Shark Island - Sydney Harbour - Port Jackson - New South Wales
Shark Island is the long, low green strip you notice when the ferry swings into Rose Bay — about a kilometre from the bay’s mouth, and small enough that a picnic rug can feel like half the island. NPWS spells the Aboriginal name Boowambillee (older records also use Boambilly). It sits on Gadigal Country as part of the harbour’s fishing and foreshore cultural landscape; keep that general unless youre citing Traditional Owners directly.
The English name is usually tied to the island’s shark-like outline. Yarns about sharks drawn to slaughtering waste still circulate — colourful, but treat them as popular lore, not gospel. Colonial and Federation governments bounced the place between quarantine and public recreation until public pressure helped lock it in as a reserve around 1900. Under the Clark Island Trust and later the Sydney Harbour Trust, Edwardian picnic kit arrived: paths, seats, shelters, and those sandstone foreshore grottos that still look like someone planned a holiday for the tide.
Shark Island joined Sydney Harbour National Park in 1975. It’s still one of the best 360-degree lunch spots on the harbour, and a favourite perch for watching the Sydney to Hobart fleet leave (the 1945 first race is linked with a start off this stretch of water). No scheduled ferry — private boat, water taxi or selected cruises, and a landing fee applies, same regime as Clark and Rodd.
