"And sure enough, shortly thereafter, some security guards came on board to basically search whether another person would be hiding on the plane," Dr Babeck told host Carrie Bickmore.
He confirmed that none of the passengers had been told about the baby's discovery, and the women were given no indication as to why they were being asked to leave the plane.
"From what I understand, which is very frightening, many, if not all of them, were not told prior to their inspection what the reason for it was, so it only came out at the end when they reboarded … it must have been a terrifying ordeal, not even knowing what the purpose of this is," he said.
Bickmore, who described the incident as "deeply shocking" and "unfathomable", asked what the women's demeanour was like when they returned to the aircraft.
"Shell-shocked. Certainly the beginning. They were in disbelief, you know? You would have imagined this would have happened 100 years ago, but not now … One lady cried, others were certainly upset, but I think becoming angry in a mood to protest or to take action? That occurred much later," he said.
Dr Babeck went through the hotel quarantine process alongside the women from his flight after disembarking, and has kept in contact with them via a WhatsApp group. He said he was "utterly impressed" by how they've been coping.
"I have utmost admiration for them, because they have very strong personalities among them, different character, but I think united by the idea that this can never happen again, and that they would like to use their personal ordeal to make sure that people are made responsible for what has occurred, and that there is an investigation going on," he said.
Australia's Department of Foreign Affairs and Trade is waiting for a report from Qatari authorities into the incident, which Australian Foreign Affairs Minister Marise Payne described as "grossly disturbing and offensive" and unlike anything she "had ever heard of".
The incident has been reported to the Australian Federal Police.
