Extremely rare identical girl quadruplets born at Royal Brisbane and Women’s Hospital

Royal Brisbane and Women’s Hospital has delivered four spontaneously conceived identical quadruplet girls, sharing one placenta and split from one singular fertilised egg – an unprecedented occurrence.

The remarkable pregnancy was extremely high risk for proud mum Jenitar and her four beautiful daughters, Emily, Harriet, Alexa and Catherine who were delivered via c-section at 28+4 weeks on 14 July 2026.
The mum of eight, who has four existing children aged between 10 and one years of age, had not planned another child – when she and her husband naturally conceived the quadruplets, taking them by immense surprise.
She has been monitored and cared for by an enormous team of experts at Royal Brisbane and Women’s Hospital since 10 weeks and was admitted as an inpatient at 25 weeks so she could be monitored.

RBWH Maternal Fetal Medicine Specialist and Obstetrician Dr Alexa Bendall has been caring for Jenitar since she first discovered she was pregnant, acknowledging both how enormously high-risk and rare the quadruplets were, and how well Jenitar had handled the news.

“Jenitar has taken everything in her stride from day one – we have never seen a spontaneously conceived pregnancy of this type with quads, and she has somehow dodged every complication and risk for both herself and her babies to be here today, with four gorgeous newborn girls,” Dr Bendall said.

“Monozygotic quadruplets are estimated at one in every 15 million pregnancies, but to share the same placenta, this is unheard of.

“We always said that if we could get her to 28 weeks, we would be doing well, so we are happy she could make it to this gestation.

“The rare quadruplets will now spend time in our specialist RBWH Neonatal Intensive Care Unit (NICU) where they will grow to full term and are currently doing extremely well.”

34 year-old Jenitar Sau Na’amoana and her husband Jortham will now navigate life with their growing family, spending time between home and the RBWH NICU while their babies get stronger.
