[1] Formerly located on Roberts Road in Subiaco, Western Australia, the hospital had approximately 220 beds and served 300,000 patients per year.

[2] PMH originated as the Perth Children's Hospital in 1909 after 12 years of community fundraising.

The original facilities included 40 beds, an operating theatre and outpatient department.

[5][6][7] In March 2021 major demolition works began at the former hospital site; however two heritage-listed buildings, Godfrey House and the Old Outpatients Building were preserved as well as the hospital's boiler house and chimney stack.

[8] The cleared site will then become part of the ongoing Subi East redevelopment.
