How to request release of a commercial lease deposit after a disputed fit‑out in Australia

If your landlord is withholding a commercial lease security deposit or refusing to release an original bank guarantee because of a disputed fit‑out, the fastest, most realistic route is: confirm what the lease and local law say about the deposit; gather clear fit‑out evidence (photos, invoices, handover notes); make a written demand and ask for an itemised deduction list; then apply to your state Small Business Commissioner's mediation service before considering a tribunal. The specific holding rules and next steps vary by state, so follow the state guidance for your premises' location.

That short answer explains the practical sequence. Below I explain why each step matters, what evidence convinces mediators or a tribunal, how Victoria, NSW and Queensland differ, and when a tribunal or legal advice becomes necessary.

Step 1 — Check the lease and identify the security type

Your lease is central. It will usually say whether the security is a cash bond, a bank guarantee, or another form of security and set out any conditions for deductions or set‑off for damage, reinstatement or unfinished fit‑out works. If the lease requires the landlord to hold a cash bond in a particular way or limits deductions, those clauses will shape your arguments in mediation or at a tribunal.

If the tenancy is a retail lease in NSW there are options to lodge retail bonds; the NSW Government explains retail rental bond arrangements and where to find further detail on the bond scheme on its retail rental bonds page, which is the right starting point for tenants in NSW: Retail rental bonds | NSW Government. For general commercial lease guidance in NSW see Service NSW's referral page on retail and commercial leases: Learn about retail and commercial leases | Service NSW.

Why this matters: if the lease gives the landlord a contractual right to retain funds for certain defects or unfinished items, your argument will focus on whether those conditions were met and whether the landlord proved the loss.

Step 2 — Gather the documentary evidence that mediators and tribunals rely on

A mediator or tribunal will focus on the facts you can prove: dates, photos showing the fit‑out state at handover and at lease end, contractor invoices and payment receipts, handover checklists, written instructions or approvals from the landlord, and any correspondence where you asked the landlord to inspect or accept work.

Prepare a tight bundle that shows:

• what the lease required you to do at the end of the lease (removal obligations, repairs, reinstatement);
• the condition of the premises at handover and on vacating (timestamped photos help);
• invoices and paid receipts for the fit‑out and any repair work; and
• written correspondence that records requests or disputes with dates.

The Queensland Small Business Commissioner’s fact sheet on repairs and maintenance explains the kind of documentary detail that helps in a lease dispute: Repairs and maintenance - Queensland Small Business Commissioner.

Why this matters: mediators and tribunals will not decide on general fairness— they decide what the lease and the evidence show. Solid documentary proof narrows the dispute and increases the chance of a negotiated return or an order in your favour.

Step 3 — Make a clear written request and ask for itemised deductions

Send a concise written demand (email plus a registered or tracked delivery if you need proof) that: states the amount or security you want released, cites the lease clause or lack of legal basis for withholding, attaches your key evidence, and asks the landlord to provide an itemised list of any deductions with invoices or quotes within a stated but reasonable timeframe.

The Queensland Small Business Commissioner advises tenants to seek an itemised explanation and to attempt negotiation before escalating: Leasing disputes - Queensland Small Business Commissioner.

Why this matters: an itemised response lets you see whether the landlord’s claimed deductions are genuine costs supported by invoices, or a position you can narrow or contest in mediation.

Step 4 — Use the Small Business Commissioner / mediation service early

NSW, Victoria and Queensland each offer small business mediation services that handle lease and bond disputes. These services are a low‑cost, faster alternative to tribunals and often a required step before you can apply to certain tribunals for retail lease disputes.

• For NSW tenancy and bond mediation, start with the NSW Small Business Commissioner: I have a question or need information | NSW Small Business Commissioner.
• In Victoria the Victorian Small Business Commission handles bond disputes and can issue a certificate to apply to VCAT in some retail lease matters; VSBC explains bonds and returning security: Security deposits | Victorian Small Business Commission. The VSBC also sets out steps for ending a retail lease early: Ending a retail lease early | Victorian Small Business Commission.
• In Queensland the QSBC is the mediation entry point and can advise whether QCAT or courts are the next step: Leasing disputes - Queensland Small Business Commissioner.

Why this matters: mediation can produce a negotiated release of the deposit or a narrowed dispute that is easier and cheaper to litigate if mediation fails.

Step 5 — Understand key jurisdictional differences and next steps if mediation fails

State rules differ. For example, Victoria’s retail lease regime requires landlords to hold retail lease deposits in an interest‑bearing account and includes clear timing obligations for returning deposits in retail contexts; see the VSBC guidance on security deposits for details: Security deposits | Victorian Small Business Commission. By contrast, Queensland guidance notes there is no single legislative rule for how commercial deposits are held and urges mediation and tribunal pathways: Ending a lease | Business Queensland.

South Australia’s Retail and Commercial Leases Act provides a concrete example of a state that has specific statutory provisions about returning originals of bank guarantees; the Act text is available here for reference: Retail and Commercial Leases Act 1995 (SA).

If mediation does not resolve the dispute, the typical route is a specialist tribunal (VCAT in Victoria or QCAT in Queensland) or the appropriate state court. In Victoria, the VSBC can certify matters for VCAT; the VSBC FAQs explain that pathway: FAQs | Victorian Small Business Commission.

What outcomes to expect, and when to get legal advice

Possible outcomes range from full release of the deposit, to partial return after agreed deductions (backed by invoices), to a tribunal order for repayment plus interest or costs depending on the tribunal and facts. Because rules and remedies depend on the lease, the security type and state law, get qualified legal advice if the sum is large, the technical building issues are complex, or the landlord claims major deductions.
