Northern Territory Consolidated Regulations Northern Territory Consolidated Regulations6.14. Recovery of vacant land
(1) In a proceeding for the recovery of land, the Court may:
(a) if it is satisfied that no person appears to be in possession of the land and that service of originating process cannot be otherwise effected on a defendant without undue delay or expense, authorize service on the defendant to be effected by affixing a copy of the originating process to a conspicuous part of the land; or
(b) if it is satisfied that no person appears to be in possession of the land and that service could not otherwise have been effected on a defendant without undue delay or expense, order that service already effected by affixing a copy of the originating process to a conspicuous part of the land shall be taken to be good service on the defendant.
(2) This rule has effect notwithstanding that the defendant is out of the Territory at the time of affixing the copy of the originating process.
