Twelve-year-old Perth girl, who was born this month, was impregnated with her 14-year-old half-brother.
In the shocking sequence of events, the father of a healthy child lived in the same house as a girl when she became pregnant at the age of eleven years.
It is understandable that the girl did not know she was pregnant until she started working in a home in Perth's home.
She was later admitted to the King Edward Memorial Hospital where she gave birth to a healthy baby.
A community spokesperson said he is working closely with the police and the Ministry of Health to ensure the well-being of all three children.
"The department is not able to comment on such situations to protect the privacy of individuals and their families," said the spokesperson Western Australian .
Previously, the department confirmed that the young father was "known" to a young mother.
Western Australian police commissioner Chris Dawson said the situation is centered on social security.
"It is a very sensitive and sensitive situation, but we were mainly interested in ensuring the right support mechanisms," he said.
"Although there is a police investigation, it is primarily focused on well-being."
The community department said they did not comment on individual cases, but a coordinated response was required from the state administration and external support agencies in the short and long term.
According to the Health Department, in 2017, WA bore three girls aged 13 or less, with a similar figure for 2016.
In total, 91 women aged 16 years or younger and the youngest registered mother who were 12 years old were born in 2017.
Twelve twelve-year-old girls gave birth to WA since 1980.
The department notes that birth rates have fallen from 1.2% in 1980 to 0.3% in 2017.
Federal Aboriginal Health Minister Ken Wyatt said he was "concerned" because he knew the young mother would not experience normal childhood.
"She will not have the same path as any of us in this room who went from being a child, to a teenager, to a young adult, and then able to better inform decisions," he told reporters in Perth.
"However, I have no doubt that her family will give her her subordinate support – but she does not do it right."
