A surrogate in Australia is making global headlines after giving birth to twins, with one of them being her own, biological child. The two babies were not genetically related; one was biologically related to the intended parents paying the woman to carry their child, and the other was the biological child of the surrogate and her husband.

Key Takeaways:

• A surrogate in Australia learned she was pregnant with twins, but one of them was biologically hers.

• After giving birth, she was able to take her biological son home, while the intended parents of the other child brought their baby girl home.

• However, surrogacy law in Australia prohibited the children's separation until a judge formally allowed it.

• This is not the first time such a case has unfolded, highlighting the ethical questions surrounding surrogacy.

The Details:

The couple who hired the surrogate, known as BNJ and DRJ, was unable to conceive naturally due to medical reasons, and in September 2024, began working with DZ as the surrogate mother for their baby.

DZ was implanted with one embryo from BNJ and DRJ in April 2025. However, two weeks later, an ultrasound showed two babies — one boy and one girl. Genetic testing was carried out, and it was revealed that the baby girl was the biological chid of the intended parents, and the baby boy was the biological child of DZ and her husband FZ.

According to court documents, DZ "conceived separately to the... embryo implantation process, and without medical assistance."

When the twins were born in November of 2025, the baby girl went home with her biological parents and the baby boy went home with his. However, the court had to intervene because under the Queensland Surrogacy Act, twins, triplets, or "birth siblings" are prohibited from being separated after birth.

According to LadBible, Judge Jode Wooldridge found that the babies were 'gestational twins' but not 'birth siblings,' as the law states. The court allowed the babies to remain with their biological parents.

Surrogacy and family lawyer Stephen Page told ABC, “The fact that the children were conceived separately means that they were not born as a result of the same pregnancy, and therefore they were not birth siblings, as defined in section 24 of the Surrogacy Act.”

The parents plan to ensure the children grow up knowing each other and having "an age-appropriate understanding of their place within the wider family network," according to a counselor hired for the families.

Zoom Out:

This is not a one-of-a-kind surrogacy story.

In 2016, Jessica Allen accidentally gave her own biological child to a Chinese couple who had hired her as a surrogate. Allen agreed to surrogacy in the hopes of saving money to buy a house. She underwent in vitro fertilization (IVF) in April 2016 and soon learned she was pregnant with twins.

"Not once during the pregnancy did any of the medical staff provided by the agency say that the babies were in separate sacs. As far as we were concerned, the transferred embryo had split in two and the twins were identical," Allen told the New York Post.

When she gave birth via c-section in December, she didn't get to see the babies, but the following day, the intended mother showed her a photo of the babies.

“Wow! They look different,” Allen allegedly told the intended mother.

Later, the intended mother wrote to Allen saying, "They are not the same, right? Have you thought about why they are different[?]"

DNA tests soon revealed that the boys were not biologically related to each other.

Allen learned that the intended parents said they didn't want the baby that wasn't "theirs," and the agency was actively looking for someone to adopt the baby. Shockingly, would-be adoptive parents were expected to pay the intended parents $18,000 to $22,000 that they wanted in so-called "compensation" for the baby boy.

Allen and her husband, Wardell Jasper, hired an attorney and were able to get their son back; an employee from the agency brought the baby to them at a Starbucks two months after his birth.

"It was the first time I saw my son [in person] — and it took place in a Starbucks parking lot," she said, adding, "I missed two months of my son’s life. Those first few weeks of bonding are so important and we were robbed of them.”

"Wardell and I... weren’t planning to expand our family so soon, but we treasure Malachi with all our hearts. I don’t regret becoming a surrogate mom because that would mean regretting my son. I just hope other women considering surrogacy can learn from my story. And that a greater good will come out of this nightmare," said Allen.

The Bottom Line:

These stories highlight the ethical questions surrounding IVF and surrogacy, which deny the dignity of children and women, treating them as commodities to be bought and even sold.

The children conceived in IVF are tested, graded, and labeled; some of them are destroyed for not making the cut.

In these two stories, the parents were ultimately able to have custody of their biological children, but there are stories with more controversial endings.
