This year marks 40 years since the creation of the .au domain within the global domain name system.

For four decades, .au has been a core part of Australia’s national infrastructure, underpinning our digital society and economy, and enabling internet users to easily and accurately access websites and email addresses ending in .au.
In the first decade of operation .au amassed around 4,000 .au domain names. Over the intervening period, digital communications, services, trade and commerce grew rapidly.
Today, that 4,000 has grown to more than 4.3 million .au’s supporting Australian businesses (com.au and net.au), not-for-profits (org.au), education providers (edu.au), community organisations (asn.au), local, state and federal government departments (gov.au), and individuals (id.au).
Like other technologies, .au has evolved over time. In the early 2000’s, the commercialisation of the internet, increased use of PCs at home, schools and workplaces, coupled with changes to the .au rules, made in consultation with our multi-stakeholder community, led to significant growth in .au domain name registrations. Since then, auDA has introduced new security protocols, moved the .au registry to the cloud, and continues to refine the .au Licensing Rules so they support Australians and their evolving online needs.
While most people are familiar with domain names, which are the visible part of the .au domain name system (DNS), the DNS operates behind the scenes. Despite this, it’s foundational to the internet’s operation. Every website visit, online transaction and digital interaction – from banking, healthcare, education and government services – rely on the DNS to translate human readable domain names into Internet Protocol (IP) addresses.
Forty years on, the role of the .au domain is more important than ever, providing a stable foundation for digital innovation and communications. As new digital platforms and technologies such as Artificial Intelligence (AI) applications emerge, they also rely on the DNS.
.au’s 40 year milestone is not just an opportunity to reflect on how .au’s operations have evolved and supported Australia’s digital economy and modern communications needs, but also to consider how we can continue to ensure secure, reliable and trusted digital infrastructure that will support innovation into the future.
Trust and security in a changing digital landscape
As digital systems become increasingly interconnected, and society’s dependence on digital systems expands, so too does the importance of protecting them. Cyber threats are evolving and system complexity is increasing. Yet individuals, governments and businesses need assurance that their online presence and the digital services they provide and rely on are secure and resilient.
In 2024, auDA published its Future Scenarios Project Report exploring how geopolitical and environmental forces could shape society by 2044 through three plausible future scenarios.
The scenarios are not predictions. They were developed with input from local and global experts to help us navigate current uncertainty and prepare for alternate outcomes.
Across the three scenarios, the internet continues to be regarded as essential infrastructure. While it is too soon yet to determine which elements of the scenarios may come to fruition, it is clear that the decisions made today will shape how secure, trusted and reliable the internet remains, which is critical to shaping our future society and economy.
Governing for uncertainty, not certainty
The Future Scenarios Project highlights that the future is far from predictable. We know the digital environment is likely to be shaped by AI, national security and climate events. The three scenarios built upon these uncertainties by also considering the interplay of corporations, international institutions, social platforms, and the economy, justice, science, politics and education systems, and how they will shape our on and offline environments.
Governing digital infrastructure will increasingly require the ability to operate in an uncertain environment. Many of the key challenges in the scenarios, including online trust, digital identity and the governance of AI enabled systems, span multiple sectors and jurisdictions.
Multi-stakeholder internet governance, a model in which auDA advocates and actively participates, provides a framework to tackle complex, cross-border challenges. It brings together governments, industry, technical experts, academia and civil society to identify robust, well considered, inclusive solutions in the long term public interest.
Strengthening digital resilience
Another key theme in the scenarios is the growing importance of digital resilience. Exposure to cyber security risks increases as our reliance on digital systems deepens.
The future scenarios report explores how national security concerns may drive greater fragmentation of digital infrastructure, and how global institutional cooperation may become increasingly relied upon to manage shared risks.
This highlights the importance of sustained investment in the foundations of the internet. Strengthening security protocols, supporting research into emerging risks and maintaining robust governance will be critical to preserve trust. A clear example of this is auDA’s investment in research by Deakin University to support the transition to a quantum-safe DNS.
It is also vital that society’s trust in the internet as a tool of social and business connection, is maintained. To this end, auDA invests in research to understand how Australian’s use the internet and is investing in research to better under the drivers of trust in the online environment.
Another way we contribute is by working with industry partners and government on crisis preparedness and response. Scenario planning, cyber security exercises and cross sector coordination help identify vulnerabilities before they can be exploited, build collective capability and support faster recovery if and when incidents occur.
By taking a long term, collaborative approach to resilience, auDA, as the administrators of the .au, can better navigate an increasingly complex digital environment and support those in our ecosystem to do the same.
