The Nature Conservation Act 1992 is an act of the Parliament of Queensland that provides for the legislative protection of Queensland's threatened biota. As originally published, it provided for biota to be declared presumed extinct, endangered, vulnerable, rare or common. In 2004 the act was amended to more closely align with the IUCN Red List categories: presumed extinct was changed to extinct in the wild and common was changed to least concern. Near threatened was introduced as an eventual replacement for rare, but the latter was to be phased out over time rather than immediately abandoned.
