Four children packed fishing rods and money into a 4x4 before illegally driving themselves more than 900km across Australia.
The three boys and a girl ‑ all aged 10‑14 ‑ were discovered safe in the New South Wales town of Grafton.
One boy reportedly wrote a note to his family to say he was leaving.
Police said they would lay charges, but did not specify which ones.
The children were not all from the same family and had stolen the 4x4 from one of their parents.
A service station attendant told Police one of the boys was really short and could barely even reach the car window.
