A 12-year-old boy left Kendall, on the NSW Mid-North Coast, and travelled one third of the way across the country in a car before being stopped by police in Broken Hill.
The boy was pulled over on Saturday morning after completing more than 1300 kilometres of his journey.
A NSW Police spokesman said the boy was on his way to Perth.
He was stopped by Highway Patrol officers at about 11am when they noticed his car's bumper was dragging along the ground.
"Officers from Broken Hill Highway Patrol stopped a motor vehicle on the Barrier Highway due to defects which made the vehicle hazardous," the spokesperson said.
"Checks revealed the driver to be a 12-year-old boy travelling from Kendall NSW on his way to Perth," the spokesperson said.
The boy was arrested and taken to Broken Hill police station. Police said inquiries into the boy's situation were continuing.
