Data centres in Australia: your questions answered

Data centres in Australia have become a topic of much debate and speculation. Here are some of the most frequently asked questions and their answers, based on the information provided:

1. What data is stored in data centres, and who owns it?

Data centres store a vast array of data in various formats, similar to modern libraries. They hold archives and backups, and process requests to serve data to users. The largest data centres specialize in artificial intelligence (AI) workloads, using specialised hardware to perform complex calculations. Data ownership is typically determined by the individual, service provider, or the commercial contracts between data centre operators and tenants.

However, data sovereignty can be a contentious issue, as data may be subject to access by authorities in other jurisdictions.

2. Are data centres regulated? How?

Data centres are not currently regulated at a national level in Australia. While there are some local planning processes and guidelines, they are largely unenforceable and not legally binding. Each state and territory has its own varying requirements, with only Victoria, New South Wales, Tasmania, and South Australia having some form of policy or strategy in place. The federal government is working on developing consistent mandatory standards for energy, water, and land use, but these standards are yet to be drafted.

3. Do communities get a say in where data centres go?

Community input is not systematically considered in the planning process for data centres in Australia. While some states and territories have policies or strategies to regulate data centres, there is no consistent framework that ensures community engagement or consent. This lack of involvement has led to growing opposition to large-scale data centre development.

4. Why do data centres need to be located near where people live?

Data centres are often located near population centers to reduce latency and improve the speed at which data can be accessed by users. By positioning data centres closer to where people live, businesses can minimize the time it takes for data to travel between the user and the server, resulting in faster loading times and a better user experience. However, this proximity also raises concerns about the environmental impact and community concerns related to data centre development.

5. What’s in it for us? Why does the government want them?

The government's interest in data centres stems from the potential economic benefits they can bring to the country. Billed as a vital infrastructure investment, data centres attract significant investment and create jobs. However, the government has not yet provided a clear justification for their support, as there is currently no consistent national framework for regulating these facilities.

6. Where do the profits go?

The profits generated by data centres are typically reinvested in the business, allowing for the expansion and improvement of services. Some of the profits may also be distributed as dividends to shareholders, depending on the ownership structure of the data centre operator. As data centres become increasingly important in the AI-driven economy, their profits are likely to play a more significant role in shaping the economy.

7. Can the water be recycled?

Data centres can employ water recycling systems to minimize their water usage. These systems treat wastewater and reuse it for cooling and other purposes within the facility. However, the extent to which water recycling is implemented varies between data centres and depends on factors such as cost, technology, and availability of resources.

8. What happens to them when the AI bubble pops?

The term "AI bubble" is used to describe a potential overvaluation of AI-related investments, similar to the dot-com bubble of the late 1990s and early 2000s. When such a bubble bursts, it could lead to a decline in investments in AI and related technologies. As a result, the demand for data centre capacity may decrease, potentially affecting the long-term viability and profitability of these facilities.

However, the exact consequences of an AI bubble burst are uncertain and depend on various factors, including technological advancements and market dynamics.

9. Are they/will they become military targets?

While data centres are critical infrastructure, they are not typically considered military targets. However, the increasing importance of data centres in the AI-driven economy and their potential role in critical systems could make them more vulnerable to cyberattacks or other forms of disruption. As such, data centres may need to implement enhanced security measures to protect against potential threats.
