An Australian entrepreneur has spent more than two full days on the toilet to raise money for a new business venture.

''It's borne out of using disgusting toilets myself and being concerned for my own personal hygiene. It's a much, much higher risk for people who live in those circumstances.''

Simon Griffiths, 29, has been on the toilet for 51 hours in an attempt to raise $50,000 to fund the first production of his socially-responsible toilet paper - Who Gives A Crap - which he plans to sell and split the profits 50/50 with WaterAid.

He then plans to build toilets in places in the developing world that are desperately in need of improved sanitation.

He said: ''It's borne out of using disgusting toilets myself and being concerned for my own personal hygiene. It's a much, much higher risk for people who live in those circumstances.''
