Sydney: Australia’s cloud-native SaaS capital

Sydney is the commercial and technical heart of Australian tech. Atlassian still anchors a massive engineering presence here despite its US listing, Canva has scaled from a local design startup into one of the largest private software companies in the world, and Afterpay reshaped global buy-now-pay-later from its Sydney base. Around them, the big four — CBA, Westpac, NAB and ANZ — run some of the most ambitious enterprise AI programs in APAC, and Macquarie’s engineering teams push the bar on AI in capital markets. Add a healthy startup scene in Surry Hills and Barangaroo, and Sydney becomes a natural production market for applied AI.

Australian teams expect high engineering standards and pragmatic commercial framing. They are global by default.
