An investigation has begun after confirmation a girl in Western Australia gave birth at a hospital earlier this month.

Authorities in Perth have confirmed a 12-year-old girl has given birth at a hospital.

Local media report the girl became a pregnant when she was 11 and had her baby earlier this month.

Jackie Tang, of the Department of Communities, would not comment specifically on the case to protect the girl's identity, but told Community News it did work closely with multiple agencies when a young mother gave birth.

"A co-ordinated response is required from a range of State Government and external support agencies both in the short and long term in order to make a lasting difference to the wellbeing of all affected parties," she said.

"The Department of Communities, the WA Police and Department of Health work together intensively in the best interests of all concerned.

WA Health Department statistics show that since 1980, there have been 12 registered births to girls aged 12, the youngest registered age of a birth mother in WA.

In 2017 there were three registered births to girls aged 13 or younger, seven registered births to 14-years-olds and 21 registered births to 15-year-olds.

The most publicised case of a young mother in recent years is Britain's Teresa Middleton who gave birth aged 12.

Middleton was made to give up her daughter when it was revealed the child was a result of rape by her brother.

Now 25, Middleton has since had a son with her fiance and hopes one day her little boy can meet her daughter.
