As part of the Northam Health Service redevelopment, the hospital has had its first patient treated at the new surgical services unit.
The opening of the first stage of the unit marks another milestone in the hospital's $42 million redevelopment.
WA Country Health Service regional director Sean Conlan said the unit included two new operating rooms and sterilising services.
The second stage of the work within the surgical services unit is scheduled to be completed later this year and will include the reception and waiting area, change rooms and staff offices.
"This is part of a raft of improvements to the hospital, which are all benefiting the residents of our local and surrounding communities by allowing them to receive first-class care closer to home," Mr Conlan said.
Other recently completed areas include the new emergency department and a new ambulatory care building that provides access to community health services including physiotherapy, speech therapy, occupational therapy, counselling, community health nursing, community mental health and aged care support.
Cancer services will receive a boost with a new chemotherapy centre being redeveloped as part of a Commonwealth government-funded program.
Mr Conlan said construction of a new satellite renal service was also well advanced.
He said the renal service is funded by the state government as part of WA Country Health Service's capital works program improving hospital infrastructure.
The WA Country Health Service is currently overseeing the biggest transformation of country hospitals and health facilities in more than a generation valued at $1.5 billion over 10 years.
