The state government is considering overhauling the public transport system for low-income school students.

The radical shake-up of public transport was announced by Public Transport Minister Jacinta Allan in response to a report to be launched on Tuesday, which urges the government to overhaul the public transport fine system for young people.

"Current concession fares significantly reduce the cost of travelling for students, but we recognise that, for the most disadvantaged, even a small fare can have a big impact," Ms Allan said. "We are currently reviewing the ticketing enforcement regime to ensure it is fair for all, particularly for those kids who have the least and need public transport the most."

Public transport fines are a fact of life for many children from low-income backgrounds.
