Segment Analysis

By Data Center Type: Self-build Dominance Yields to Colocation Acceleration

The Australia hyperscale data center market size for self-build campuses stood at USD 3.1 billion in 2025, translating to 59% share amid hyperscalers’ quest for bespoke designs that optimize AI throughput. Amazon’s multi-site AU USD 20 billion program underpins this dominance, delivering integrated availability zones connected via proprietary dark-fiber backbones. Yet the asset-light imperative is fuelling a 21.96% CAGR for hyperscaler colocation, as providers such as NEXTDC and AirTrunk offer shell capacity that can be fitted out in under 16 weeks. This flexibility is invaluable when AI demand spikes unpredictably or where land scarcity in Sydney’s North Shore elongates permitting timelines. Over the forecast horizon, self-build share is expected to decline gradually as operators blend owned and leased footprints, ensuring the Australia hyperscale data center market remains responsive to shifting workload geographies.

Colocation growth benefits from scale economics: a single AirTrunk phase can allocate 32 MW of contiguous white space at a lower marginal cost per kilowatt than greenfield self-builds. Additionally, strategic partnerships—such as Google’s Australia Connect alliance with NEXTDC—embed carve-outs for submarine-cable landing gear inside colocation grounds, accelerating international service launches. As sovereign-cloud regulations tighten, colocation operators able to guarantee citizenship-cleared staff will deepen their value proposition to public-sector customers, further rebalancing demand within the Australia hyperscale data center market.

By Component: IT Infrastructure Leadership Challenged by Cooling Innovation

IT infrastructure represented 45% of 2025 spend, driven by exponential GPU adoption for large-language-model training clusters. The Australia hyperscale data center market size for servers alone reached USD 1.2 billion as operators migrated from dual-socket x86 blades to PCIe-Gen5 GPU assemblies with non-volatile memory express (NVMe) fabrics. Storage arrays scale similarly, with hyperscalers gravitating toward all-flash NVMe over Fabric to meet AI dataset throughput. Networking leapfrogs to 800 Gbps Ethernet to prevent bottlenecks during distributed training epochs, illustrating that compute and interconnect upgrades move in lockstep across the Australia hyperscale data center market.

Liquid-cooling systems, however, post the fastest expansion at 22.54% CAGR. SMC’s HyperCube immersion tanks and Digital Realty’s liquid-to-chip manifolds enable rack densities north of 80 kW while lowering fan energy draw by 25%.
