From Parks Victoria website:
Lysterfield Lake was once a storage reservoir for the Mornington Peninsula from 1936, until it was no longer required for water supply due to the opening of Cardinia Reservoir in 1975. During the period up to 1965, farmland adjacent to the lake was acquired by the State Rivers and Water Supply Commission to protect the quality of the water. As a Bicentennial project in the early 1980's facilities were developed in the park to cater for a variety of recreation activities. The park was opened to the public in November 1986.
Lysterfield Park provides a diverse range of habitats and as such is a valuable wildlife refuge. The list of bird species recorded is about 140. Of these, 37 are waterbirds and include common species such as Eurasian Coots and Eastern Swamphens to the uncommon visitors such as Japanese Snipe and Red-necked Avocet. Amongst the fauna, Eastern Grey Kangaroos and Black Wallabies are readily seen whilst Koalas, antechinus and echidnas are much harder to find. At night the park comes alive with Brushtail and Ringtail Possums, Sugar Gliders and various species of bats and owls.
The park entrance is from Horswood Road off the Belgrave-Hallam Road (Melway ref: 108 D2). Lysterfield Park is open every day of the year. Opening and closing times vary according to daylight savings. For up to date information on park closing times call the Parks Victoria Information Centre on 13 1963.
