A Queensland family has grown by four after Jenitar Sau Na’amoana delivered identical quadruplet girls at the Royal Brisbane and Women’s Hospital.
The babies—Emily, Harriet, Alexa and Catherine—were delivered by caesarean section on 14 July. They were born prematurely and received specialist neonatal care.
Metro North Health said the pregnancy was spontaneously conceived from one fertilised egg that divided into four embryos. All four babies shared a single placenta, making the pregnancy exceptionally complex and high risk.
How rare was it?
The hospital’s maternal fetal medicine specialist Dr Alexa Bendall estimated that a naturally conceived case of this kind may occur about once in 15 million pregnancies. The care team said it could be the first documented occurrence in Australia.
That figure refers to this particular type of identical, spontaneously conceived quadruplet pregnancy—not every quadruplet birth. Quadruplets overall are more common when assisted reproductive technology is involved.
The story attracted attention around Australia, but the family’s health and privacy remain more important than the novelty. The hospital described the mother’s pregnancy management as remarkable and said the babies arrived safely after extensive planning by a multidisciplinary team.
