Telstra International’s Sarah Mills on AI Networks, Operational Resilience, and APAC’s Digital Growth
Sarah Mills, the global head of wholesale at Telstra International, shares insights on AI-driven autonomous networks, the expanding digital landscape in the Asia-Pacific (APAC) region, and Telstra’s contribution to global connectivity.
Telstra has long focused on building a reliable, high-capacity network that supports new technologies and evolving customer demands. In APAC, this means enabling fast digital growth through autonomous networks, smart cities, and satellite connectivity. Recently relocated to Singapore from senior roles in the UK, Mills leads Telstra’s initiative to help businesses and individuals succeed in the digital economy.
What Makes the APAC Digital Market Unique for Telstra
The APAC region is undergoing significant digital transformation, but its vast size and diverse markets present challenges. For 25 years, Telstra International has established a strong subsea network presence here, extending to cable landing stations, network operating centres, and terrestrial backhaul into data centres with colocation services.
Supported by its Australian hub, Telstra innovates to support this diverse region. Mills points out the complexity of dealing with multiple countries, each with distinct cultures, regulations, and practices. Telstra’s longstanding footprint allows it to help many businesses access and grow within these markets.
Demand is surging, driven by emerging markets and a young, digitally savvy population, especially in Southeast Asia. This creates new opportunities as global customers invest in the region. Hyperscalers are also partnering locally, accelerating the expansion of digital infrastructure across the supply chain.
Mills highlights that many areas remain underserved, whether due to geographic challenges or geopolitical and economic factors. Telstra’s role in improving connectivity in these regions is a key part of its strategy.
Driving Critical Connectivity with AI
Telstra International prides itself on agility, supported by secure multi-segment subsea infrastructure and an extensive network footprint. AI is now transforming how critical connectivity is delivered.
Mills explains that AI enables customers to simulate and orchestrate their network before investing physically. This approach simplifies procuring infrastructure and controlling capacity while making networks more proactive, secure, and resilient.
With cyber threats and geopolitical uncertainties rising, network resilience and security are crucial. Telstra uses AI to build autonomous networks that maintain uptime and protect against cyberattacks. This approach not only improves efficiency but also ensures customers get secure, reliable service when needed.
Refocusing on Network Infrastructure for Digital Innovation
The telecommunications sector is shifting its focus back to core network infrastructure. After years of trying to position themselves as broad technology service providers, telcos are now emphasizing their foundational strength: reliable connectivity.
Mills notes a trend where customers may choose to purchase infrastructure and technology services separately instead of bundled solutions. This shift is supported by innovations that give customers more control and easier orchestration of their technology.
This renewed focus on infrastructure reflects the understanding that secure, resilient foundations are essential for mission-critical applications. Mills sees this as a major industry change expected to unfold by 2030.
Building a Digital Future in APAC
Mills sums up Telstra’s vision as enabling individuals and businesses to thrive in the digital economy through solid digital infrastructure.
Australia serves as a key anchor, offering geological stability, power capacity, and renewable energy initiatives to support data centres. Additionally, Telstra supports satellite constellations to deliver connectivity to remote and underserved areas.
This layered approach to infrastructure is vital for delivering digital services across APAC, helping the region’s markets and customers reach their full potential.
