BROOKLYN BOAT TOUR FIELD GUIDE
Seven Islands of the Hawkesbury: A Riverboat Postman Cruise Between Sandstone Cliffs and a Naval Wreck
A three-hour, all-ages cruise from Brooklyn that traces Lion, Dangar, Spectacle, Long, Peat, Milson and Bar islands, passes water-access-only settlements and reveals the wreck of HMAS Parramatta.
Seven Islands of the Hawkesbury: A Riverboat Postman Cruise Between Sandstone Cliffs and a Naval Wreck.
The Hawkesbury River compresses scale and story into a single sweep: narrow channels edged by towering sandstone, small islands that read like chapters of local history, and settlements reachable only by water. The Seven Islands of the Hawkesbury cruise uncovers that layered landscape — and its human echoes — aboard the Riverboat Postman as it moves through the Lower Hawkesbury and past the wreck of Australia’s first warship resting beneath the cliffs.
