From the water, Spectacle Island sits in Sydney Harbour like the setting of an Agatha Christie novel. Abandoned buildings, rotting on the inside, pepper the small landmass. A gun turret sits rusting in the sun. Water snakes make their homes in the overgrown grass. The only humans to walk the old military outpost are a pair of guards who boat in for their shifts, patrolling 24 hours a day.
Sydneysiders are not allowed to roam the island, one of 13 that dot the harbour.
