Geelong Anaesthetic Group

The Geelong Anaesthetic Group (GAG) is Geelong’s original group practice in the medical speciality of anaesthesia. It exists to provide anaesthesia, pain management and intensive care services to the Geelong community.


The group originated with Dr Geoffrey Darby, who was the city’s first specialist anaesthetist.  He gained his D.A. in Melbourne in 1956, and his Fellowship of the Faculty of Anaesthetists of the Royal Australasian College of Surgeons in 1957.  In the mid-1960′s, Dr William Crosby and Dr Richard Hallowes were invited to join him. After much discussion their association was named, and it became known in the medical community as “GAG”. Each of the founding three doctors was at some stage Director of Anaesthesia, and Director of Intensive Care at the Geelong Hospital. Over the decades Geelong Anaesthetic Group has grown with the city and surrounding region it serves.  There are currently 14 members, supported by five office staff.  Initially the group had an informal structure, but in September 1989 it was incorporated and became Geelong Anaesthetic Group Pty Ltd. First located in the grounds of the Geelong Hospital, the group moved  in 1987 to nearby premises in Swanston Street, where it remained for 12  years. From early 2000 to June 2009 the  group was located at Suite 8 De Garis House at Geelong Private Hospital.  We are currently located at Suite 5, Level 2 of the new St  John of God Specialist Centre, directly across the road from St John of  God Hospital.
