WA Security of Payments law passed

22 June 2021

The Building and Construction (Security of Payments) Bill 2021 was passed by the WA Parliament on 22 June 2021, and brings WA into line with other national security of payments legislation for the building and construction sector. Importantly, it:

(a) strengthens contractor payment protections by enshrining payment rights, capping payment times and recognising contractors’ rights to claim a lien over unfixed plant and equipment where progress claims are unpaid;

(b) expands the application of the law and further narrows the mining exemption which will be mean construction work undertaken in relation to resources projects will likely be captured;

(c) broadens voidable contract provisions by extending the prohibition of ‘pay when paid’ provisions to include provisions dependent upon the operation of another contract, and enabling a decision-maker to deem void any onerous or unreasonable time-bar provisions (e.g. requiring certain notice or steps to be taken to preserve contractual claims for delays, variations and latent conditions, etc.);

(d) deems that retention monies are held on trust and are to be managed as trust monies in trust accounts to insulate them from a head contractor’s insolvency;

(e) requires notice to be given before calling on a performance security and enables contractors to exchange performance bonds for retention monies; and

(f) enables the Building Services Board to better manage ‘phoenix’ activity by builders with a history of insolvency by declaring them ‘excluded’.

Companies engaged in or procuring construction work should review their contracts to ensure they accommodate the new law and do not contain potentially voidable provisions, and ensure their processes and procedures are compliant before the new law before it comes into effect.

High Court confirms limited scope to overturn adjudicator’s findings; finds certain retention clauses prohibited

17 February 2018

The High Court of Australia has found that an adjudicator’s award under security of payments legislation in New South Wales and South Australia cannot be challenged unless an adjudicator acts beyond power.

In two decisions handed down in February 2018, Maxcon Constructions Pty Ltd v Vadasz [2018] HCA 5 and Probuild Constructions (Aust) Pty Ltd v Shade Systems Pty Ltd [2018] HCA 4, the court held that:

“the [court]… may grant relief (whether in the nature of certiorari or otherwise) for jurisdictional error by an adjudicator appointed under the Security of Payment Act; but the provisions of the Security of Payment Act, like the provisions of the New South Wales Act, oust the Supreme Court’s jurisdiction to make an order in the nature of certiorari to quash an adjudicator’s determination for error of law on the face of the record that is not a jurisdictional error.” Maxcon at [5]. The court emphasised that an adjudication did not finally determine the rights of the parties under a construction contract and that it was open to seek relief by commencing separate court proceedings, rather than seeking to challenge the adjudication itself.

The effect of these decisions is that even when an adjudicator misinterprets the law or a construction contract, the court cannot quash the decision unless it can be shown that the adjudicator has acted beyond their jurisdiction or beyond power. This is consistent with findings of the WA Supreme Court in O’Donnell Griffith Pty Ltd v John Holland Pty Ltd [2009] WASC 19 concerning adjudicators appointed under the WA Construction Contracts Act 2004. It highlights the importance of choosing adjudicators wisely.

Additionally, the court in Maxcon found that a retention provision, enabling a head contractor to deduct monies from an amount owing to a subcontractor, pending the release of a certificate of occupancy in respect of the works, which in turn would depend on completion being achieved under the head contract with the owner, constituted a ‘pay when paid’ provision, and was thus ineffective. The court found that a ‘pay when paid’ provision under the South Australian legislation:

“asks whether, on its proper construction, the provision “makes the liability to pay money owing, or the due date for payment of money owing, contingent or dependent on the operation of another contract”. Here,the retention provisions did just that: they made the due dates for payment contingent or dependent on “CFO”. And for “CFO” to be achieved, there had to
be issued a certificate of occupancy and “any other Approval(s) required under Building Legislation which [were] required to enable the Works lawfully to be used for their respective purposes in accordance with [Maxcon’s] Project Requirements”. Those Project Requirements were to be ascertained from the head contract. “CFO” required satisfactory completion of the head contract before the dates for the release of the retention sum could be calculated, let alone for the retention sum to be released. Accordingly, there was no error of law on the part of the adjudicator.” 

In view of the above, contracts containing retention provisions ought to be reviewed to ascertain whether they may be construed as ‘pay when paid’ provisions, and thus be inoperative under the relevant legislation in your State.

In WA, the comparable provision (section 9 of the Construction Contracts Act 2004) prohibits provisions that render payment to one person contingent on payment being received from another. In that way, it does not refer more generally to the ‘operation of another contract’ as was the case in Maxcon and may be distinguishable to that extent, but care should still be taken that the drafting of any retention provisions do not ‘indirectly’ rely on payment from another party.

Native Title Reforms: Options Paper

29 November 2017

An options paper has been released for public comment on broad ranging reforms to the Native Title Act 1993 (Cth), which can be viewed here.

The options for reform relate to:

  • validating past section 31 native title agreements and changing the requirements concerning applicants being party to and executing these agreements
  • changing the manner in which applicants are authorised and clarifying their functions and duties
  • establishing alternative native title agreement making processes that do not require broader group consultation
  • enabling registered Indigenous Land Use Agreements (ILUAs) to have minor changes made that do not require re-authorisation and registration
  • making minor changes to native title processes to streamline decision-making and future acts (e.g. removing the State as a compulsory party to agreements, removing the requirement for prescribed bodies corporate (PBCs) to consult with land councils, removing compensation requirements from ILUAs)
  • enabling native title parties to choose decision-making processes rather than being compelled to use traditional decision-making
  • securing regulatory oversight of PBCs by ORIC for compliance with PBC regulations and the management and use of native title compensation monies, including through external trusts
  • establishing dispute resolution processes through the National Native Title Tribunal and limiting the hearing of matters under the Corporations (Aboriginal and Torres Strait Islander) Act 2006 (Cth) to the Federal Court of Australia.

Submissions on the options paper are due on 25 January 2018 by emailing them to

Public consultations will also occur through targeted discussions with native title stakeholders and the engagement of an expert advisory panel to formulate amendment proposals.

An exposure draft amendment bill will be released for comment in around March 2018.

If you would like assistance with preparing a submission or advice on the implications of the reforms for your organisation, please contact Maria Lamattina.
