When a commercial dispute breaks out — a supplier refuses to pay, a contractor walks off a project, a business partner disputes what was agreed — most people assume the only path forward is a court. In Australia, that's rarely true. A large and growing proportion of commercial contracts include an arbitration clause, and when those disputes escalate, the decision-maker stepping in is called an arbitrator.
This article explains what an arbitrator is, how the arbitration process works under Australian law, what a well-drafted arbitration clause needs, and where the process can go wrong. We'll cover:
- The legal definition of an arbitrator and what they can and can't decide
- How domestic and international arbitration are treated differently under Australian law
- The six stages of a typical commercial arbitration
- Common drafting traps in arbitration clauses
- When to get legal help
What is an arbitrator
An arbitrator is an independent decision-maker appointed by the parties to a dispute — or by an appointing authority if the parties can't agree — to resolve a commercial disagreement outside the court system. Their decision is called an award, and it is legally binding.
Arbitrators are typically senior lawyers, retired judges, or experienced industry specialists. They are selected for their expertise in the relevant area (construction, technology, financial services, and so on) and are required to act impartially and in accordance with the rules of natural justice.
The key distinction from other forms of dispute resolution is that the arbitrator decides. This is what separates arbitration from mediation, where a neutral facilitator helps parties reach their own agreement. A mediator cannot impose an outcome. An arbitrator can — and does.
Arbitration also differs from litigation in that it is private. Court proceedings are generally open to the public and on the public record. An arbitration is confidential to the parties, which is often important when the dispute involves commercially sensitive information, trade secrets, or reputational risk.
The legal framework in Australia
Australian arbitration law distinguishes between domestic and international disputes, and each is governed by different legislation.
Domestic commercial arbitration is governed by harmonised State and Territory legislation — the Commercial Arbitration Acts. Each Australian jurisdiction has enacted substantially identical legislation: the Commercial Arbitration Act 2010 (NSW) is the most referenced, with equivalent Acts in Victoria, Queensland, South Australia, Western Australia, the ACT, and the Northern Territory. These Acts are modelled on the UNCITRAL Model Law on International Commercial Arbitration (as amended in 2006), ensuring consistency across borders.
International commercial arbitration — where one party is based overseas or the commercial relationship has a foreign element — is governed by the International Arbitration Act 1974 (Cth). That Act gives force of law in Australia to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards 1958, which means awards made in any of the 170-plus signatory countries can be enforced in Australian courts. Under s 8 of the Act, a foreign award may be enforced in the Federal Court of Australia as if it were a judgment of that court.
Regardless of which legislative framework applies, the core principle is the same: an arbitrator's award is designed to be final and enforceable, with very limited grounds for challenge.
How does the arbitration process work
Every arbitration follows a recognisable sequence, though the details — timelines, evidence rules, hearing format — are highly flexible.
Step 1: Agreement to arbitrate
Arbitration only happens if the parties have agreed to it. This agreement usually sits inside a commercial contract, in a clause labelled "dispute resolution" or "arbitration". If a dispute arises and there's no pre-existing clause, the parties can sign a separate arbitration agreement after the fact, but that requires both sides to cooperate at a moment of conflict — which is often difficult.
Step 2: Nominating the seat and procedural rules
The seat of the arbitration is its legal home — an Australian State or Territory whose procedural law will govern the process. This matters because the seat determines which court can supervise the arbitration if something goes wrong, and which Commercial Arbitration Act applies.
Most arbitration clauses in commercial contracts also adopt an institutional set of rules rather than starting from scratch. In Australia, the Australian Centre for International Commercial Arbitration (ACICA) provides widely used rules. ACICA also acts as the default appointing authority under the International Arbitration Act 1974 (Cth) when parties can't agree on an arbitrator. Adopting institutional rules avoids lengthy procedural negotiations once a dispute has already started.
Step 3: Appointing the arbitrator
Most commercial disputes use a sole arbitrator. For larger or more complex matters, a panel of three may be appointed. The method of appointment should be set out in the arbitration clause: typically, the parties attempt to agree on a name, and if they can't agree within a fixed period, an appointing authority (such as ACICA) makes the appointment.
Step 4: Case management and evidence exchange
Once the arbitrator is in place, a preliminary conference is held to set the timetable. The parties exchange pleadings, documents, witness statements, and any expert reports. Hearings can be conducted in person, online, or on a documents-only basis — the last option being faster and cheaper for many SME disputes.
