New Maternity Assessment Unit opens Enhanced obstetric and rehabilitation services McGowan Government election commitment nears completion Expectant mothers have been delivered a huge baby bonus with the opening of a new Maternity Assessment Unit (MAU) as part of the $24.9 million expansion of the Osborne Park Hospital. As part of the expansion project, the MAU will enhance the hospital and health care experience of thousands of northern suburban parents who require enhanced obstetric services. The MAU consists of four built-for-purpose assessment rooms and three assessment bays for expectant mothers attending Osborne Park Hospital for birth. Staffed by doctors and midwives seven days a week around the clock, the MAU provides a service for women who may have started labour or may require additional monitoring during their pregnancy.
