Multiplex has topped out Stage Two of NEXTDC’s P1 Perth data centre, installing the largest satellite antenna array in Western Australia.
Located at 4 Millrose Drive in Malaga, north of Perth’s CBD, the five-level building represents the fifth data centre Multiplex has been contracted on by the ASX-listed Australian tech giant.
Stage Two of P1 Perth will double the data centre’s current IT capacity. The build is highly technical, with complexity added by working next to the operational building delivered in Stage One.
Now that Stage Two of P1 Perth has reached its tallest point, Multiplex will commence fit-out of the building’s plantrooms, offices and new data hall. Future works include the fit-out of two more data halls, plus expansions to central plant and services infrastructure.
Chris Palandri, regional managing director of Western Australia at Multiplex, said the team was proud of the milestone.
“We have worked on five data centres around Australia over the last seven years, representing over 500MW of total IT capacity,” said Palandri. “The technical nature of this project has required meticulous construction. It reflects our experience delivering intricate projects in live, sensitive environments and our ability to mobilise our specialist workforce.”

Stage Two of P1 Perth has seen 95 workers on site each day, with a combined 154,055 hours worked on the project so far.
Sustainable construction practices are driving the project’s delivery, with Multiplex using an electric crane on site to lower emissions. Green concrete has also reduced embodied carbon emissions by 65 per cent compared to conventional cement mixes.
Prefabricated components such as risers, header pipework and reinforcement cages are being used to minimise waste and enhance efficiency. A focus on local procurement has also seen Multiplex switch from imported materials to locally sourced aluminium and precast panels.
In addition, P1 Perth has been designed to meet a minimum 5-star WELS water efficiency rating.
Social inclusion has been a key focus on site, with Multiplex engaging 100 per cent Indigenous-owned Rigsafe as its rigging partner. Multiplex also created career pathways by upskilling local trainees and creating promotion opportunities for apprentices within subcontractor teams.
Practical completion of Stage Two is scheduled for the third quarter of 2026.
