The Canberra Airport is this year hosting the Vinnies CEO Sleepout but the bosses won't be cosying up in the terminal with coffee on tap.
They will be sleeping in breezy Hangar 47 at the Fairbairn RAAF base, where the airport says temperatures regularly fall to below freezing and "aircraft noise will be a constant reminder of the harsh realities of sleeping rough".
This year's event on June 20 hopes to raise $700,000 just in the ACT to help fund services for the homeless.
Last year's sleepout was at the National Museum.
