Jonny Warren is taking part in next week's Vinnies CEO Sleepout, but doing it in a way that reminds him of his own time sleeping rough on the streets, as a young man addicted to ice.
Now a successful real estate agent and doting father, Jonny is a long way down the track from where he was. But he doesn't forget those days.
On Thursday, June 18, he will be joining other CEOs and community leaders sleeping outside at the Museum of Australian Democracy in Canberra to raise money for Vinnies. But he's taking his campaign a step further. Quite a few steps.
