Attorney-General v Helicopter-Tjungarrayi (Ngurra Kayanta & Ngurra Kayanta #2)

The case between the Attorney-General for the Commonwealth of Australia and Helicopter-Tjungarrayi (Ngurra Kayanta & Ngurra Kayanta #2) involved a dispute regarding the interpretation of certain sections of the Native Title Act 1993 (Cth). The core of the dispute was whether petroleum exploration permits granted under state legislation constituted "mining leases" within the meaning of section 47B of the NTA, and if such permits meant that part of the claim area was covered by a permission or authority under which land was to be used for a particular purpose, as outlined in section 47B(1)(b)(ii) of the NTA. This matter was decided by the Federal Court of Australia.

The legal issues before the court were twofold: firstly, whether the petroleum exploration permits granted under state legislation qualified as "mining leases" for the purposes of section 47B(1)(b)(i) of the NTA; and secondly, whether these exploration permits indicated that part of the claim area was covered by a permission or authority under which land was to be used for a particular purpose, as specified in section 47B(1)(b)(ii) of the NTA. The court was required to interpret these sections in light of the nature and purpose of the land use under the exploration permits, and the extent of the land to be used.

The court held that the exploration permits were indeed "mining leases" for the purposes of section 47B(1)(b)(i) of the NTA, which led to the exclusion of section 47B from operation. However, the court determined that the exploration permits did not satisfy the conditions set out in section 47B(1)(b)(ii) of the NTA. Consequently, the appeal by the state was allowed, while the appeal by the Commonwealth was dismissed. The court's judgment was reflected in the orders which amended the attachment to the previous orders dated 15 August 2017.
