Sydney Colocation Space

Sydney is Australia's financial capital and the natural landing point for transpacific submarine cables (Southern Cross, INDIGO, Hawaiki). It hosts 65% of the country's planned data center capacity, the headquarters of major banks and insurers, and AWS Sydney + Azure Australia East + GCP Sydney all anchor in the metro. Supply is structurally tight relative to AI-driven demand from AWS, Google, Microsoft and Oracle.

North Sydney CBD is for financial services and government tenants who need physical CBD residency — premium pricing. Macquarie Park is the tech corridor — strong enterprise ecosystem at NEXTDC S1/S2, lower than CBD pricing. Western Sydney (Eastern Creek, Erskine Park) is for hyperscale and AI workloads — best $/kW, larger footprints, good fibre paths to CBD.

AirTrunk's Sydney facility at 130 MW and 376,737 sq ft — the largest in Australia. AirTrunk's broader Australian portfolio is the country's biggest by capacity, followed by NEXTDC and CDC.

Increasingly, yes. AirTrunk SYD1 and CDC's Eastern Creek campuses are designed for liquid cooling and densities of 50-100 kW per rack. Power constraints in inner Sydney push most large GPU deployments to Western Sydney where land and grid capacity are more available. STACK Infrastructure and Vantage are building greenfield AI-ready capacity.

IRAP (Information Security Registered Assessors Program) is the Australian government's data security framework. Many Sydney colocation buyers require IRAP-assessed facilities, particularly for federal, state government and defence-adjacent tenants. Most major Sydney operators (CDC, AirTrunk, NEXTDC, Macquarie) have IRAP-assessed sites.

We'll match you with capacity across Sydney's tight supply landscape and surface AUD pricing, redundancy levels and AI-readiness for like-for-like comparison.
