Western Australia — Cockburn Sound, Gage Roads & Swan River (1830–1841)

The Admiralty chart that shaped Perth’s maritime gateway

This superb British Admiralty chart records the moment Western Australia’s principal harbour approaches were first unified into a single, authoritative navigation sheet. Originally surveyed in 1830 by John Septimus Roe—later Western Australia’s first Surveyor General—and updated through 1841 by Thomas Woore and John Lort Stokes, it captures Cockburn Sound, Gage Roads, and the entrance to the Swan River as they became safe, legible approaches for colonial shipping.

Engraved by J. & C. Walker and published by the British Admiralty, this was the working chart that underpinned Perth’s early maritime life—anchorage selection, pilotage, and river access.

This is not a decorative map.
It is the blueprint of Perth’s harbour approaches.

⚓ What This Chart Shows

This finely engraved Admiralty sheet delivers harbour-scale precision:

• Cockburn Sound with anchorages and approaches

• Gage Roads — the principal outer anchorage

• Entrance to the Swan River, the settlement’s lifeline

• Inset: Entrance into Cockburn Sound at enlarged scale

• Bathymetric soundings and isolines showing depths and hazards

• Coastal relief rendered with classic Admiralty hachures

• Greenwich prime meridian — true naval reference standard

🧭 Why This Chart Works

Most maps show where a harbour is.
This shows how ships actually used it.

• Authored by John Septimus Roe, a foundational figure in WA surveying

• Updated by Stokes and Woore, linking early settlement to mature hydrography

• True British Admiralty production — the global benchmark for accuracy

• High-resolution harbour detail essential for pilotage and anchoring

• Museum-grade engraving by J. & C. Walker
