After being evacuated from Sydney’s south coast because of the bushfires, we’ve relocated to Palm Beach for a family reunion of sorts. I pity the poor residents because no less than six different Joye family units have descended on this enclave for the break.

As a fund manager, I’ve naturally been doing my bit to save humanity, whipping the search and rescue drone up and down the coast hunting for sharks zeroing in on surfers and swimmers. During one recent flight I received a call from an individual known simply as the “waterboarder”, a mentor who chairs a multibillion-dollar hedge fund, among other things.
