The Coolart Wetlands and Homestead Reserve, or just Coolart, is an 87.5 ha estate on the Western Port coast of the Mornington Peninsula of Victoria, south-eastern Australia, about 70 km south-east of Melbourne. It comprises a late 19th-century mansion-like homestead and surrounding grounds west of the village of Somers. The homestead is set in a garden with adjacent wetlands and coastal woodlands with walking tracks. It is managed by Parks Victoria and is open to the public. It is a popular venue for picnics, nature walks and birdwatching.
Coolart is bordered by Merricks Creek on the south, Somers School Camp on the east, Balnarring Beach road on the west and privately owned farmland on the north. It contains the Coolart Homestead, a substantial two-storey brick house, with a third-storey tower and several outbuildings. As well as a well-maintained garden there are several wetlands with a bird hide and a wetland observatory with educational facilities. There are also areas of woodland and farmland. The wetlands are home to a breeding colony of over 1000 ibises, while koalas inhabit the woodlands.
Coolart was originally part of the traditional lands of the Bunurong people, with the word "coolart" deriving from the Bunurong name for nearby Sandy Point. With European settlement of the area Coolart was taken up as a pastoral lease in 1839 by the Meyrick brothers. Subsequently the property went through various farming phases, including cropping and raising sheep and cattle.
The Coolart estate was purchased as a farming property in 1895 by Frederick Sheppard Grimwade, a Melbourne businessman and parliamentarian, with the homestead built immediately thereafter as his family’s country retreat. The property passed through various hands during the early 20th century before it was acquired by Tom Luxton in 1937. Luxton persuaded the state government to declare the property a wildlife sanctuary and began a program of habitat development that included the construction of an artificial lake and other wetlands for waterbirds.
