Nauru Detention Center

His comments come as a Somali refugee remains in a Brisbane hospital after she and her newborn son were medically evacuated from Nauru in a critical condition.

Ian Rintoul, from the Refugee Action Collective, said 22-year-old Naima Ahmed was 32 weeks pregnant when she underwent a caesarean section operation on Thursday.

The ABC understands Ms Ahmed has been taken off life support and her condition is slowing improving.

Mr Dutton said on Saturday there were "significant numbers of medical staff" on Nauru who provided care to asylum seekers in detention.

The Refugee Action Collective said the 22-year-old woman known as Naima and her baby boy were flown in separate planes.

Ian Rintoul from the advocacy group said Naima underwent a caesarean operation on Nauru on Thursday and the baby was born one month premature.

He said an air ambulance transported Naima to Brisbane and a plane carrying the baby left Nauru three hours after his mother.

Dr Barri Phatarfod from Doctors for Refugees said the mother was on life support.
