1978年签署的《兰杰协定》是澳大利亚历史上第一个有关在土著土地上开采铀矿的协定。该协定是联邦政府以及矿业利益集团对北领地区的土著施加压力的结果，反映了联邦政府对铀的开发利用的立场与政策日渐明朗以及矿业利益集团在“国家利益”的名目下对土著所在地区的矿产进行“合法”开发的前景，同时折射了土著土地所有权的脆弱性与模糊性。但应予肯定的是，针对铀矿开发可能引发诸如环境破坏等方面的调查及其应对之策为日后处理此类问题树立了先例。

The Ranger Agreement signed in 1978 is the first agreement about the development of uranium in the aboriginal land in the history of Australia. As the result of the pressure that aboriginals received from the Commonwealth government and the mining interest groups, the Agreement reflects the increasing clearness of the standpoint and policy of the Commonwealth government on developing uranium, and the ambition of the mining interest groups to “lawfully” develop mines in aboriginal owned land under the name of “national interest”. Meanwhile, it mirrors the fragility and fuzziness of aboriginal land ownership. However, it shall be admitted that it has set an example in carrying out a comprehensive investigation on environmental disruption and other problems caused by the development of uranium as well as their countermeasures.
