Kingpin of Australia's adult toy industry Malcolm Day has begun raising money for what he claims will be the 'world's biggest brothel', a three-storey 42-room mega-sex-complex opposite Sydney University on the city's Parramatta Road.

"The new complex will create the largest short-stay bordello globally. On completion, earnings are projected to double to 40 million dollars of revenue and 12 million dollars of EBITDA," according to a stockbroker presentation obtained by BusinessDay.
