Connectivity
Network connectivity underpinning Australian AI workloads: submarine cable capacity, international latency, and domestic backbone bandwidth.

Australia's geographic isolation creates unavoidable latency to US/EU data centres. This fundamentally constrains AI workloads that rely on offshore inference.
Bandwidth Over Time
Connectivity Context
Australia is served by multiple submarine cable systems. The Southern Cross NEXT and Indigo cables provide highest-capacity routes.
Average broadband speed: — Mbps (median, fixed line). NBN coverage ~96% of premises.
Sovereignty implication: AI API calls routed offshore carry data sovereignty and latency risks. Local AI inference avoids both.
