AUSTRALIA DATA CENTER COLOCATION MARKET SIZE

Australia data center colocation market size in terms of revenue, was valued at USD 2.24 billion in 2025 and is anticipated to reach USD 5.60 billion by 2031, growing at a CAGR of 16.49% during the forecast period. Australia is establishing itself as one of the most prominent locations for the development of colocation data centers in APAC, accounting for approximately 145 operational data centers spread across multiple locations like Sydney, Melbourne, Perth, Brisbane, Canberra, and others. Sydney and Melbourne are among the most attractive destinations for the development of colocation data centers in Australia.

Sydney alone consists of around 40 colocation facilities, and Melbourne hosts more than 24 colocation data centers in Australia. These cities have also attracted significant investments for data center development from several data center operators in 2025. Companies such as GreenSquareDC, NEXTDC, CDC Data Centres, AirTrunk and others invested in developing data centers across Sydney in 2025.

In Australia, colocation operators are increasingly partnering with investment companies, financial institutions, real estate firms, and property developers to source funds to develop large-scale data centers to address the rising demand for colocation services across the nation. The partnerships, joint ventures, collaborations, and Memorandum of Understandings (MoUs) are rising significantly among the data center operators in the country to support data center infrastructure expansion.

The Artificial Intelligence (AI)-optimized data centers consume vast amounts of electricity to process complex workloads, and several nations across the APAC region are witnessing significant power scarcity challenges. To meet the power requirements of Artificial Intelligence-ready data centers in Australia, the government is supporting utility companies and electricity suppliers through various initiatives to help them produce sufficient electricity. Additionally, the companies are focusing on developing multiple energy projects to supply large amounts of electricity to power AI data centers across Australia.

Growing cloud adoption among enterprises across various sectors, including finance, education, government, and other sectors, is leading companies to migrate their non-critical digital workloads to cloud platforms; the rising cloud migration among businesses and enterprises is anticipated to accelerate the demand for wholesale colocation services across Australia over the forecast period as cloud companies require large-scale, wholesale colocation space to store the data from multiple users.
