Australia Cloud Services Market Size, Share and Forecast Trends - Growth Analysis and Outlook Report (2026-2035)

How large is the Australia cloud services market, and where is it heading?

Quick Answer

The Australia cloud services market covers the delivery of computing infrastructure, software platforms, and application services over the internet, spanning Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Desktop as a Service (DaaS) across public, private, and hybrid deployment models. Gartner puts Australian public cloud end-user spending at AUD 26.6 billion in 2025, up 18.9 per cent from AUD 22.4 billion in 2024. SaaS is the largest segment at ~AUD 13 billion, followed by PaaS at AUD 8.0 billion and IaaS at AUD 5.6 billion, with IaaS growing the fastest at 24.2 per cent as AI workloads pull compute into cloud infrastructure. The cloud services market is projected to reach AUD 98.50 billion by 2035 at a 14.0 per cent CAGR, anchored by AUKUS-era hyperscaler buildout, a government sector still early in cloud migration, and continued enterprise AI adoption.

Market Overview

Australia's cloud services market has crossed a threshold. Year-on-year growth near 19 per cent is rare for a market of this scale, and for context: the cloud services market was worth around AUD 12.2 billion as recently as 2022, per an IDC whitepaper commissioned by Microsoft. It has more than doubled in three years, and isn't slowing down. Gartner surveyed 3,186 CIOs globally in 2025, including 109 from ANZ, and found 83 per cent of ANZ CIOs rank cloud platforms among their top technology investments, sitting just behind cybersecurity and data analytics.

Three forces are pushing the Australia cloud services market higher from here. First, the hyperscalers are placing their biggest bets on Australian infrastructure yet: AWS has committed AUD 20 billion in data centre investment between 2025 and 2029, and Microsoft has pledged AUD 5 billion to expand from 20 to 29 data centres across Sydney, Melbourne, and Canberra. That's AUD 25 billion of committed capital flowing into the physical backbone of the cloud services market. Second, the federal government is finally moving seriously on cloud adoption; only about 10 per cent of government IT spending currently goes to public cloud, which means there's an enormous runway for public sector migration. Third, AI is changing what cloud infrastructure is actually used for, making IaaS the fastest-growing segment as organisations race to provision compute capacity for AI workloads at scale.

Key Market Trends and Insights

• SaaS leads by spending volume, IaaS is growing fastest: SaaS reached close to AUD 13 billion in 2025, growing 15.5 per cent. IaaS grew 24.2 per cent to AUD 5.6 billion. PaaS came in at AUD 8.0 billion, up 21.1 per cent. Every segment is in double-digit growth territory, which is rare for a market of this scale.
• The federal government is still an early-stage cloud adopter: Only 10 per cent of government IT spending sits on public cloud, per Mandala Partners. Replacing legacy systems with cloud and AI-enabled platforms could unlock AUD 1.4 billion in annual productivity gains. The DTA Cloud Policy, taking effect July 2026, mandates transparent cloud expenditure management across all Commonwealth agencies.
• Data centre capacity is on track to more than double by 2030: Deployable capacity is projected to grow from 1,350 MW in 2024 to 3,100 MW by 2030, per Mandala (commissioned by AEMO via Westpac IQ). Australia ranked second globally for data centre investment in 2024, attracting AUD 6.7 billion.
• National security is now a commercial cloud driver: The AUD 2 billion, 10-year Top Secret Cloud deal with AWS, announced July 2024, put cloud at the centre of Australia's national security infrastructure. When the government moves its most classified data to cloud, it changes the conversation for every government buyer still weighing migration.
• AI is the growth accelerant that wasn't priced into earlier forecasts: Generative AI is pulling more compute demand into IaaS. Microsoft's 2024 Copilot trial in the Australian Public Service found participants saved roughly one hour per day, exactly the kind of productivity data that turns into cloud budget authorisations.

Australia Cloud Services Market Size and Forecast

Key Takeaways: Australia Cloud Services Market

A Cloud Services Market That Has Doubled in Three Years

AUD 26.6 billion in 2025. AUD 12.2 billion in 2022. Doubling in three years reflects a structural shift in how Australian organisations, from banks and supermarkets to federal agencies and hospitals, provision and pay for technology infrastructure. The move from capital expenditure on physical servers to operational expenditure on cloud services was always going to happen; it just happened faster than most projected. Every segment is in double-digit growth. The 14 per cent CAGR applied for 2026 to 2035 is deliberately conservative relative to the 18-19 per cent rates of 2024 and 2025; at 14 per cent, the arithmetic still gets to AUD 98.50 billion by 2035.

