Several features of the Act and the scheduled agreements are easy to overlook but have significant practical consequences. First, the “notwithstanding any other Act or law” provisions in sections 3(2), 4(3), 5(3), 5A(3), 6A(3) and 6B(3) are not absolute , they are limited by the specific savings clauses within the Agreement. Clause 33 preserves environmental requirements under any Act, including the Environmental Protection Act 1986 as confirmed by the Fifth Supplementary Agreement. Clause 34 preserves the State’s liability for its own negligence when carrying out work for the Joint Venturers, so the indemnity in favour of the State does not apply if the State is negligent. Clause 47 provides that the Agreement is to be interpreted according to Western Australian law, but the Fifth Supplementary Agreement added a specific submission to the jurisdiction of Western Australian courts for disputes not referred to arbitration. Second, the definition of “associated company” in clause 1 of the principal Agreement requires that the company be incorporated or formed within the United Kingdom, the United States, the Netherlands, Australia, Japan (added by the First Supplementary Agreement) or such other country as the Minister may approve, and that the Joint Venturers hold not less than a 25% interest (or a lesser interest acceptable to the Minister). This is a relatively restrictive definition that could affect assignment rights under clause 26. Third, the force majeure clause (clause 28) is broad but has a critical carve‑out: it does not apply to the Domgas Commitment’s marketing, reporting, reservation and consultation obligations , clause 46A(8) expressly states that clause 28 does not apply to clause 46A(4)(a), (b), (c), (g) and (h). This means that a force majeure event will not excuse the Joint Venturers from actively marketing New Domgas, negotiating in good faith, or preparing annual reports. Fourth, the liability of each Joint Venturer is separate and limited to its equity proportion in the relevant venture (clause 40, as amended by the First Supplementary Agreement). However, for obligations relating to Common Property, liability is shared between the Domgas and LNG Joint Venturers in accordance with approved proposals. A default by one Joint Venturer does not necessarily affect the others, but the Minister may determine the Agreement only as to the venture to which the default relates, leaving the other venture intact. Fifth, the stamp duty exemption in clause 37(1) applies only to instruments executed within nine years of the date of the principal Agreement (27 November 1979). After 27 November 1988, the exemption no longer applies to the Agreement itself, leases, assignments, security documents, insurance policies or gas sales agreements. Later supplementary agreements (for example, the 2014 Fourth Supplementary Agreement and the 2019 Fifth Supplementary Agreement) contain their own stamp duty refund provisions (clause 5 of the Second Supplementary Agreement and clause 5 of the Third Supplementary Agreement), but these are limited to the instruments specifically referred to in those agreements. Sixth, the variation power in clause 27 allows the parties to amend the Agreement by written deed, but any such variation must be laid before both Houses of Parliament within 12 sitting days, and either House may disallow it within 12 sitting days. This means that significant variations (such as the 1982 and 2002 agreements) take effect subject to possible parliamentary disallowance, creating political risk for the Joint Venturers. Seventh, the cessation or determination provisions in clause 31 are harsh: all buildings and improvements become the property of the State without compensation, and the Joint Venturers’ option to remove plant and equipment is subject to the State’s right to purchase in situ at a fair valuation. This creates a substantial risk for lenders financing the project, as their security over fixed plant may be lost upon termination. Eighth, the definition of “Agreement Area” in the Fourth Supplementary Agreement is limited to the specific petroleum titles listed in the Schedule to that agreement and any titles derived from them. It does not automatically include all future titles the Joint Venturers may acquire, meaning that new discoveries outside the listed titles would require further variation or separate arrangements. Ninth, the community development plan and local participation plan under the Fifth Supplementary Agreement (clauses 11A and 11B) impose ongoing reporting and conferral obligations that apply not only to the Joint Venturers but also require them to impose conditions on third‑party contractors. The local participation plan must include detailed procurement practices and communication strategies, and the Joint Venturers must report annually on implementation. Failure to comply could be a material default. Tenth, the water supply cessation clause in the Fifth Supplementary Agreement (new clause 18(5)) terminated the State’s water supply obligations under the Agreement on the Second Variation Date, replacing them with a separate commercial Water Supply Agreement. This is a rare example of a clause that removes a long‑standing State duty, and practitioners should verify that the commercial agreement adequately covers the Joint Venturers’ needs.
