Australia is home to a rapidly growing number of data centres, driven by the increasing demand for digital services and cloud computing. As of recent years, there are over 200 data centres spread across the country, with the majority located in major cities like Sydney, Melbourne, and Brisbane. These facilities range from small enterprise data centres to large-scale hyperscale centres operated by global tech giants. The growth of data centres in Australia reflects the country's strategic importance in the Asia-Pacific region as a hub for digital infrastructure, supporting everything from local businesses to international cloud services.

The cost of building a data centre can vary widely depending on factors such as location, size, design specifications, and the level of technology incorporated. On average, constructing a small to mid-sized data centre can range from several million to tens of millions of dollars. Larger, hyperscale data centres, which are designed to support massive computing needs, can cost hundreds of millions to over a billion dollars. These costs include land acquisition, construction, electrical and cooling infrastructure, security systems, and the installation of servers and networking equipment. Additionally, ongoing operational costs such as energy, maintenance, and staffing must be factored into the total investment, making data centres a significant financial commitment for any organisation.
