Optus Stadium


Brookfield Multiplex


Perth, Australia

Completion date


The Westadium consortium was appointed by the Government of Western Australia to design, build, partially finance and maintain the new 60,000 seat Optus Stadium and Sports Precinct.

Optus Stadium is a world-class multi-purpose venue, using an innovative 'fans first' design. The $1.6Bn multi-purpose venue has been designed to accommodate a wide range of uses including AFL, cricket, rectangular field sports (rugby, soccer), athletics, and entertainment events. The impressive 60,000 seats places the stadium in Australia’s top three venues for audience capacity.

Marshall Day Acoustics worked collaboratively with Westadium to provide advice on bowl acoustics, environmental noise, room acoustics and mechanical and services noise. Full Details. For more information on the Optus Stadium, visit the website here.

The Stadium 

The new Perth Stadium features roof coverage of more than 85 per cent of seats, a bronze facade that reflects WA's unique geology, LED lights that can display home sports team colours, and a wide range of 'fan first' facilities, including two of the largest video screens in the country and 4G Wi-Fi coverage for spectators.

Our Brief

Our brief includes design advice for the broadcast cabling infrastructure services, AV systems design review and the main sound system. The sound system design incorporated the main bowl, public concourses and external public circulation spaces (including entry gates).  Numerous individual coverage zones were provided throughout the building to enable the Stadium control room to address one or many zones.  Digital audio was distributed via a converged site-wide ICT network (with dual redundancy).  All sound systems were designed as integrated SSISEP (EWIS) systems, negating the need for a separate EWIS system.
