The much-delayed Perth Children's Hospital (PCH) is in the middle of a staged opening before it is fully operational in early June, beginning to see outpatients last week and with plans to commence elective surgery next Monday.

The $1.2 billion hospital's emergency department will open on Sunday, June 10, when the old Princess Margaret Hospital (PMH) closes. PCH is using the iCM clinical information system from DXC that is still in use at PMH and Royal Perth.
