Nine years ago, the couple took early retirement and leased out their house in Somerville, south-east of Melbourne. They sold most of their possessions to travel the world by staying, for free, in other people鈥檚 homes.
Their next home might be a Paris apartment, or a house with stunning views on a Greek island.
Glenn estimates their three-week stay in one of their favourite places, a three-bedroom apartment on Fifth Avenue in Manhattan, New York, would have cost $AU18,000, had they had to pay.
Instead, they stayed there for free, in exchange for walking a Weimaraner dog in Central Park, two blocks away.
