Heirisson Island is an island in the Swan River in Western Australia at the eastern end of Perth Water, between the suburbs of East Perth and Victoria Park. It occupies an area of 285600 m2, and is connected to the two foreshores by The Causeway. The next upstream island is Kuljak Island, then Ron Courtney Island, with no islands in the Swan River downstream between Heirisson Island and the Indian Ocean other than the artificial islet in Elizabeth Quay.

The Swan River Colony, also known as the Swan River Settlement, or just Swan River, was a British colony established in 1829 on the Swan River, in Western Australia. This initial settlement place on the Swan River was soon named Perth, and it became the capital city of Western Australia.
