How is a bank guarantee different from a cash bond?

A cash bond is the tenant's money held in a trust account. The landlord can only access it through agreed deductions or a tribunal order. A bank guarantee is the bank's money paid on the landlord's written demand, with no requirement to prove default first. Cash bonds tie up the tenant's capital. Bank guarantees do not. Most commercial leases require a bank guarantee over a cash bond for this reason.

Can a tenant stop a landlord drawing on a bank guarantee?

Rarely. The autonomy principle (Wood Hall Ltd v Pipeline Authority, 1979) treats the guarantee as independent of the lease dispute. A tenant can only obtain an injunction against payment in narrow circumstances: clear fraud by the landlord, or unconscionable conduct under the Australian Consumer Law. Disputes about whether the underlying default occurred are not enough.

Does a bank guarantee expire?

Most bank guarantees have no expiry date. They remain enforceable until the bank receives the original document back or written release from the landlord. Some are issued with a fixed expiry to limit the bank's exposure, common for terms longer than 3 years. The lease should require the tenant to replace any expiring guarantee at least 30 days before expiry, with the new guarantee in identical terms.

When must a landlord return a bank guarantee at lease end?

There is no statutory deadline. Best practice: return within 30 to 60 days of lease end, after confirming make-good is complete, all outgoings are reconciled and paid, no rent arrears remain, and no claims have arisen from the final inspection. Holding the guarantee beyond this window without active claims can expose the landlord to claims for unconscionable conduct.

How much is a bank guarantee in a NSW commercial lease?

Standard practice in NSW commercial leases is 3 to 6 months of gross rent including GST. For retail leases the Retail Leases Act 1994 (NSW) does not cap the amount but bond values are often 3 to 4 months. For high-risk tenants (new business, weak covenant) institutional landlords frequently require 6 to 12 months. The figure must be stated in the lease as a fixed dollar amount, not a formula.

Does a bank guarantee cover outgoings shortfalls?

Only if the lease defines outgoings shortfalls as a recoverable amount under the guarantee. Most leases word the guarantee broadly enough (rent, outgoings, any other monies payable) to capture reconciliation shortfalls. But if RLA s.28 reconciliation deadline was missed, the shortfall is no longer payable, so the guarantee cannot recover it either. Reconciliation discipline preserves guarantee coverage.

What is a bank guarantee for a commercial lease?

A bank guarantee is an unconditional undertaking issued by a bank to pay the landlord a specified sum on demand if the tenant defaults. The tenant arranges the guarantee through their bank, which holds the corresponding amount as security. The bank guarantee itself is delivered to the landlord at lease execution and held for the duration of the tenancy.

Unlike a cash bond, the money does not sit in the landlord's account or a statutory trust. The bank is the guarantor. If you make a valid demand under the guarantee, the bank pays regardless of whether the tenant agrees or contests the claim. The tenant's dispute with you is a separate matter.

Key point: A bank guarantee is unconditional. The bank does not adjudicate your claim. It pays the amount demanded up to the face value of the guarantee, provided your demand complies with the terms of the guarantee document itself.

What a bank guarantee document contains

The name of the issuing bank and branch
The name of the beneficiary (the landlord or the landlord's entity)
The guaranteed amount, expressed in Australian dollars
The expiry date, if any (some are open-ended, some expire on lease end)
The demand procedure: how you must present your claim in writing
The guarantee number, used to identify the instrument with the bank

Comparison

Bank guarantee vs cash bond

Both instruments secure the landlord against tenant default, but they work differently in practice. The choice matters for liquidity, dispute resolution speed, and the administrative burden on both parties.

Feature	Bank Guarantee	Cash Bond
Who holds the money	The bank (as collateral against the tenant's account)	Landlord holds cash, or held in trust by the agent
Interest	None to the landlord. The bank earns on the collateral.	Landlord may earn interest depending on agreement
Speed of recovery	Fast. Bank pays on demand within stated terms (typically 5-10 business days)	Available immediately if held in trust. Disputes can delay release.
Tenant dispute rights	Tenant can pursue landlord after payment, but cannot block the demand	Tenant can dispute disbursement and delay release through Fair Trading or court
Typical amount	3-6 months rent equivalent for commercial leases	Varies; less common in commercial, more common in retail and residential
NSW retail leases	Permissible under the Retail Leases Act 1994	Regulated; maximum amount set by the Act

Practical note: For commercial leases over 12 months, most sophisticated tenants and their lawyers prefer bank guarantees over cash bonds. The bank guarantee preserves the tenant's cash flow. The landlord's security position is equivalent or stronger, given the unconditional payment obligation.

Making a demand

When can a landlord draw on a bank guarantee?

You can make a demand under a bank guarantee whenever the tenant has defaulted under the lease and the lease entitles you to draw on the security. Common trigger events include:

Rent arrears that remain uncured after the notice period in the lease
Outgoings shortfall after reconciliation where the tenant fails to pay within the required period
Make-good obligations not completed at lease expiry
Damage to the premises beyond fair wear and tear
Lease repudiation or abandonment of the premises

The demand process

Read the guarantee document. Every bank guarantee specifies the exact demand procedure. Commonly this requires a written letter on your letterhead, signed by an authorised officer, stating the amount demanded and the basis of the demand.

Submit to the issuing bank branch. Present the demand in writing along with the original guarantee document. Some banks accept emailed demands; others require the original document to be returned before paying.

Bank pays within the stated period. Payment typically arrives within 5-10 business days. The bank does not assess whether your claim is valid on the merits. It confirms only that your demand complies with the form requirements in the guarantee.

Notify the tenant. While not always legally required, notifying the tenant before or at the time of demand is generally good practice and reduces the risk of injunctive relief applications.

Watch for expiry dates. Some guarantees expire on the last day of the lease term. If the tenant vacates with make-good obligations outstanding, and the guarantee has expired, you lose the security. Track expiry dates as a hard calendar reminder.

Returning the bank guarantee at lease end

Once the tenancy ends and all obligations under the lease have been satisfied, the landlord is required to return the original bank guarantee document to the tenant (or their bank) promptly. Most leases specify a timeframe of 14 to 30 days after the later of: the lease end date, completion of make-good, or resolution of any outstanding outgoings reconciliation.

Before returning the guarantee, confirm:

All rent and outgoings have been paid in full, including the final period
The outgoings reconciliation for the final year has been settled
Make-good inspections are complete and costs have been agreed or resolved
No damage claims remain outstanding
Keys have been returned and the premises formally surrendered

Do not return the guarantee as a goodwill gesture before make-good is complete. Tenants sometimes request early return, arguing the lease has ended. The guarantee secures all obligations, including post-lease obligations. Once returned, you have no instrument left if make-good defects are discovered during final inspection.

Partial draws before lease end

If you draw on the guarantee for, say, three months of arrears mid-lease but the tenancy continues, the lease should specify whether the tenant must top the guarantee back up to its original face value. Check your lease. If the top-up obligation exists, send the tenant a formal notice within the timeframe the lease requires.

BLOX tracks every bank guarantee expiry across the portfolio

Bank guarantee expiry dates are among the most frequently missed items in commercial property management. An expired guarantee with a tenant in arrears or poor make-good is money you cannot recover. BLOX logs every guarantee document, expiry date, and required notice period as a calendar obligation against each tenancy. You receive a reminder 90 days before expiry and again at 30 days.

If you have experienced a lease where the security expired or was never properly documented, or if you are uncertain whether your current agent has these systems in place, we can review your portfolio.
