In 1866, when John Crozier bought the property, it was fully planted with irrigated oranges in the front orchard, vineyards nearby and accompanying pastures for sheep, cattle and horses. The house had a cellar that held 50 000 gallons ( 180 000 litres ) of wine.
The property was sold to Thomas Currie Tait in 1906 but in 1915 the property was split by the new Adelaide Willunga rail line. Many of the large gums were used as sleepers for the line.
In 1951 Oaklands Homestead was sold to the Crown.
When a number of Oaklands Estate gum-trees were being uprooted in 1952, a local group formed the Oaklands Estate Residents' Association with the aim of saving some of the trees. Members volunteered to plant and care for 1 200 native street trees including a shrubbery around Marion Railway Station. They also helped to initiate the gazetting of a sizeable portion of land adjacent to the Sturt River for recreational use. The City of Marion has taken responsibility for that area.
By 1964 flooding had become a constant problem and vegetation was cleared in preparation for the concrete lining of the river which began in 1968.
The Homestead had been leased to Horace Pethick but when he left it remained vacant and was heavily vandalised. The building was finally destroyed by the South Australian Government in 1967 in anticipation of a freeway development that never happened. It was bulldozed into its own cellar and is buried beneath the carpark.
The Road Safety School was opened in the front section of the of the property in 1972. In 2011 the Driving School was ceded by the Government of South Australia and has been developed as a wetlands .
Further development of the area has progressed with an activity Plaza being created on the northern edge. This comprises a skateboard park and a basketball zone at the moment and is presently being expanded with more public facilities. A large rotunda is being constructed and a larger car park will give greater access to this section.
To the south the reserve will be re-developed in 2018 and will include increased play stations for children.
