Coolart Wetlands and Homestead Reserve, Nature reserve and historic homestead in Mornington Peninsula, Australia.

Coolart Wetlands and Homestead Reserve is a nature reserve on the Mornington Peninsula that combines wetland areas, woodlands, and open grasslands. A Victorian brick mansion with a distinctive turret sits at the center of the property as the main historical building.

Coolart began as a pastoral lease taken up in 1839 by brothers Alfred and Henry Meyrick on Bunurong land. The two-storey brick homestead was built between 1896 and 1897 for Frederick Sheppard Grimwade, a Melbourne businessman and parliamentarian, as a family country retreat. From 1937 Thomas J. Luxton created the homestead garden, wetlands and a private wildlife reserve, and persuaded the Victorian government to declare the property a wildlife sanctuary. The government bought Coolart in 1977 for conservation and education, and Parks Victoria took over management in 1996.

The place takes its name from Bunurong words that relate to the land itself. Today visitors experience this cultural connection when walking through the grounds and learning about what the area meant to its original people.

The reserve is open daily with parking near the entrance and pathways throughout the grounds for easy movement. Public transport connections from nearby stations provide good access for those traveling without a car.

A plaque in the grounds honours Graham Pizzey, author, photographer and ornithologist, who served as Coolart's first warden from 1980 to 1984. The woodlands also shelter koalas, swamp wallabies and echidnas, animals many visitors overlook while watching the ibis colony.
