The Minister can declare a part of a reserve to be a prohibited area if the Minister considers that it is necessary for the protection of human life or the conservation of native plants or animals. This must be done by notice published in the Government Gazette and the notice must give the grounds for the decision. A person who enters a prohibited area without a permit issued by the Minister is liable for a fine of up to $1 000 [see National Parks and Wildlife Act 1972 (SA) s 42].
