Airlie Morris and Bill Bunnage are the owners of Ha Ha, a property located approximately 10km southeast of Ballan. The property is a dedicated wildlife sanctuary also used for agriculture, and it is Airlie and Bill’s intent to continue forestry, honey farming, and eco-tourism endeavors on Ha Ha.
The property totals 83 hectares formerly used for grazing, abutting the Werribee Gorge State Park and part of the western grassy plains and woodlands ecosystem. Wildlife species known to inhabit the sanctuary include eastern grey kangaroos (Macropus giganteus), swamp wallabies (Wallabia bicolor) and wedge-tailed eagles (Aquila audax).
