Heirisson Island, over which the causeway runs, is thought to have been named after a crew member sailing with the French navigator-explorer, Captain Hamelin, in 1801. It occupies an area of 285,600 m2 (3,074,000 sq ft), and is connected to the two foreshores by the Causeway.
Today, Heirisson Island is the home to a colony of Western Grey Kangaroos, which can be seen in the enclosed southern part of the island. The statue of Nyoongar leader Yagan is also located on the island, which was a significant hunting ground for indigenous people. Yagan was a Noongar leader and resistance fighter during the early years of the Swan River Colony.
Known to the Nyoongar as Matagarup, meaning ‘leg deep’, it lends its name to the nearby pedestrian bridge.
Heirisson Island is roughly a 10-15 minute walk from the city centre and you can enjoy a picnic by the water’s edge at the many picnic tables, or simply enjoy a peaceful walk around the island.