AWS and Microsoft Have Committed AUD 25 Billion to Australian Infrastructure

AUD 20 billion from AWS between 2025 and 2029. AUD 5 billion from Microsoft starting October 2023. That's AUD 25 billion from the two largest hyperscalers going into Australian data centre infrastructure, and it doesn't include Google Cloud, Oracle, or domestic operators like NEXTDC and Macquarie Technology Group. This isn't speculative capital: AWS has had a Sydney region operational since 2012 and Melbourne since 2023. Microsoft has data centres across all three major cities. The AUD 25 billion is additive expansion on top of infrastructure already carrying significant commercial load.

The Government Sector Is the Biggest Untapped Opportunity in the Cloud Services Market

Only about 10 per cent of Australian Government IT spending sits on public cloud. That figure, from Mandala Partners analysis prepared for the Tech Council of Australia, is probably the most consequential number in the Australia cloud services market right now. Mandala calculated replacing legacy government IT with cloud and AI-enabled platforms could generate AUD 1.4 billion per year in productivity gains over the next decade, alongside more than AUD 10 billion in infrastructure cost savings. Agencies could reduce IT budgets by up to 28 per cent. The DTA Cloud Policy effective July 2026 is the clearest signal that the government intends to move at scale.

Key Insight

The Australia cloud services market sits at an inflection point. Consumer and enterprise adoption is mature and growing fast. Government adoption is far behind at about 10 per cent. The hyperscalers are building for a market they expect to be several times larger than today. And AI is pulling more compute demand into cloud infrastructure than any near-term forecast fully captures. The 14 per cent CAGR used here is almost certainly conservative.

Key Trends and Recent Developments in the Australia Cloud Services Market

A few things are happening in the cloud services market simultaneously, and they're reinforcing each other. Infrastructure investment is creating capacity. Government policy is creating mandate. AI adoption is creating demand. And landmark deals are drawing institutional capital to Australian cloud infrastructure in a way that will keep investment flowing for years.

AWS Commits AUD 20 Billion to Australian Data Centres, June 2025

On 14 June 2025, Prime Minister Anthony Albanese stood alongside AWS CEO Matt Garman in Seattle to announce AUD 20 billion in Australian data centre investment between 2025 and 2029: the largest technology infrastructure commitment ever announced by an international company in Australia. This built on AWS's April 2023 pledge of AUD 13.2 billion, which included launching the Melbourne Region and Perth Local Zones. The June 2025 announcement added nearly AUD 7 billion, covering expanded data centres in Sydney and Melbourne plus three new solar farms in Victoria and Queensland. AWS has been in Australia since 2012 and became the cloud provider of choice for major banks, telcos, and the AUD 2 billion Top Secret Cloud.

Microsoft's AUD 5 Billion Buildout and February 2026 Whole-of-Government Arrangement

Microsoft's AUD 5 billion commitment from October 2023 was the most publicly prominent cloud investment announcement in Australian technology history at the time. Expanding from 20 to 29 data centre sites, partnering with TAFE NSW on a Data Centre Academy, and launching the Microsoft-ASD Cyber Shield covered infrastructure, skills, and national security simultaneously. The February 2026 five-year Volume Sourcing Arrangement with the DTA created a streamlined procurement path for Commonwealth agencies to access Azure, Microsoft 365, and Copilot under a pre-negotiated contract, deepening existing relationships rather than creating new ones.

The Blackstone AUD 24 Billion AirTrunk Acquisition Reset Data Centre Valuations

Blackstone and Canada Pension Plan Investment Board closed the acquisition of AirTrunk in December 2024 at an implied enterprise value of over AUD 24 billion: the largest data centre transaction globally, the largest Australian M&A deal of 2024, and Blackstone's largest Asia Pacific investment. AirTrunk was founded by Robin Khuda in 2015 and opened Australia's first hyperscale data centre in Sydney in 2017. Macquarie Asset Management took a majority stake in 2020 at ~AUD 3 billion; four years later Blackstone paid AUD 24 billion, roughly an eight-fold increase. At acquisition, AirTrunk had 800+ MW committed across 11 sites in Australia, Japan, Malaysia, Hong Kong, and Singapore, with land for more than 1 GW of future growth.

