For decades, mobile libraries have brought books into the lives of those who would otherwise go without. Meals on Wheels has helped feed those who cannot cook for themselves. What no one had thought of was creating a mobile laundry to wash the clothes of the homeless. That was until September 2014 when best mates Nic Marchesi and Lucas Patchett, both 21, decided to give it a go.

"We wanted to improve the hygiene standards of the homeless, so we came up with this crazy idea of building a free mobile laundry," Marchesi said last year.

It started small. The Brisbane boys took an old van nicknamed Sudsy, fitted it out with a generator, water tanks and two large washing machines and driers. Then they started driving around town offering to clean the clothes of those sleeping rough. Often they would park their laundry near food vans and free barbecues, allowing the homeless to have their clothes washed while waiting for a feed.
