(5) To avoid doubt, the new licence may be terminated, varied, surrendered or cancelled, and the conditions to which it is subject may be varied, under the Offshore Petroleum and Greenhouse Gas Storage Act 2006.

      

(5A) However, the Joint Authority must not consent under section 270 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 to the surrender, in whole or in part, of the new licence unless the pipeline to which the licence relates has been removed from the surrender area to the satisfaction of NOPSEMA. This has effect despite subparagraph 270(3)(c)(ii) and subsection 270(5) of that Act.

(6) Any dealings that:

(a) related to Pipeline Licence WA-8-PL, granted on 27 April 2001 under Division 4 of Part III of the repealed Petroleum (Submerged Lands) Act 1967; and

(b) were of a kind to which Part 4.6 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 applies; and

(c) were in force immediately before the commencement of this item;

are taken for all purposes also to be in force in relation to the new licence.

      

(7) The Titles Administrator must make an entry of each of the dealings mentioned in subsection (6) on the memorial of the new licence in the Register kept under section 469 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 for the Bayu-Undan pipeline international offshore area.
