Advertisement More than half of Australians support the minimum age of criminal responsibility being raised from 10, amid a growing international campaign for the change backed by legal experts, doctors and justice groups. In fact, polling commissioned by Amnesty International Australia reveals two-thirds of Australians already believe the minimum age of criminal responsibility is 14. A total of 56 per cent of Australians would support raising the minimum age to 14, with 33 per cent opposed and 11 per cent unsure, the polling suggests. The survey came as the Queensland government begins public hearings into contentious youth justice reforms and after 31 United Nations member states called on Australia to raise the age in line with other jurisdictions.
