St Agnes Surgery was founded by Dr David Gill in 1967. He was joined by Dr Murrell in 1969.  The practice was then  relocated to the newly constructed St. Agnes Shopping Centre.

A population ‘explosion’ in the north eastern suburbs of Adelaide saw a rapid expansion of the practice. To accommodate increasing patients and staff, the building underwent major redevelopment in 1979 and 1986.

Professor Murrell left the practice in 1981 to establish the University Teaching General Practice Unit at Highbury.

Tea Tree Surgery opened in 1987 and functions as a fully equipped complimentary service.

​On the 3rd July 2000, St Agnes Surgery and the St Agnes Medical Centre moved to their current purpose-built location, on the site of the old Shell service station on North East Road, opposite the St Agnes Shopping Centre. 

​All of the facilities previously available in the St Agnes Medical Centre were also been relocated.

​We are also pleased to have additional services in the new centre, including  hearing services, podiatry, Australian Clinical Labs (pathology), St. Agnes Physiotherapy and a range of Medical Specialists.

St. Agnes Surgery has been designed to provide the most up to date facilities with a special children's playroom incorporated within a modern patient waiting area. A feature of the surgery is an enhanced treatment area with four treatment rooms, a nurse’s station, a privacy room for patients and six consulting rooms.

The surgery is fully computerised, with an upgrade of our computer system taking place at the time of the relocation and periodically since. Our current clinical software package (Medtech32, soon to be Medtech Evolution) enables us to utilise many features including "decision support" systems and advanced "search" capabilities. St Agnes was the first practice in Australia to introduce this computer software.
