The game reserve consists of land in both section 349 within the cadastral unit of the Hundred of Freeling and the "150 link reserve adjacent to section 349". The land first acquired protected area status under the Fauna Conservation Act 1964 as both a fauna conservation reserve and a game reserve on 8 January 1970 and was named as the Tolderol Game Reserve. However, the above proclamation was revoked on 26 February 1970 and the land was then re-proclaimed as a fauna conservation reserve under the Crown Lands Act 1929 and as a game reserve under the Fauna Conservation Act 1964. On 27 April 1972, it was reconstituted as a game reserve under the National Parks and Wildlife Act 1972 without change to its name. As of 2019, it covered an area of 4.28 square kilometres (1.65 sq mi).[5][6][7][8][9][3]
In 1980, the game reserve was described as follows:[10]

Modifications to the samphire areas have been undertaken in recent years to enhance the habitat for waterfowl. Shooting of duck is allowed during open season.
