Clark Island - Sydney Harbour - Port Jackson - New South Wales 

Clark Island is the tiny bush knuckle off Darling Point — less than a hectare, close enough to Double Bay that you feel you could almost swim the gap on a calm day. Early colonial sources record Aboriginal names including Billong-olola / Be-lang-le-wool; modern visitor material also uses Billong-Olo-Lah. It sits on Gadigal Country and was used for hunting and gathering shellfish along the eastern harbour foreshores.

In 1789 First Fleet officer Lieutenant Ralph Clark tried growing vegetables here. In a hungry colony, theft of the crop became a running joke — and a headache — but the name “Clark Island stuck. Later in the nineteenth and early twentieth centuries, like neighbouring Shark Island, it was pulled into public recreation planning: trusts and harbour authorities laid paths and picnic amenity without sanding off the rocky bush character.

Today NPWS runs it as a day-use picnic and event site with a ridiculous view west to the Opera House and Harbour Bridge. There’s no public ferry timetable. You arrive by water taxi, private boat or cultural tour — Tribal Warrior Aboriginal cultural cruises are among the groups that land here. Landing fees and group caps apply; sunrise to sunset is the usual window. Pair it with Shark and Goat (Me-mel) if you’re doing the harbour islands as a set.
