A colocation data centre hosts customer-owned hardware in an external secure environment, providing space, power, cooling, and physical security.
Telstra's colocation schedule lists inclusions such as space, power, remote hands assistance, and carrier cross-connects.
Capacity requirements for colocation, wholesale, and artificial intelligence workloads are matched to facilities manually, followed by direct operator introductions where both parties agree.
Submit a capacity requirement to evaluate matching facilities.
Australian cities and connectivity
Buyers should compare capital cities by facility-specific connectivity, cloud routes, and subsea cable access.
Sydney and Melbourne
In September 2025, Equinix announced its selection by SUBCO for the planned landing of the SMAP subsea cable system directly into its International Business Exchange (IBX) data centres in Sydney, alongside an SMAP Point of Presence (PoP) in Melbourne.
Brisbane and Queensland
NEXTDC describes its Brisbane facilities as providing a local Google Cloud on-ramp for direct hybrid connectivity.
Perth and Western Australia
In September 2025, Equinix announced its selection by SUBCO for the planned landing of its SMAP subsea cable system directly into its Perth International Business Exchange (IBX) data centres.
Colocation providers in Australia and facility infrastructure
Infrastructure designs vary across enterprise wholesale halls and retail colocation suites.
National facility footprints
Telstra InfraCo operates 7 data centres in Australia.
Cooling and power architecture
Buyers must verify rack-level power density against net IT load, evaluate cooling containment, and assess whether electrical and thermal systems meet resilience needs rather than relying on dual feeds alone.
Interconnection platforms
Software-defined fabrics streamline campus and metropolitan connectivity. The NEXTDC AXON network-as-a-service (NaaS) platform delivers dynamic software-defined connections that can be provisioned and decommissioned in seconds.
Specification and contract terms for Australian facilities
Structuring a procurement brief for Australian colocation facilities requires precise technical and commercial scoping.
Buyer requirement parameters
Procurement briefs must specify rack footprint, vertical rack units (U), kilowatt (kW) power draw, independent dual-feed redundancy, and power format (alternating or direct current).
Notice periods and price adjustments
Service schedules establish differing commercial modification periods:
-
Vocus specifies that it may review and modify service charges following increased costs with 10 days' written notice.
-
Telstra requires at least 30 days' notice before implementing schedule or pricing revisions at initial or renewal period end.
