About Sydney · October 2026

October is a warm-up in Sydney, and the real weight lands in December. Ascend on Oct 13 is the first big name, Google Cloud and DeepMind's AI and startup festival, and Atlassian for Startups runs its demo night on Nov 4. The main draw is NeurIPS on Dec 5, the first edition held outside the northern hemisphere, with AI Engineer Sydney the day after and AI Investor Sydney on Dec 10.
