Cicada x Tech23 2025

Australia’s biggest deep tech event

10th September 2025, Sydney

As the biggest deep tech event in the country, Cicada x Tech23 is not just a showcase but a movement. A movement to champion 23 visionary founders, connect them with the right people, and accelerate their journey from lab to market, from startup to scale.

The 2025 Tech23 cohort is tackling challenges from cancer diagnostics and green steel to synthetic biology, precision agriculture, and quantum satellite navigation. These ventures represent the best of Australian deep tech: bold ideas backed by world-class science, and a mission to build a more sustainable, secure, and sovereign future.

Themes for Cicada x Tech23 2025

The Built World, Upgraded

From self-monitoring infrastructure to energy systems that respond in real time, these startups are embedding intelligence into the physical world - redesigning how we live, move, and power a planet under pressure.

Re-Sourcing the World

Startups in this session are redefining where value comes from transforming carbon, waste, and critical minerals into the raw materials that will power a climate-conscious, resource-constrained future.

A New System of Care

This session reveals how healthcare is shifting from reactive to preemptive, with sensing, diagnostics, and monitoring systems that act before symptoms appear, building a future where health is continuous, ambient, and engineered.

Built with Biology

These ventures are using biology as infrastructure, harnessing living systems to grow, fabricate, and regenerate everything from industrial materials to ecosystem intelligence.

Engineering New Capability

This is deep tech that enables the impossible: sensing, navigating, and operating in environments beyond the reach of legacy systems, from autonomous flight to quantum-scale perception.

Global Innovations. Made In Australia

Everyone has a role to play at Cicada x Tech23. We bring together the deep tech village - investors, industry leaders, and policymakers - to connect with the founder solving the world’s biggest challenges. Great ideas don’t scale alone. Tech23 is where you meet the founders, forge partnerships, and shape the future of deep tech in Australia.
