Sydney Adventist Hospital provides complete care for most forms of cancer including specialised radiation therapy. The Radiation Oncology Institute (formerly Sydney Radiotherapy & Oncology Centre) is located within the grounds of Sydney Adventist Hospital and is one of two treatment centres owned and operated by a dedicated team of cancer specialists.  The second centre is located in Gosford.


The Radiation Oncology Institute features two modern linear accelerators, simulator and computerised Three Dimensional (3D) planning system, including IMRT, to customise radiation therapy for each patient. The 3D planning system provides the means to accurately calculate conformal radiation therapy that is delivered using the linear accelerators. For the patient, this means a more defined radiation dose to the tumour and lower doses to healthy tissues. This is aimed at higher success rates for tumour control and less side-effects from treatment.

The latest in radiotherapy machines was installed in the Wahroonga practice in 2005.  These Linear Accelerators enable delivery of conformal therapy using features such as MultiLeaf Collimation (MLC) and Electronic Portal Imaging (EPI) to ensure a more accurate dose delivery and treatment of a tighter tumour volume.  A similar machine was installed in Gosford in 2003, ensuring both Centres are capable of providing the most advanced radiation therapy programs.


Country patients who require a weekly radiotherapy program can be accommodated on the Hospital grounds at Jacaranda Lodge


Specialist Radiation Oncologists prescribe the treatment that is delivered daily by the Radiation Therapists. Specialist Registered Nurses and administration staff complete the team to provide a comprehensive cancer service aimed at reducing the stresses and difficulties normally associated with such an intensive treatment program.

The Radiation Oncologists are:

Referrals and Fees

GP or Specialist referrals are required for Radiation Therapy consultation. Most radiation therapy can be given on an out-patient basis. Fees are therefore rebated by Medicare, in-part, for most patients. Private Health Funds only reimburse part of the costs if the patient is admitted to hospital for the duration of the treatment. Discounts are offered for early payments and terms are available for those requiring time to pay. Eligible Repatriation patients are not charged for consultation or treatment as fees are paid for by the DVA.


The Radiation Oncology Institute is conveniently located on the ground floor of the Shannon Building, (Level 3) Sydney Adventist Hospital. The Institute is accessed through the first Hospital entrance near Fox Valley Medical & Dental Centre (see map).  Designated parking is available for radiotherapy patients directly outside.

Further Information

Consultations are available Monday to Friday from 8:30am to 4:00pm.
Treatment appointments are made after planning has been arranged and treatment is available between 7:15am to 4:30pm.
