When assessing whether Crown land is 'likely to be needed' for an essential public purpose under s 36(1)(c) of the Aboriginal Land Rights Act 1983 (NSW), the question is whether there is a trajectory towards a requirement at the appropriate government level, not whether the trajectory itself exists at that level. The non-inclusion of claimed land in a national park after the date of claim cannot be treated as relevant where the non-inclusion is attributable to the existence of the undetermined land claim itself. The majority and dissent disagreed on whether the trial judge's reference to 'appropriate government level' constituted legal error or a permissible factual evaluation.
