The Oncall System


Dr Castner and Dr Mellor aim to care for their own patients during labour and delivery whenever possible. However, a back-up arrangement is in place for those situations when it isn’t, eg. performing a fertility or surgical procedure, family commitments or fatigue.

In general, Dr Castner is the on-call back up on Mondays and Wednesdays, and Dr Mellor on Tuesdays and Thursdays. Friday back up alternates between the two doctors from week to week. Weekend cover is shared with Dr Vincent Loh and Dr Shane Higgins, with whom Megan and Amy have previously worked at Arrivals Obstetric Centre. The weekend call is covered from 6pm Friday evening until 7am Monday morning, though a woman’s primary obstetrician will still provide care in this time period whenever feasible.

On occasions your doctor may be called to the Birth Suite at a time when you are scheduled for an appointment. Your consultation may be delayed, or you may be asked to reschedule for later in the day or on a subsequent day. We apologise in advance if this occurs, and ask for your patience and understanding. Be reassured that when you are in labour or require immediate attention, you will be your doctor’s first priority.
