When an adolescent leaves school early, they're more likely to end up homeless than their peers at school — and to be struggling with issues later in life.

In Geelong, Victoria, 250 young people leave school early every year and about 230 of them seek help for homelessness.

But a new early intervention model adopted by 'The Geelong Project' has seen results in turning this trend around already — and its interim report is out today.

It found that youth homelessness could be reduced by 40 per cent, the risk of school disengagement halved and early school leaving reduced by more than 20 per cent.

The report's author, David MacKenzie, believes these results could be seen nationwide if this approach is adopted.