Australia Cloud Services Market Segmentation

Market Breakup by Service Type

• Software as a Service (SaaS): The largest segment at ~AUD 13 billion in 2025, growing 15.5 per cent. It's the most mature cloud category with the highest switching costs and most predictable renewals. Enterprise SaaS in Australia covers Microsoft 365 (effectively ubiquitous), Salesforce, ServiceNow, Workday, and a long tail of industry-specific apps. Generative AI integration, particularly Microsoft Copilot, is driving continued growth.
• Platform as a Service (PaaS): AUD 8.0 billion in 2025, up 21.1 per cent from AUD 6.6 billion. Platform services cover cloud-native development tools, databases, API management, and increasingly AI and machine learning training and deployment. Gartner's combined CIPS offerings (infrastructure plus platform) are projected to account for 72 per cent of IT spending on IaaS and PaaS by 2025, up from 70 per cent in 2022.
• Infrastructure as a Service (IaaS): AUD 5.6 billion in 2025, the fastest-growing segment at 24.2 per cent. The reason is AI. Training large language models, running inference at scale, and supporting AI analytics pipelines require GPU-enabled compute that organisations are buying through hyperscaler IaaS rather than building on-premise. AWS, Azure, and Google Cloud are all investing in GPU clusters in their Australian regions.
• Desktop as a Service (DaaS): Smaller but growing segment driven by hybrid work adoption, zero-trust security requirements, and the shift away from physical endpoint management. Particularly relevant to the Australian Government's sovereign cloud requirements.

Market Breakup by Region

• New South Wales: The dominant region by data centre capacity and enterprise cloud services market spending. Home to AWS, Azure, and Google Cloud Sydney regions; AirTrunk SYD1 (130+ MW); the Macquarie Park campus.
• Victoria: AWS Melbourne Region from 2023; major NEXTDC and AirTrunk capacity; NEXTDC M4 with AUD 2 billion commitment. Second-largest enterprise cloud services market.
• Australian Capital Territory: Federal government sovereign cloud demand drives ACT. Macquarie Data Centres serves 42 per cent of federal agencies; Microsoft Canberra sites support classified workloads.
• Queensland: AWS solar farms, the Quinbrook AUD 2.5 billion Supernode renewables-powered data centre project, and growing SME cloud adoption.
• Western Australia: First AWS Local Zones in Australia (Perth); energy, mining and resources sector cloud; Asia Pacific export proximity.

Competitive Landscape and Key Players in the Australia Cloud Services Market

The Australia cloud services market is a hyperscaler oligopoly at the infrastructure layer. AWS, Microsoft Azure, and Google Cloud own the vast majority of IaaS and PaaS spending. SaaS is more fragmented, but Microsoft dominates through Microsoft 365's near-universal adoption in enterprise and government. Domestic players compete primarily in the data centre, managed cloud, and sovereign cloud segments, and some of them are very large.

Amazon Web Services

The market's dominant infrastructure provider, with the deepest government relationships of any hyperscaler in Australia. Operating here since 2012; over 140 Commonwealth, state, and territory agencies use its services for transport, health, education, and tax. The July 2024 ASD Top Secret Cloud deal locked in the most sensitive government workloads for a decade, and the June 2025 AUD 20 billion infrastructure commitment signals a long-term view on Australian cloud services market growth.

Microsoft Azure

Microsoft's AUD 5 billion commitment from October 2023 was the most publicly prominent cloud investment in Australian technology history. Expanding from 20 to 29 data centre sites, partnering with TAFE NSW, and launching the Microsoft-ASD Cyber Shield covered infrastructure, skills, and national security. The February 2026 DTA Volume Sourcing Arrangement streamlines Commonwealth procurement.

Google Cloud

Operates a Sydney region and has a growing presence across enterprise verticals and education. Vertex AI and Gemini are increasingly relevant as Australian organisations move from infrastructure procurement to AI workload deployment. Google hasn't made a single infrastructure announcement comparable to AWS or Microsoft, but has been building its customer base steadily.

NEXTDC

Australia's largest listed independent data centre operator, with 17 facilities across Sydney, Melbourne, Brisbane, Perth, and Canberra, plus Asia and NZ expansion. By late November 2025, contracted utilisation grew 29 per cent to 316 MW, with a forward order book up 53 per cent to 205 MW. A new OpenAI contract sits at the headline of that order book. NEXTDC lifted FY 2025-2026 capital spending guidance by AUD 400 million and committed AUD 2 billion to its M4 Melbourne facility.

AirTrunk (Blackstone)

Now owned by Blackstone and CPP Investments following the AUD 24 billion acquisition closing in December 2024, AirTrunk is the largest hyperscale data centre operator in Asia Pacific. The SYD1 campus in Sydney holds 130+ MW. Across 11 sites in Australia, Japan, Malaysia, Hong Kong, and Singapore, the company has 800+ MW of committed capacity and land for 1+ GW of future growth.

Macquarie Technology Group

Operates sovereign Australian data centres through Macquarie Data Centres, serving 42 per cent of the Australian Government, three of the four hyperscalers, and major financial services customers from Sydney and Canberra campuses. 200+ NV1 security-cleared engineers and Australian Government certification for sensitive workloads. The IC3 SuperWest facility in Macquarie Park targets Phase 1 completion in September 2026 following AUD 350 million investment.

Other key players include Salesforce, Oracle Cloud, IBM Cloud, SAP, ServiceNow, Broadcom (VMware), Adobe, Datacom, Fujitsu Australia, Telstra Enterprise, and DXC Technology.
