The CEO Sleepout will be held in Sydney, Newcastle and Wollongong on 23 June, as well as in other cities around the country.
CEOs across the country are raising funds to raise awareness about homelessness and the lack of affordable housing in Australia.
Almost $1.25 million has been raised so far, of which nearly $300,000 is from 291 Sydney leaders.
Over 105,000 Australians experience homelessness each year. For just one night, business and community leaders will give up the comfort and safety of their beds at home to get a glimpse of what it means to be homeless.
