OMNI is Sydney’s premiere gynaecological ultrasound service providing the highest quality imaging of the female pelvis for non-pregnant and pregnant women. OMNI is the first ultrasound centre of excellence in Australia which focuses primarily on gynaecological imaging and is dedicated to Endometriosis Ultrasound.

Endometriosis Ultrasound was introduced to Australia by OMNI’s Director, Associate Professor Condous, who is at the forefront of endometriosis and early pregnancy research.

Through advanced non-invasive diagnostics such as ‘deep endometriosis’ ultrasound or Sonovaginography (SVG) and Hysterosalpingo-Contrast-Sonography (HyCoSy), OMNI is equipped with the latest ultrasound technology and high-skilled personnel to deliver sound, professional service in relation to endometriosis and fertility assessment.

The introduction of SonoPODography (SPG) allows our experts to be the first group in the world to visualise superficial endometriosis.

OMNI’s 3D/4D advanced ultrasound technology allows us to provide expectant parents with a real-time view of their unborn child during the antenatal period. Our pregnancy scanning encompass all trimesters throughout pregnancy from early pregnancy dating and viability scans to late pregnancy fetal growth assessment.

latest 3D/4D ultrasound technology

Located in St Leonards, Somerset Hospital in Kingswood, Dee Why and in the Sydney CBD, OMNI is a centre of excellence for gynaecological and pregnancy scanning for women of all ages. Our comforting and friendly environment is fully equipped with the latest 3D/4D ultrasound technology and team of experts.

For expectant mothers, OMNI is available to expertly guide you through every stage of your pregnancy journey, from the beginning of the 1st trimester to the finale of the 3rd trimester and beyond. Antenatal care is important in helping to obtain the best possible outcome for both mother and child. Typically this involves a number of scheduled ultrasound visits on a regular basis to ensure optimum health for both you and your unborn child.

OMNI only accepts referrals made by either your GP or your Specialist. We provide you with high-quality expert transvaginal scanning, negating the need for exposure to radiation in the context of X-Ray and/or CT imaging. OMNI’s unique approach to non-invasive diagnostic ultrasound ensures your welfare and concerns are our top priority.


At OMNI we specialise in ultrasound assessment of the pelvis and fundamental diagnostic information for pregnant women. This not only reassures mothers-to-be about the health of their baby but provides those experiencing gynaecological complications critical information to enable immediate and appropriate informed planning.

With OMNI’s latest 3D/4D baby vision, you can watch your baby move in real-time and get a crystal-clear 3D view of their precious features, all before delivery. We can even provide keepsakes – copies of these amazing 3D images to share with family and friends, making this special time even more joyful.

Your 3D/4D experience with OMNI is all about creating lasting memories. We’ll make sure you have all the information about future ultrasound scans, so you don’t miss a beat. Share the wonder of your baby’s early development with loved ones in a truly special way.

OMNI uses the Tricefy mobile app for sharing digital images with patients. Available for both Android and iOS devices.


At OMNI we are aware that healthcare complications associated with pregnancy can occur without warning, and we are conscious of how traumatic and stressful these situations can be. This is why OMNI offers timely same-day ultrasound scans for women in urgent cases, which ensures the very best and expeditious diagnostic care.

OMNI’s ultrasound team incorporates the latest developments and approaches to create an individualised continuity of care program according to each woman’s specific needs and requirements.


Our warm and caring staff look forward to welcoming you to any of our four OMNI clinics operating in Sydney. Our Sydney CBD clinic is located on level 10 of the William Bland Centre, at 229 Macquarie Street; while our Penrith branch is located on Derby Street, adjacent to Nepean Hospital in Kingswood. We also have a clinic in St Leonards, on Northcote Street (near both the Royal North Shore and North Shore Private Hospitals) and the Dee Why Clinic on Dee Why Grand. Please note: all appointments made online or telephonically need to have an accompanying letter of referral from your GP or Specialist.

OMNI Ultrasound & Gynaecological Care

Condous performs Advanced Endosurgery procedures for women needing intervention for pelvic masses, adnexal pathology, severe endometriosis or hysterectomy. He also runs ‘Hands on’ Live Sheep Laparoscopic Workshops for gynaecologists at Camden Veterinarian School.
Having completed an undergraduate degree with the University of Adelaide, he left Australia in 1993 and moved to London where he completed his training in Obstetrics and Gynaecology. From 2001 to 2003 Condous worked as a Senior Research Fellow at St George’s Hospital, London. At St George’s he set up the Acute Gynaecology Unit, the first in the United Kingdom. It was also during this time that he developed an interest in Early Pregnancy and especially the management of pregnancies of unknown location (PULs). Condous has developed many mathematical models for the prediction of outcome of PULs which have been featured in numerous peer review journals. In 2005, he returned to Australia where he completed his Laparoscopic Fellowship at the Centre for Advanced Reproductive Endosurgery, Royal North Shore, Sydney.

Condous was appointed as a Consultant Gynaecologist and Senior Lecturer at Nepean Hospital in 2006 and soon was made Associate Professor. In 2010, he was made Departmental Head of Obstetrics and Gynaecology at Nepean Hospital. He obtained the MRCOG in 1999 and was made FRANZCOG in 2005. In 2009, he was awarded his Doctorate in Medicine (MD), University of London, for his thesis entitled: “The management of pregnancies of unknown location and the development of new mathematical models to predict outcome”.

Condous has edited three books including the “Handbook of Early Pregnancy Care”, published over 100 papers in international journals and is internationally renowned for his work in Early Pregnancy. He is the Associate Editor for Gynaecologic Obstetric Investigation, which is a European based journal, as well as the Australasian Journal of Ultrasound in Medicine (AJUM). He is on the organising committee and is an invited speaker at the International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG) Scientific meeting in Sydney 2013. His current research interests relate to the management of ectopic pregnancy, 1st trimester growth, PULs and miscarriage and the use of transvaginal ultrasound (in particular sonovaginography, to predict posterior compartment deep infiltrating rectovaginal endometriosis).Condous is also actively involved with post-graduate education including the annual running of the Early Pregnancy and Gynaecological Ultrasound Interactive Courses for Sonologists, Radiologists, Sonographers and Gynaecologists in Australia.
