What is now the tallest building in Midland is finally at its full height following construction of the brick and metal facade.
The detailed internal fit- out of wards and treatment areas is now under way.
Health Minister Kim Hames said the hospital was progressing on time and within budget.
‘This hospital will deliver health care to 29,000 inpatients during its first year alone,’ he said.
‘This will provide the opportunity for people to access high-quality health care close to home for people living in Midland and surrounding communities,’ he said.
A fully equipped mock-up of an emergency treatment bay was on display last week for media and government representatives, and hospital staff.
The emergency section is expected to provide care to 55,000 patients in its first year.
Hospital chief executive Ian Anderson said the milestone confirmed progress was excellent.
‘Our project team can increasingly focus on the operational planning required to open the hospital, including the recruiting of more than 1000 staff,’ Mr Anderson said.
The public hospital will have 307 beds and the private section a further 60 beds.
State and Commonwealth governments have jointly invested $360 million in the project, with St John of God injecting $70 million.
