Mary Carroll Park

Mary Carroll Park is a large public wetland park in Gosnells, about 20 km southeast of Perth, Western Australia. Centred on Mary Carroll Lake, the park combines rehabilitated wetlands, open grasslands and bushland. It is notable for its birdlife, walking trails and family recreation facilities. Managed by the City of Gosnells, it serves as a key community open space and urban nature reserve for walking, picnicking and nature observation.

Visitors can expect a flat, open parkland centred on Mary Carroll Lake and surrounding wetlands with fringing paperbarks and reeds. Paved and unpaved walking paths circle the lake and extend through grassed areas and bushland. Facilities include a playground, barbecue and picnic areas, seating, toilets and car parking. The setting is popular for walking, jogging, birdwatching and family picnics in a quiet suburban environment.

The park is named after Mary Carroll, wife of early settler John Carroll who held land in the Gosnells area. The lake and wetlands occupy a former clay pit and later landfill site that was rehabilitated from the 1980s by the City of Gosnells into a conservation wetland and public park.
