Australia Data Centre Market Size, Share, Trends, Analysis, and Forecast 2026 to 2035

Quick Answer

The Australia data centre market covers the construction, operation, and leasing of hyperscale, colocation, and enterprise data centre facilities. Australia ranked second only to the United States as a data centre investment destination in 2024, attracting US$6.7 billion (Knight Frank, cited in CEFC/Baringa December 2025). Announced investments since 2023 have scaled to more than AUD 100 billion. Deployable capacity stood at ~1,350 MW in 2024 and is projected to more than double to 3,100+ MW by 2030, requiring ~AUD 26 billion in new investment. Under the CEFC/Baringa central case, operational capacity reaches 2.2-3.2 GW by 2035, representing 8-11 per cent of projected electricity consumption. The data centre market is projected to reach AUD 16.76 billion by 2035 at an 18.0 per cent CAGR.

Market Overview

The Australia data centre market is in the midst of a structural transformation with few parallels in the country's industrial history. The Clean Energy Finance Corporation's December 2025 report, produced by Baringa, describes Australia as the second-largest data centre investment destination globally in 2024 with US$6.7 billion in capital investment, trailing only the United States. As the third-largest data centre market in the Asia-Pacific region, representing ~10 per cent of the region's total capacity, Australia sits at the centre of a global race for AI infrastructure.

The investment signals are unambiguous. AWS committed AUD 20 billion to Australian data centre infrastructure between 2025 and 2029, described by both the company and the Prime Minister as the largest technology investment in Australian history. In December 2025, OpenAI signed a Memorandum of Understanding with NEXTDC to develop a AUD 7 billion hyperscale AI campus at NEXTDC's S7 site in Eastern Creek. In October 2025, Firmus announced AUD 4.5 billion in initial investment for Project Southgate, with potential scale to AUD 73.3 billion. The NSW Government separately backed 15 data centre projects worth AUD 51 billion. The Department of Industry, Science and Resources confirms total announced investments have scaled to 100-plus billion.

The Australian Government's analysis projects AI and automation alone could generate up to AUD 600 billion for GDP by 2030, and data centres are the physical infrastructure making this possible. AEMO projects electricity demand from data centres to triple by 2030, rising from ~4 TWh and 2 per cent of NEM grid supply in 2024 to ~9 per cent of total NEM and WEM consumption under the CEFC/Baringa central case by 2035. Without additional renewable energy investment, data centre load growth could increase wholesale electricity prices in NSW by up to 26 per cent and Victoria by 23 per cent by 2035.

Key Market Trends and Insights

• Australia second only to the US as a 2024 data centre investment destination: Knight Frank's 2025 Global Data Centre report (cited in CEFC/Baringa December 2025) confirms Australia attracted US$6.7 billion in data centre capital investment, second only to the United States globally. Sydney is ranked the eighth largest data centre market in the world by Cushman & Wakefield's 2025 Global Data Centre Market Comparison.
• Capacity set to more than double by 2030: Deployable data centre capacity stood at ~1,350 MW in 2024 and is projected to exceed 3,100 MW by 2030, requiring ~AUD 26 billion in new investment. Under the CEFC/Baringa central case, operational rated capacity reaches 2.2-3.2 GW by 2035, up from ~300 MW in FY 2024-2025.
• Hyperscalers and AI driving demand beyond self-build programmes: Cushman & Wakefield's H2 2025 APAC Update confirms Asia Pacific's total pipeline expanded by 2,751 MW in H2 2025 to reach 19,371 MW. Leasing demand from Western hyperscalers for colocation capacity continues to exceed their self-build programmes, particularly in Sydney.
• Data Centres Australia peak body launched November 2025: The industry's first dedicated peak body was launched on 28 November 2025. Founding members include AirTrunk, AWS, CDC Data Centres, Microsoft, NEXTDC, Equinix, Goodman Group, Schneider Electric, STACK, and TikTok.

Key Takeaways: Australia Data Centre Market

Australia Is the Asia-Pacific's Pre-eminent Sovereign AI Infrastructure Hub

The combination making Australia attractive for data centre investment is difficult to replicate elsewhere in the Asia-Pacific. Political stability and Five Eyes membership enable government-grade sovereign workloads. Abundant renewable energy potential, increasingly matched with firm capacity commitments, addresses the power sustainability challenge constraining growth in Singapore and other land-constrained markets. Australia's time zone, fibre connectivity, and proximity to Asian markets without being subject to Chinese or other authoritarian legal regimes makes it uniquely positioned for regional AI sovereignty. Announced plans exceed AUD 100 billion: Amazon's AUD 20 billion, Microsoft's AUD 5 billion, Blackstone's AUD 24 billion AirTrunk acquisition, and OpenAI's AUD 7 billion via NEXTDC.

The Energy Challenge Is the Defining Constraint on Market Growth

The CEFC/Baringa December 2025 report is the most comprehensive analysis to date of data centre energy implications. Without additional renewable energy investment matched to demand growth, data centres could increase NSW wholesale electricity prices by 26 per cent and Victoria by 23 per cent by 2035 under the central case. The good news: the CEFC/Baringa modelling finds this is manageable with the right policy settings. An additional 3.2 GW of renewables, alongside 1.9 GW of large-scale battery storage, would limit price rises to 7 per cent in NSW and 6 per cent in Victoria. Data Centres Australia's research confirms 70 per cent of current data centre energy is already offset through renewables or direct purchases.

Structural Evolution: From Colocation to Hyperscale Sovereign AI

The Australia data centre market is undergoing a structural shift driven by three simultaneous forces. First, the shift in rack density from 3 kW to 70+ kW requires entirely new facility designs, with liquid cooling becoming a prerequisite. Second, hyperscalers are moving from exclusively leasing colocation space to building owned facilities and anchor-tenanting purpose-built campuses, exemplified by the OpenAI-NEXTDC model at S7 Eastern Creek. Third, sovereign compute is emerging as a distinct product category under the National AI Plan. Cushman & Wakefield projects Sydney and Mumbai will both reach 1 GW operational capacity by 2028, with Australia becoming a 2 GW total data centre market by the same year.

Key Insight

The formation of Data Centres Australia in November 2025, backed by operators representing the majority of deployable data centre capacity, signals the sector's transition from individual operators lobbying separately to a coordinated industry voice. The founding membership includes both the largest domestic operators (NEXTDC, CDC) and the hyperscalers driving the global AI infrastructure wave (AWS, Microsoft), creating a rare alignment of domestic and foreign capital behind a single industry framework. The peak body's water commitment data and renewable energy offset figures provide, for the first time, a credible industry-sourced baseline.
