Children as young as six years old are being forced into child marriage in Australia, with more than 100 cases of forced child marriage are currently being investigated by the Australian Federal Police.

Obtained under the Freedom of Information laws by Seven News, data shows that since January 2017, 171 cases of forced child marriage have been investigated by the AFP, with experts saying children forced into marriage are often too terrified to alert authorities to seek help.

Missing from the data is the amount of children born in Australia who are taken overseas to be married, with experts calling for a considerable review and investment into the issue.
