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

Snapper is the smallest island in Sydney Harbour — a ship-shaped scrap off Drummoyne and Birkenhead Point, sitting with Cockatoo and Spectacle in the western harbour. Early colonial wordlists record an Aboriginal name Ar-ra-re-agon. For most of the nineteenth century the rocky islet saw little permanent building; it was declared a public recreation reserve in the late 1870s and then barely visited.

World War I leased it for storage tied to Cockatoo Island Dockyard. The silhouette everyone notices today dates from 1931–32, when Leonard (Len) Forsythe of the Navy League had the rock blasted, levelled and expanded by reclamation into Training Depot “Sydney” (TS Sydney) for naval cadets. TS Sydney opened in November 1932. Seawalls were cut to suggest a ship’s bow and stern; buildings followed a deck-like plan a land-locked training ship pointed at Drummoyne. Parts salvaged from HMAS Sydney I when she was stripped at Cockatoo helped furnish the memorial idea.

TS Sydney ran as headquarters for Sydney Navy League units for decades. The island is on the Commonwealth Heritage List for Forsythe, the cadets, and that odd harbour skyline contribution. Structures have weathered; the museum collection moved (including to Spectacle and Garden Island) around 2006. Unlike Spectacle’s explosives complex, Snapper’s significance is cadet training, not magazines; access stays tightly managed.

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

Off Drummoyne, tucked with Cockatoo and Snapper in the old Hen and Chickens” group, Spectacle Island is the harbour’s quiet explosives cousin — the one most Sydneysiders only clock from a ferry or the Anzac Bridge approach. An Aboriginal name recorded in early colonial wordlists is Gong-ul. The European story is almost entirely powder and armament: Australia’s oldest naval explosives manufacturing and storage complex, with fabric from the 1860s still sitting on the rock.

From the early 1860s the colonial government put a gunpowder magazine here. Victorian Georgian buildings associated with Colonial Architect James Barnet — magazine, laboratory, cooperage, guard and residential structures — form the nineteenth-century core. In 1884 the island went to the Royal Navy as an ordnance depot for the Australia Squadron; in 1913 it passed to the new Royal Australian Navy and kept feeding ammunition lighters through both world wars and into the late twentieth century.

Spectacle Island is a Commonwealth Heritage place. It is no longer an operational ammunition pipeline and remains largely closed to the general public. A Naval Repository of RAN relics sits among the buildings. Together with Cockatoo and Snapper it reads as a tight brick-and-sandstone industrial pocket that never became a picnic lawn — and that is the point.

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

Stand on the Potts Point side of Woolloomooloo Bay and Garden Island still reads as a low green hump under the navy’s cranes — except it stopped being a true island generations ago. Aboriginal names recorded in early sources include Ba-ing-hoe / Booroowang (Navy histories also cite Bayingawuwa). Within weeks of the First Fleet’s arrival in 1788 the rock was cleared as a vegetable garden for HMS Sirius — standard Royal Navy anti-scurvy practice. The ship’s log for 11 February 1788 already calls it “the garden island,” and the English name stuck. Sandstone initials dated 1788 survive as rare physical scraps of that first year.

After decades of ships’ gardens and intermittent official use, the mid-1850s turned the place into a serious Royal Navy depot on the Australia Station. In 1913, when the first Royal Australian Navy fleet unit arrived, Admiralty control passed to the Commonwealth. Two world wars thickened the yards into Australias principal fleet base and ship-refitting centre. The Captain Cook Graving Dock, built in the Second World War, joined the former island permanently to the Potts Point mainland — the land bridge you still see when a ferry rounds Garden Island ferry wharf.

Today the precinct is Fleet Base East / HMAS Kuttabul: a working naval establishment with nationally significant heritage fabric, not a picnic island. Public access is restricted; heritage interpretation runs through Navy and related historical societies rather than a casual landing.

 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.

 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.

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

 Goat Island (Me-mel) - Sydney Harbour - Port Jackson - New South Wales 

Most harbour ferries slide past Me-mel — Goat Island — without stopping. That’s half the point of the place. It sits almost in the middle of Port Jackson, a sandstone knuckle of magazines, barracks, wharves and quiet bush that never became a picnic lawn like Shark or Clark.

Aboriginal people have known it as Me-mel (also written Milmil and similar forms in early records). Colonial writers linked it with the family of Woollawarre Bennelong; today’s NPWS material keeps Me-mel front and centre. From the 1830s the colonial government took over in earnest: water police, convict labour along the shoreline, then magazines and workshops that kept the island a working harbour machine well into the twentieth century. The State Heritage Register listing covers that whole layered mess — Aboriginal, historic and natural — not just a pretty outline on the water.

What’s left is denser than most visitors expect: buildings and structures from the 1830s through to the 1960s, including a Harbour Master’s residence from 1902. NPWS manages the island inside Sydney Harbour National Park while a government-backed process works toward Aboriginal ownership and governance of Me-mel. Remediation and conservation are underway; public access has always been tighter here than on the picnic islands. Check NPWS before you assume you can land.

 Pinch Gut Island - Fort Denison - Sydney Harbour - Port Jackson - New South Wales 

That stubby Martello tower off the Botanic Garden isn’t a postcard prop — it’s Fort Denison, still better known to many Sydneysiders as Pinchgut. Colonial sources record Aboriginal names Mat-te-wan-ye / Muttewai and related spellings; NPWS today also uses Muddawahnyuh. Governor Phillip called the rock Rock Island soon after 1788, but “Pinchgut” won: usually tied to convicts left out here on bread and water, and sometimes to the harbour’s narrow pinch itself.

American warships sailed into the harbour unchallenged in 1839, which concentrated minds. Levelling for a fort began in 1841, then stalled. Crimean War jitters about a Russian attack restarted the work in the mid-1850s. Colonial engineer George Barney oversaw the battery and Australia’s only Martello tower, finished in 1857 with stone from Neutral Bay and named for Governor Sir William Denison. It never fired in anger. The design was already half out of date when the paint was still wet.

From the late nineteenth century the island earned its keep as a light and tide station. A time gun — moved from Dawes Point in 1906 — fired daily at 1 pm so ships could set chronometers; tide measurement has run from here for well over a century. In World War II a shell from USS Chicago, firing during the Japanese midget-submarine attack, damaged the tower. Since 1995 the fort has sat in Sydney Harbour National Park. Check NPWS alerts before you plan lunch on the bastion — conservation closures are not rare.
