Bring your binos but beware the ruse: Cooper Park is a misdirection, hiding the jewel with its French clue of Bellevue. Find the path and you'll adore the translation of a living landscape painting. Framed by blue sky and a descending green floor, the harbour opens like a Brett Whitely window. To the north, boats in Rose Bay sail by Shark Island; and to the east, Bondi headland greets the Pacific Ocean. Please tell no one, for this park is a gallery, and a secret worth keeping – whispered only by a breeze through its banyan trees.
