Alexander Island
- Lower Collie River, Australind WA 6232
- Not open to the public
The small 5.4-hectare island forms part of the Kalgulup Regional Park and provides a refuge for local and migratory waterbirds.
For conversation reasons, it is not open to the public. However, it can be viewed by boat or from a lookout point within the Clifton Community Reserve.
The island was part of a 120-hectare land grant to George Leake of Greenwood Farm in 1839. Because it was located in the middle of the river, it was left in a relatively undisturbed state.
In 2005, it was recognised as an essential wildlife habitat and purchased by the State Government for $110,000.
