Dr Patricia (Trish) Symons is a perinatal pathologist and staff specialist in Anatomical Pathology at NSW Health Pathology’s Liverpool laboratory. Each day Trish and her colleagues play a crucial role in supporting the care of mothers and babies across the growing south-west Sydney region.
Perinatal pathology focuses on the examination of the placenta and the period surrounding birth.
Since being given the opportunity to formally report placentas in 2018, Dr Trish Symons has developed a strong passion for placental pathology, with particular interests in obstetric hysterectomies and Placenta Accreta Spectrum Disorders.
Her work supports clinicians by providing valuable insights into pregnancy complications.
Dr Symons and her team based at Liverpool Hospital examine large numbers of placentas each year, many from babies requiring care in neonatal intensive care units or special care nurseries.
“Most of our babies are in the NICU or special care nursery, and the placenta can give clinicians important insights into what’s been happening during the pregnancy.”
Giving back through research and teaching
Alongside her diagnostic work, teaching is a big part of Dr Symons’ role.

Working within a large public teaching hospital allows her to supervise and educate registrars, contribute to case based learning, and support interdisciplinary collaboration.
She has written guidelines and protocols for her department and regularly presents at clinical case review meetings.
“Teaching is such a significant aspect of a big public hospital like Liverpool and I don’t think it’s recognised enough,” she said.
“That teaching ability is one of the things that sets us apart.”
Dr Symons is also involved in placental pathology research. She is currently part of a collaborative research project with UNSW, where she holds a position as Conjoint Lecturer. While placental pathology has been the subject of extensive research over many years, she says there are still unanswered questions.
“Placental pathology has had a lot of research over the years, but it hasn’t necessarily translated into what we really need to report day to day,” she says.
“The placenta can tell an important story about what’s happening during a pregnancy. There’s still a lot we’re trying to understand.”
The importance of partnering
Her commitment to ongoing learning and professional development was recognised recently when she received a prestigious Royal College of Pathologists of Australasia (RCPA) award, which allowed her to spend two weeks at The Austin Hospital in Melbourne.

Dr Symons says the visit reinforced the importance of collaboration, teaching and expert consultation when managing complex perinatal cases.
She plans to bring those insights back to NSW Health Pathology by strengthening diagnostic consistency, sharing knowledge with colleagues and supporting education and research within the Liverpool laboratory.
Dr Symons says one of the most rewarding aspects of her role is the strong professional support network across the public health system.
“If I have a difficult case, I can send it to the Children’s Hospital and they are fantastic,” she says. “That connected network is really important.”
For Dr Symons, it’s the combination of patient impact, teaching, research and collaboration that makes her work so rewarding.
“The ability to do research in conjunction with universities and to teach at the same time is a really important part of being a public teaching hospital.”
Through her expertise and commitment to research and learning, Dr Trish Symons continues to make a meaningful contribution to patient care and the future of perinatal pathology in NSW.
