A spokesperson for the Department of Foreign Affairs has said the mother of a baby boy found in Queensland has been traced.
He added her family is in contact with the authorities and the matter is now solely a medical one.
Gardaí in the southeast have made contact with the woman and her family and are continuing to liaise with them.
Australian police were trying to trace the Irishwoman after a baby was found wrapped in a towel on Monday morning in a public toilet in Surfers’ Paradise.
The baby is thought to be just two to four weeks old.
Speaking on RTÉ Radio’s Morning Ireland, Tony Wilson, chief police reporter with Gold Coast Bulletin newspaper, said the baby is currently being cared for by Australian authorities.
Security footage, broadcast on Australia TV, showed a woman in her 20s leaving the building in Surfers' Paradise.
She is understood to have been identified by former housemates as an Irish girl who had been living on the Gold Coast.
Local media said Queensland police had confirmed with immigration that she had left Australia.
Australian police then contacted the gardaí to check an address she put on immigration papers when leaving the country.
The Department of Foreign Affairs has appealed for privacy for the family.
