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 fitted out a van 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.
Armed with enthusiasm to make a practical difference and strong social media skills,   Marchesi and Patchett quickly expanded the service to Melbourne, Sydney and the Gold Coast.
Their charity Orange Sky Laundry - named after one of their favourite songs - now operates in 36 locations and washes 350 loads each week. Over 270 volunteers have joined up, and governments and local businesses have come on board to make the charity more sustainable.
Last year, they expanded their mobile laundry service to natural disaster areas in North Queensland. This year they want to keep opening in new locations across the country, giving more Australians access to something many of us take for granted: clean clothes.
