What Evidence Do You Need to Win at QCAT in Queensland

# What Evidence Do You Need to Win at QCAT in Queensland

QCAT does not care about your story. It cares about your evidence.

You can have a completely justified claim — unpaid invoice, defective goods, rental bond wrongly withheld — but if you walk into the hearing room without the right documents, organised properly, you lose. The Queensland Civil and Administrative Tribunal operates on evidence, not emotion.

What counts as evidence at QCAT

QCAT accepts several types of evidence. Not all of it carries the same weight.

Documentary evidence — contracts, invoices, receipts, emails, text messages, letters, bank statements, photos, videos, inspection reports, expert reports. This is the backbone of most QCAT cases.

Witness statements — written statements from people who saw or heard something relevant. Must be signed and dated. The witness may need to attend the hearing to be cross-examined.

Physical evidence — defective products, damaged goods, samples. Bring the actual item if practical, or high-quality photos if not.

Expert evidence — reports from qualified professionals (building inspectors, mechanics, accountants, valuers). QCAT typically gives expert evidence significant weight if the expert is properly qualified and independent.

Oral evidence — what you and your witnesses say at the hearing. Less reliable than documents. QCAT prefers written proof.

The golden rule: if it is not in writing, it did not happen. Verbal agreements, phone conversations, and undocumented promises are almost impossible to prove.

Documents you need for common QCAT disputes

Different dispute types require different evidence. Here is what QCAT typically expects for the most common claims.

Unpaid invoices and debt recovery

• Original contract or service agreement
• Tax invoice showing the amount owed, date due, and payment terms
• Proof of delivery or completion (delivery dockets, completion certificates, photos of finished work)
• Correspondence chasing payment (emails, letters, text messages)
• Bank statements showing no payment received
• Letter of demand sent to the debtor
• Any partial payments received (bank statements, receipts)

Defective goods or services

• Receipt or proof of purchase
• Original contract or quote
• Photos or videos showing the defect
• Expert report (if the defect is technical — building, mechanical, electrical)
• Correspondence with the seller or service provider
• Repair quotes or invoices to fix the problem
• Evidence of attempts to resolve the issue (emails, complaint records)

Rental bond disputes

• Tenancy agreement
• Entry condition report signed at the start of the tenancy
• Exit condition report
• Photos of the property at move-in and move-out
• Receipts for any repairs or cleaning done by the tenant
• Correspondence with the landlord or agent about the bond
• RTA Form 4 (bond lodgement receipt)
• Any notices issued during the tenancy

Consumer claims

• Receipt or proof of purchase
• Product warranty or guarantee documents
• Photos or videos of the fault
• Correspondence with the seller

• Proof the failure was not caused by misuse

Building and construction disputes

• Plans and specifications
• Payment schedule and invoices
• Photos of defective or incomplete work
• Expert building inspection report
• Correspondence with the builder
• Any variation orders or change requests

How to organise your evidence for QCAT

QCAT members hear dozens of cases. They do not have time to hunt through a pile of loose papers.

Create a hearing bundle — a single folder or binder containing every document you intend to rely on, arranged chronologically or by topic. Number every page. Include a table of contents at the front.

Make copies — you need three copies of everything. One for you, one for the other party, one for the QCAT member.

Label everything clearly — use tabs or dividers. Mark each document with a short description and the date. If you are submitting 40 pages of emails, highlight the relevant parts.

Put it in order — chronological order works for most disputes. Start with the contract or agreement, then move forward in time. For complex cases, organise by issue (liability, quantum, mitigation).

Include a cover sheet — one-page summary listing your name, the QCAT reference number, the hearing date, and a brief description of each document in the bundle.

File it early — QCAT rules typically require you to file and serve your evidence at least 7 days before the hearing (sometimes longer, depending on the dispute type).

Common evidence mistakes that lose QCAT cases

No written contract — you claim there was an agreement. The other party denies it. Without a written contract, email trail, or signed quote, QCAT cannot enforce something that may not exist.

Hearsay evidence — “My friend told me the builder did a bad job.” That is hearsay. Your friend needs to provide a signed witness statement or attend the hearing.

Undated or unsigned documents — invoices without dates, contracts without signatures, emails with the date cut off. QCAT cannot rely on documents that lack basic authentication.

No proof of service — you sent a letter of demand but cannot prove the other party received it. Always use registered post or email with read receipts.

Photos without context — a photo of a cracked wall means nothing without a date, location, and explanation of when the damage occurred.

Missing financial records — you claim $8,000 in lost income but provide no tax returns, bank statements, or invoices to support it. QCAT will not award damages based on guesswork.

Failing to mitigate loss — you claim ongoing rental loss because the tenant left early, but you made no effort to re-let the property. QCAT expects you to minimise your loss.

What happens if you do not have enough evidence

QCAT operates on the balance of probabilities. You do not need to prove your case beyond reasonable doubt (that is criminal law). You just need to show it is more likely than not that your version is correct.

But if your evidence is weak — no contract, no receipts, no correspondence — the other party only needs to deny your claim and QCAT has nothing to decide on. The application gets dismissed.

If you realise mid-case that your evidence is insufficient, you can apply to adjourn the hearing to gather more. QCAT may grant it, but only if you have a good reason and the delay is not your fault.

What to do if the other party has better evidence

Sometimes the other side has documents you do not. A signed contract you never received. An email you deleted. A receipt you lost.

You can apply for discovery — a formal process where QCAT orders the other party to produce documents. This is more common in higher-value disputes. For minor tribunal matters, QCAT expects both parties to exchange evidence voluntarily before the hearing.

If the other party refuses to hand over critical documents, raise it at the hearing. QCAT can draw an adverse inference — meaning it assumes the missing document would have supported your case, not theirs.

But do not rely on this. The best evidence is the evidence you control. Keep records, save emails, photograph everything, and never throw away a receipt until the dispute is resolved.

Frequently Asked Questions

Can I submit evidence on the day of the QCAT hearing?

QCAT typically requires all evidence filed and served at least 7 days before the hearing. You can apply to submit late evidence, but the member may refuse it or adjourn the hearing, which delays your case and may result in cost orders against you.

Do I need a lawyer to prepare evidence for QCAT?

No. QCAT is designed for self-represented parties. You do not need a lawyer, but you do need to organise your evidence properly. ClaimDone can help you prepare a formatted hearing bundle and tribunal application without the cost of a solicitor.

What if I do not have a written contract?

You can still bring a claim, but it is harder to prove. Gather any emails, text messages, quotes, invoices, or payment records that show an agreement existed. QCAT can infer a contract from conduct, but written proof is always stronger.

Can I use text messages and WhatsApp as evidence at QCAT?

Yes. Print them out or save them as PDFs with the date, time, and sender clearly visible. Screenshots are acceptable, but make sure they show the full conversation thread and are not cropped or edited.

How do I prove someone received my letter of demand?

Use registered post with tracking, or email with a read receipt. If you hand-delivered it, get a signed acknowledgment. Without proof of service, QCAT may not accept that the other party was properly notified.
