Perth Data Centres: A Buyer's Guide for Western Australia

Why Perth is its own data centre decision

Perth is the main data centre market in Western Australia. For organisations with users, staff or operations in WA, the question is rarely whether Perth has suitable facilities. It is which facility fits, and what role it should play: your primary site, a second site for disaster recovery, or a hub that links regional operations to the cloud.

That decision looks different from the same choice in Sydney or Melbourne. Perth sits a long way from the other mainland capitals, it faces Asia and the Indian Ocean rather than the Pacific, and much of its demand is shaped by the resources sector.

This guide focuses on what is specific to buying in Perth. For a list of mapped Perth sites and operators, see our Colocation in Perth page (/colocation-perth). It is general information only, and facility details change often, so confirm anything you rely on with the operator.

Perth facility options at a glance

Two national operators publish detailed information about their Perth sites. NEXTDC runs P1 in Malaga, about 13 km north-east of the CBD, which it describes as Uptime Institute Tier III certified, and P2 in the Perth CBD, which it describes as Tier IV certified. The two are linked by NEXTDC's data centre interconnect services. NEXTDC also operates two smaller Tier III edge sites in the Pilbara: NE1 in Newman and PH1 in Port Hedland.

Equinix operates three Perth sites, PE1, PE2 and PE3. PE2 at Shenton Park is the landing point for two international subsea cables, and Equinix describes PE3, its newest Perth site, as directly connected to key subsea cables.

They are not the only choices. The DChunt map also lists Perth sites from operators including Vocus, CDC Data Centres and STACK Infrastructure, along with a number of smaller local providers, spread between the CBD, inner suburbs and outer industrial areas. You can browse them on the map (/map) and read operator profiles in the provider directory (/providers).

Isolation and latency: what distance means for WA buyers

Every request between a Perth user and a server in Sydney or Melbourne has to cross the continent and back. For email or back-office systems that is rarely noticeable. For interactive applications, virtual desktops, voice, trading or real-time control systems, it can be.

A simple rule works for most buyers: host systems close to the people and machines that use them most in real time. If the bulk of your users are in WA, a Perth site usually makes sense for those systems, even if other workloads stay on the east coast. If you are unsure, test from real user locations instead of relying on published figures, and ask providers for measured latency on the routes you care about.

Distance also affects day-to-day operations. If your IT team is based interstate, factor in travel time for installs and incidents, and look closely at each facility's remote hands service.

The same distance can work in your favour. A Perth site is far removed from east coast facilities, which makes it a natural option for a geographically separate disaster recovery location. Our disaster recovery guide (/learn/disaster-recovery-first-time-buyers) explains how to set recovery targets before you choose a second site.

Asia subsea links and national routes

Perth is Western Australia's gateway for international subsea cables. The Australia Singapore Cable, built and operated by Vocus and in service since September 2018, runs between Perth and Singapore with connections to Christmas Island and Indonesia, and lands at Equinix PE2. INDIGO West also links Perth and Singapore via Jakarta, with its terminal equipment reported to be hosted in NEXTDC's P1 and P2. The Oman Australia Cable, which also lands at PE2, connects Perth with Muscat, and Equinix has described it as positioning Perth as Australia's connection point to Europe.

Domestically, INDIGO Central links Perth and Sydney, and SUBCO announced in June 2026 that its SMAP cable linking Sydney, Melbourne, Adelaide and Perth was ready for service. Together with terrestrial fibre, these systems give carriers more diverse paths across the continent.

For buyers, the practical point is this: a cable landing in Perth does not mean every Perth facility has equal access to it. If Asian markets or diverse international routes matter to you, ask which carriers deliver capacity on which cable systems into the specific building, whether you can get two genuinely separate paths, and how cross connects are priced. Our guide to connectivity choices (/learn/connectivity-choices-explained) covers the questions to ask.

Cloud access from Perth

The full public cloud regions serving Australia are all in eastern Australia, but Perth now has smaller local extensions. AWS launched a Local Zone in Perth in January 2023, and Microsoft announced an Azure Extended Zone for Perth in December 2024, which has since been listed as generally available. Both bring a subset of compute, storage and networking services closer to WA users, while relying on a parent cloud region elsewhere in Australia.

Private connections matter too. NEXTDC says P1 hosts local on-ramps for AWS Direct Connect and Microsoft Azure ExpressRoute that customers in P2 can reach, and Equinix says its Perth sites provide access to major cloud providers and their on-ramps.

If you are planning a hybrid setup, check two things early: whether the specific cloud services you need are available locally or only in the parent region, and where your private connection actually lands. Our guide to cloud on-ramps and hybrid cloud (/learn/cloud-on-ramps-and-hybrid-cloud) explains the options.

Mining and resources workloads

The resources sector shapes a lot of Perth's data centre demand. Major miners run their WA operations from Perth control rooms. BHP's Integrated Remote Operations Centre has operated from its St Georges Terrace office since the end of 2012, and Rio Tinto says its Perth Operations Centre runs autonomous trucks, trains, plants and drills across its Pilbara mines, ports and rail from about 1,500 km away.

When operations are run remotely, the data centre becomes part of the operational chain, not just the IT department's concern. Resources businesses, and the contractors and service firms that support them, usually need to think about resilient and diverse network paths between Perth and remote sites, predictable latency for monitoring and control systems, and separation between operational technology and corporate IT.

Some processing is better done close to the mine or port, where links can be limited and conditions are harsh. That is the role NEXTDC positions its Newman and Port Hedland edge sites for, with Perth facilities acting as the metro core. Large survey, geoscience and sensor datasets can also push up storage and power needs, so plan for growth rather than buying for today's footprint alone.

Shortlisting checklist for a Perth data centre

Start with role. Decide whether Perth will be your primary site, a disaster recovery site for east coast systems, or a hub for regional operations. That choice changes what matters most.

Work out power per rack. Estimate your kW per rack now and in three years, then confirm each facility can support it in the hall you would occupy.

Check connectivity in the building, not the city. List the carriers, subsea systems and cloud on-ramps you need, and confirm they are available at the specific site.

Ask for evidence. Request current certifications, recent audit reports and the operator's service levels for the building you are buying into.

Plan for access and support. Confirm remote hands hours, response times and escalation, especially if your team is interstate or on a roster.

Compare like with like. Shortlist two or three sites, view them on the map (/map), see how Perth compares with other cities on our coverage page (/coverage), and line them up side by side with the comparison tool (/compare).
