Strategic Dispute Support

Disputes are an inherent part of project delivery. As long as clients engage contractors to perform complex work, differences will inevitably arise — whether over scope, cost, time, quality, or interpretation of obligations. At HJA Dispute Services, we understand that disputes don't just involve legal issues — they are often commercial, technical, and involve complex considerations including personalities and broader business relationships. Our role is to help clients manage these challenges with clarity and confidence, minimising disruption and guiding parties toward effective resolution.

Our experienced team has worked on some of the most high-profile and complex projects across Australia. For over two and a half decades, HJA and their dispute experts have supported their clients in more than 500 disputes worth in excess of AUD$5 billion. Our team have also assisted in the preparation, defence and determination of over 250 adjudications in both Australia and the UK.

At our core, we offer commercial outcomes for our clients, advising them through dispute resolution, negotiation or prosecution to consider the outcomes where conflict has arisen.

Major Claims Management

At HJA Dispute Services, we have worked on major claims across some of Australia’s most complex infrastructure and resources projects. Our team has a proven track record in leading and supporting high-stakes claims involving multiple stakeholders, legal teams, and technical experts. Whether working to avoid litigation, preparing expert submissions, or managing post-dispute processes, we bring clarity, structure, and commercial focus to every engagement.
