Melbourne local Michael Tanner earns anywhere from $800-$1100 each month by renting out his Ford transit van.
Tanner rents it out three-four days per week and makes a profit of $500-$700 per week after registration and vehicle expenses are factored in.
“I’ve got a late-model van that I use off and on for carting plants around. Most of the time it’s empty, so it has worked out very well,” he told News Corp.
“It’s good for me as a small business. I don’t frequently need it but when I need it I just book it.”
The cars cost around $4 an hour or $20 a day to rent.
