What 58,000 users taught us: Lessons from Australia's only national AI platform for students and staff

In October 2024, CEnet launched cechat — a purpose-built AI platform for Catholic education. Seventeen months later, it is Australia's only national AI project that places students and staff side by side on the same platform, at scale. Embedded within 370 institutions, with 2500+ purpose-built agents, and 118,000+ conversations logged, the data set is rich and the lessons are real. This session shares what worked, what surprised us, and what we'd do differently. It features a short walk through of the hard-won insights from designing, deploying, and governing AI across organisations spanning metropolitan, regional, and remote communities in Australia.Key lessons explored include: why curriculum alignment determines whether AI tools get used; why hierarchical governance (HQ → diocese → school → classroom) was non-negotiable for earning trust with parents and regulators; what happens when students actually use AI in a walled garden with real-time content flagging and escalation pathways; and why the platform that wins isn't always the most complex, it's the one educators trust enough to put in front of children. This is not a product pitch. It's a frank account of building the only national AI platform where a Year 5 student practising narrative writing and a principal assessing excursion risk are on the same system, governed by the same framework, and supported by the same architecture.
