Mobile Infrastructure Report 2023 Summary

This report analyzes changes in mobile infrastructure and coverage for Australia's major network operators (Optus, Telstra, and TPG) from 2018 to 2023, based on data from the Infrastructure Record Keeping Rules. Key findings include:

• Mobile Site Dominance: Telstra operated the most sites (up 300 since 2022), with significant presence in regional and remote areas, outpacing Optus and TPG. The gap between operators widened in remote regions, with Telstra having over 2300% more sites than TPG there.

• 3G Transition: Operators are phasing out 3G networks, with plans to complete shutdowns by late 2024. Telstra and Optus started significant reductions since 2022, and 2100 MHz spectrum is being repurposed for 4G/5G. Many 3G-only sites remain, needing upgrades to avoid service gaps.

• 5G Rollout: 5G deployment is accelerating, with Telstra leading in site count and low-band spectrum. By 2023, Telstra had over 57% more 5G sites than Optus and was expanding into regional areas. High-band spectrum usage is increasing but remains limited.

• Coverage Analysis: Significant differences exist between outdoor and external antenna coverage, with external antennas providing broader access. For example, Optus's outdoor coverage was only 83% of its external coverage, while Telstra's was around 52%. Regional and remote areas show notable disparities, with TPG lagging in coverage there.

• Methodology and Data: The report relies on data from infrastructure audits, noting challenges in comparing coverage due to varying models and a recent shift to including both coverage types. Co-contribution programs, like the Mobile Black Spot Program, play a key role in expanding networks in less populated areas.

This report highlights ongoing shifts in mobile infrastructure, emphasizing competition and investment trends across different regions and technologies.
