Horsnell Gully Conservation Park

[5] The conservation park consists of land in sections 609 and 618 in the cadastral unit of the Hundred of Adelaide.

[6] Land within the conservation park having an area of 1.14 square kilometres (282 acres) first gained protected status as a national pleasure resort during 1947 and prior to 6 August 1947.

[4][7] On 7 March 1963, section 609 was dedicated as part of a wildlife reserve proclaimed under the Crown Lands Act 1929.

[4] The entirety of the conservation park is now leased from the government on a monthly basis for industrial purposes by the neighbouring White Rock Quarry, owned by the German-based multinational company, Heidelberg Cement Group.

10 acres of conservation park land have been cleared and used for stockpiling and dumping of old machinery and vehicles.
