Mediation vs arbitration: what’s the key difference?
Mediation is a confidential, without-prejudice negotiation led by an independent mediator. The mediator does not decide the outcome; the parties do.
Arbitration is a private determination by a qualified arbitrator who considers evidence and submissions and then makes an award that is generally binding and enforceable.
Important: Laws, procedure and enforceability differ across Australian states and territories and by dispute type. This page provides general information only and is not legal advice.
Quick comparison: mediation vs arbitration Australia
| Factor | Mediation | Arbitration |
|---|---|---|
| Decision-maker | Parties (with mediator facilitating) | Arbitrator decides |
| Outcome | Settlement agreement or deed (consent-based) | Arbitration award (binding, private) |
| Typical cost | Often $2,000–$6,000 per day mediator fees + legal costs | Often $5,000–$25,000+ per day arbitrator/venue + legal costs |
| Speed | Days to a few weeks to schedule; 1 day to resolve common matters | Weeks to months (procedural steps, evidence, hearing) |
| Control | High party control over process and terms | Lower party control; arbitrator directs procedure and decides |
| Confidentiality | Generally confidential and without prejudice | Private and confidential by agreement/rules |
| Enforceability | Enforceable as a contract/consent order | Award enforceable under Commercial Arbitration Acts / Family Law Act |
| Use cases | Ongoing relationships, flexible compromises | Technical disputes, need for final binding decision |
How to compare the options
| Factor | Why it matters |
|---|---|
| Control | Mediation preserves control and creativity. Arbitration trades control for certainty of a decision. |
| Cost | A lower upfront cost can be expensive if it fails to resolve the dispute or protect legal position. |
| Speed | Urgent disputes may not suit longer procedures; conversely, rushed bargains can underperform. |
| Enforceability | Mediation depends on a settlement being documented. Arbitration produces an enforceable award. |
| Evidence needs | Complex factual or expert issues may benefit from arbitration’s structured evidence handling. |
| Relationship impact | Mediation can reduce conflict; arbitration is more adversarial but private compared to court. |
When to choose each option
Choose mediation if
- You want a faster, lower-cost pathway with flexibility.
- Keeping a commercial or family relationship matters.
- There’s scope to trade outcomes beyond strict legal rights.
- You need confidentiality and a without-prejudice setting.
- You can live with the possibility of “no deal”.
Choose arbitration if
- You need a binding decision outside the courts.
- Your dispute is technical or evidence-heavy.
- A contract requires arbitration (dispute resolution clause).
- Speed and privacy over litigation are priorities.
- You want cross-border enforceability (in international matters).
Costs: mediation vs arbitration in Australia
Actual costs vary by dispute type, neutral’s seniority, venue and how prepared parties are. Typical ranges:
- Mediation: mediator fees commonly $2,000–$6,000 per day (plus room hire and each side’s legal fees). Some community or court-affiliated mediations may be lower or means-tested.
- Arbitration: arbitrator fees often $5,000–$25,000+ per day for hearing time and directions, with additional fees for reading, award writing, and any room/registry fees. Each side also pays its own lawyers and experts.
Who pays? Parties usually share neutral and venue costs equally unless agreed otherwise or an award directs cost allocation. In arbitration, costs can follow the event unless the rules or agreement say different.
Process overview
Mediation steps
- Agreement to mediate and appoint a mediator.
- Exchange brief position papers and key documents.
- Confidential sessions (joint and private) guided by the mediator.
- Negotiation of terms and heads of agreement or deed.

- Preliminary conference; timetable for pleadings and evidence.
- Disclosure, expert reports and procedural rulings.

Enforceability and Australian legal framework
- Mediation outcomes: Documented as a settlement deed or terms of consent. These are enforceable as contracts, and in some matters can be filed as consent orders.
- Commercial arbitration (domestic): Governed by each state/territory Commercial Arbitration Act (uniform model law). Awards are binding and enforceable through the relevant court.
- Family law arbitration: Available for property and financial matters under the Family Law Act 1975 (Cth). Registered awards can have effect similar to court orders.
- International arbitration: The International Arbitration Act 1974 (Cth) facilitates recognition and enforcement of foreign awards (New York Convention).
Common Australian use cases

Contract clauses: step clauses and arbitration agreements
Australian contracts often include a step clause: negotiate → mediate → arbitrate/litigate. If your agreement mandates mediation or arbitration:
- Check the administering rules (e.g. Resolution Institute, ACICA, IAMA-legacy).
- Confirm seat/place of arbitration, governing law, and language.
- Review appointment method for the mediator/arbitrator and any time limits.
- Assess cost-sharing and confidentiality provisions.
FAQs: mediation vs arbitration Australia
Is mediation or arbitration better in Australia?
Neither is universally “better”. Mediation suits parties who want control, speed and confidentiality with scope to compromise. Arbitration suits parties who need a private, binding decision by a specialist where a negotiated outcome is unlikely or a contract mandates arbitration.
Is arbitration legally binding in Australia?
Yes. Domestic commercial arbitration awards are enforceable under state and territory Commercial Arbitration Acts. Family law arbitration awards can be registered and have similar effect to court orders. International awards can be recognised under the International Arbitration Act 1974 (Cth).
How much does mediation cost in Australia?
Many mediations run at $2,000–$6,000 per day for mediator fees, plus each party’s legal costs and venue. Shorter or community mediations may be less; complex multi‑party mediations may cost more.
How long does arbitration take?
Simple arbitrations may conclude in a few months; complex matters with expert evidence can take 6–12 months or more. Timelines depend on the rules, arbitrator’s directions, and party cooperation.
Can I be forced to mediate or arbitrate?
You can be required to mediate or arbitrate if your contract mandates it or a court orders mediation. Arbitration generally requires agreement (often via a contract clause). Courts frequently encourage or order mediation before trial.
