to fine-tune AI models and run those models on infrastructure controlled by the enterprise itself.The agreement with SCX.ai effectively delivers the Australian computing infrastructure supporting that strategy."Decidr is one of the most sophisticated buyers of sovereign inference in the Australian market,” said David Keane, chief executive of SCX.ai."Together with Decidr we will give Australian enterprises and government customers the ability to run agentic AI on infrastructure that is unambiguously inside Australian jurisdiction."Decidr said the partnership accelerated its Knowledge Security roadmap and strengthened its commercial activity in Australia. It also establishes the Australian foundation of its broader sovereign AI architecture.Now read more: Decidr chases AI’s ‘control layer’ opportunity with $15m cap raiseThis article was developed in collaboration with Decidr
