Some vulnerable Vic kids skipping school

Some children in Melbourne are skipping school because they don't have the money to pay for public transport, a study shows.

Victoria University operates a clinic at the Sunshine Youth Legal Centre where about 50 per cent of clients seek help with fines for not having a valid Myki or a valid concession card.

"For children who are vulnerable ... sometimes if they get a fine or don't go to school because they don't have money, they face violence in the home," the university's Su Robertson said.

The study, which will be reviewed by the Victorian government, proposes public transport be free for children going to and from school.
