Dotted through the space, which is set on a steep hill that rolls down to Sydney Harbour, are sculptures and many other endearing artefacts. Once you reach the garden’s centre, you’ll also find chairs and benches to be perched upon as you soak up the wonderment. Bird baths, cherubs, an ancient wheelbarrow and a metal fountain from the late Margaret Olley, another iconic Sydney artist, await amid a manicured mass of palms, shrubs and trees.
