From London: The next generation of mobile networks is taking shape in laboratories and standards committees across three continents, and the geopolitical stakes are unmistakable. As Australians slept this week, industry bodies and national governments were mapping the technical foundation for a technology that will reshape wireless connectivity in the 2030s. The question facing Canberra is whether the country will help write those specifications or watch from the sidelines.
6G networks are expected to arrive around 2030, succeeding 5G as the sixth generation of mobile infrastructure. But this is not merely incremental progress. 6G merges wireless access, artificial intelligence, edge computing, and sensing into a single continuum, creating a fundamentally different approach to connectivity than its predecessor.
The technical ambitions are extraordinary. 6G is projected to achieve speeds between 100 Gbps and 1 terabit per second, making it approximately 100 times faster than 5G, with potential download speeds enabling a full-length 8K movie in seconds rather than minutes. But raw speed tells only part of the story. 6G radios will measure distance, velocity, and environment characteristics while transmitting data, creating a perceptive network that enables precise localisation for autonomous mobility, infrastructure monitoring, and situational awareness.
Here lies the innovation that separates hype from substance. Where 5G excelled at moving large volumes of data, 6G embeds sensing capabilities directly into the radio spectrum itself. This means networks become not just connective tissue but active sensors, capable of detecting and tracking movement, environment, and objects without dedicated infrastructure.
The standardisation process is advancing rapidly. The International Telecommunication Union released framework recommendations for 6G development in 2023, with 3GPP technical studies underway to define technical specifications. During June 2025 meetings in Prague, the leading members of the ICT industry initiated 6G technology studies, with work lasting 18 to 21 months beginning in August 2025. Ericsson expects the first 6G specifications to be completed by the end of 2028, enabling the first wave of commercial deployments in 2030.
The timing creates an uncomfortable reality for fiscal prudence. Countries that invest early in standards development gain disproportionate influence over the technical trajectory. Those that remain passive risk finding themselves locked into standards shaped by others. China understands this calculus clearly. The largest number of 6G patents have been filed in China, and China's approach represents a coordinated, top-down strategy integrating government policy, academic research, and private sector innovation, with the Ministry of Science and Technology leading an official 6G R&D initiative since 2019.
Australia has not been entirely absent. In February 2024, the United States, Australia, Canada, the Czech Republic, Finland, France, Japan, South Korea, Sweden, and the United Kingdom issued a joint statement endorsing shared 6G principles for open, global, and secure connectivity. This positions Australia alongside Western democracies committed to preventing the technical fragmentation that plagued 5G.
Yet endorsing principles differs from funding research and developing sovereign capability. Australia is investing AU$10 million to fund the establishment of a 6G research and development programme under the Digital Economy Strategy 2030. While non-trivial, this is modest against the strategic scale of the challenge. The United States, China, South Korea, the European Union, and Japan are all investing heavily. Germany has allocated 700 million euros for 6G research through its Federal Ministry of Education and Research. Canada and Ericsson announced a $470 million investment in R&D centres focused on 5G and 6G, a strategic move to position Canada as a key global research hub.
The comparison speaks to a broader strategic vulnerability. Australia still needs a comprehensive strategy or national policy for utilising 5G and 6G, which may become a hurdle to realising the full potential of these technologies, with 6G and wireless communications needing to form part of a broader national strategic framework encompassing the entire government.
There are legitimate counterarguments to aggressive public investment. 5G revenue growth has disappointed market projections, and private companies have already committed substantial capital to 6G development. Why should taxpayers fund research that vendors will eventually commercialise? The answer lies not in raw investment but in influence. Standard-setting organisations like the 3GPP make decisions by consensus among members. Nations represented by strong local research communities and equipment manufacturers have louder voices.
Consider the practical implications. Australia's telecommunications strategy includes early 6G planning, with Telstra announcing in March 2025 that 6G is expected in the 2030s, with $800 million set aside to improve existing infrastructure over four years. Telstra's commitment is substantial, yet a single operator, however large, cannot by itself influence global standards architecture.
The stakes extend beyond commercial advantage to security and resilience. Geopolitical competition during the rollout of 5G continued to shape the development of 6G, with these developments affecting early 6G planning and global supply chains. If 6G technical choices become entrenched by 2028 without substantial Australian research input, the country may inherit an architecture not optimised for its unique geography or security posture.
For a country with vast distances, sparse population density in regional areas, and critical infrastructure spread across the continent, technical choices matter acutely. Telstra's 6G submission specifically referenced the need for always-on emergency connectivity and coverage over the entire Australian continent, proposing tight integration between terrestrial and non-terrestrial networks from the outset of 6G development. That Australia has operators thinking strategically about these requirements is encouraging. That those requirements must be argued in international forums without corresponding government-backed research support is a vulnerability.
The sensible path forward is neither isolationist paranoia nor uncritical enthusiasm. Australia should treat 6G standardisation as it treats spectrum allocation: as critical national infrastructure requiring coordinated engagement. That means adequate funding for university research partnerships, support for Australian participation in 3GPP technical working groups, and integration of 6G planning into the formal policy frameworks that guide infrastructure investment.
The technology itself is neither inherently friend nor foe. What matters is who builds it and on whose terms. Australia has a narrow window, closing quickly, in which to ensure the terms favour its interests. Fiscal caution and strategic ambition are not contradictory when the stakes involve sovereignty over fundamental networks.