Step 5: The award
After submissions and any hearing, the arbitrator issues a written award. It is binding. Courts can enforce it. The grounds to challenge an award are narrow: under s 34 of the Commercial Arbitration Act 2010 (NSW) (and equivalent provisions elsewhere), a party may apply to set aside an award only on limited procedural grounds — such as incapacity of a party, lack of proper notice, the dispute falling outside the scope of the submission, or a serious breach of natural justice. An appeal on the merits of the decision is only available if the parties have expressly agreed to permit it, under s 34A.
Step 6: Settlement remains possible at any time
Commercial disputes frequently resolve before a final award is issued. If the parties reach agreement during the arbitration, they can record the settlement in a deed of release or ask the arbitrator to issue a consent award — a procedural step that preserves the confidentiality and finality of the process.
Common misconceptions about arbitration
"Arbitration is always faster and cheaper than court." Not necessarily. An ad hoc arbitration with no agreed rules, a three-member panel, and contested evidence can take just as long and cost just as much as litigation. Speed and cost depend on the quality of the arbitration clause and the willingness of both parties to proceed efficiently.
"Any dispute can go to arbitration." Courts retain jurisdiction over certain matters that cannot be arbitrated — including some statutory rights and insolvency proceedings. An arbitration clause does not entirely replace the court system; it displaces it for the categories of dispute it covers.
"The arbitrator's decision can easily be appealed." In most domestic arbitrations, an appeal on the merits requires the parties to have expressly opted in. Without that opt-in, the only recourse is a setting-aside application on narrow procedural grounds. This finality is intentional — it's one of the features that makes arbitration commercially attractive — but it also means a poorly prepared case has limited recovery options.
"Signing an arbitration clause means you can't go to court for urgent relief." A well-drafted clause will expressly preserve the right to seek urgent interim relief from a court (such as an injunction) without that being treated as a waiver of the arbitration agreement.
Drafting an arbitration clause: what to include and what to avoid
An arbitration clause is most useful when it is specific. Vague wording creates procedural disputes at the worst possible time.
A functional clause should address:
- Scope — which disputes are covered (the standard formulation is "arising out of or in connection with this agreement")
- Seat — the State or Territory whose law governs the procedure
- Institutional rules — the rules the arbitration will run under (ACICA or similar)
- Appointment mechanism — how the arbitrator is chosen and which authority appoints if parties can't agree
- Number of arbitrators — sole arbitrator or panel of three
- Hearing format — allowing for virtual or documents-only hearings where appropriate
- Confidentiality — an express obligation on both parties and the arbitrator
- Interim relief carve-out — preserving the right to go to court for urgent orders without waiving arbitration
Common drafting errors include: using mixed wording such as "litigation or arbitration" (which courts have found ambiguous); failing to nominate a seat (which creates a procedural fight before the substantive dispute can be resolved); and drafting an overly narrow scope clause that accidentally excludes the very dispute that ends up arising.
How Artificer Legal can help
Arbitration clauses look simple but interact with the rest of a contract in ways that matter. A clause that works for a standard supply agreement might not work for a joint venture with multiple counterparties, a cross-border licensing deal, or a construction contract where statutory rights are in play.
Artificer Legal assists with:
- Reviewing existing contracts to identify whether arbitration clauses are enforceable and fit for purpose, and whether they interact sensibly with indemnity, limitation of liability, and termination provisions
- Drafting arbitration clauses tailored to the commercial relationship — domestic or international, sole arbitrator or panel, expedited or standard process
- Pre-dispute strategy — helping you map issues, identify evidence, and understand your realistic options before you commit to a process
- Representation — running arbitration proceedings end to end, including case management, submissions, and expert evidence coordination
We focus on commercial clients — businesses, founders, and operators — who need practical, technically sound legal advice without the overhead of a large firm.
What to take away
Arbitration is a private, binding dispute resolution process — not a mediation and not a court proceeding. The decision-maker is an arbitrator: an independent expert who applies the law and issues a final award.
Key points:
- Domestic commercial arbitration in Australia is governed by harmonised State and Territory legislation (the Commercial Arbitration Acts); international disputes fall under the International Arbitration Act 1974 (Cth)
- An arbitrator's award is binding and enforceable in court; grounds to challenge are narrow and procedural
- A well-drafted arbitration clause specifying the seat, institutional rules, and appointment mechanism is what makes the process work when a dispute actually arises
- Arbitration is not automatically cheaper or faster than court — it depends on how the clause is drafted and how the parties conduct the proceedings
- If you're reviewing or negotiating a commercial contract, the dispute resolution clause deserves the same attention as the pricing, indemnities, and termination rights
