A Commercial Lease Agreement is a legally binding contract between a landlord and a tenant for the leasing of commercial, retail, or industrial premises in Australia. Unlike residential tenancies, which are regulated by comprehensive consumer protection legislation, commercial leases are primarily governed by the principles of contract law, with the additional overlay of state-specific Retail Leases Acts where the premises are used for retail trade.

Australia does not have a single national commercial leasing law. Instead, each state and territory has its own legal framework. For retail premises, the applicable Acts include the Retail Leases Act 1994 (NSW), the Retail Leases Act 2003 (VIC), the Retail Shop Leases Act 1994 (QLD), the Commercial Tenancy (Retail Shops) Agreements Act 1985 (WA), and the Retail and Commercial Leases Act 1995 (SA). These Acts provide mandatory protections for retail tenants including minimum disclosure requirements, restrictions on certain outgoings, minimum lease terms (in some states), dispute resolution mechanisms, and limitations on the landlord's ability to refuse consent to assignment.

For non-retail commercial premises (offices, warehouses, industrial properties), the lease is largely a matter of private negotiation between the parties, subject to general contract law principles, the GST Act, and any applicable planning or building laws. In practice, commercial leases in Australia follow standard market conventions developed by the Law Society and Real Estate Institute in each state.

Key features of an Australian commercial lease include the definition of the permitted use (which must comply with planning zoning), the rent payable and GST treatment, the mechanism for rent review (CPI, fixed percentage, or market), outgoings contributions, the security deposit or bank guarantee, make good obligations at the end of the lease, restrictions on assignment and subletting, insurance requirements, and any option to renew the lease for a further term.

A Commercial Lease Agreement is required whenever a landlord grants a business tenant the right to occupy commercial, retail, or industrial premises in Australia in exchange for rent. This includes arrangements for retail shops, restaurants, cafes, offices, warehouses, factories, showrooms, medical suites, and any other business premises.

You should use a commercial lease agreement when entering into any arrangement for the use of business premises that will last more than one month. Even for shorter-term arrangements, a written agreement is strongly advisable to record the agreed terms and protect both parties.

Commercial lease agreements are essential in the following situations: when a business is setting up a new location and needs to formalise the arrangement with the property owner; when a landlord is renting out a commercial or retail property and needs to document the terms, including rent, permitted use, and security arrangements; when the lease is expiring and both parties wish to document the terms of a renewal or new arrangement; and when a business is acquiring another business that operates from leased premises, requiring an assignment of the existing lease.

For retail premises, additional protections apply under the state Retail Leases Acts. In New South Wales and Queensland, the landlord must provide a mandatory disclosure statement to the tenant at least seven days before the lease is entered into (or a shorter period if the tenant waives this right). Failure to provide the mandatory disclosure statement can give the tenant the right to terminate the lease within a specified period. It is therefore critical that both parties understand whether the Retail Leases Acts apply to their arrangement before the lease is executed.

A well-drafted Australian Commercial Lease Agreement should address all key commercial terms as well as the legal requirements of the applicable state legislation.

The parties and premises section must correctly identify the landlord and tenant by their full legal names and, where they are companies, their Australian Company Numbers (ACNs) and Australian Business Numbers (ABNs). The premises must be described with precision, including the address, floor area, and any inclusions such as parking, storage, or common areas. The description of permitted use is critically important — it should be specific enough to define what the tenant can do in the premises while broad enough to accommodate the tenant's business activities without requiring variations in the future.

The term and option section sets out the initial lease period and any right of the tenant to renew for a further term. In states where the Retail Leases Acts apply, the combined initial term and option periods may need to meet a minimum requirement. The option to renew should specify the period of notice required and the conditions for exercise (including no existing breach).

The rent and GST section must state the base rent (exclusive of GST), the payment frequency, and the method of payment. All commercial rent in Australia is a taxable supply for GST purposes, and the landlord must issue valid tax invoices. The rent review section must specify the review mechanism (CPI, fixed percentage, or market), the review dates, and any ratchet clause preventing rent reduction.

The outgoings section is a key commercial term that distinguishes gross leases (where the landlord bears all outgoings) from net leases (where the tenant contributes to operating costs). Under the Retail Leases Acts of some states, certain outgoings — including land tax, capital expenditure on the building structure, and costs relating to other tenants — cannot be passed on to retail tenants.

The security section documents the type and amount of security (bank guarantee or cash security deposit) required, the conditions under which the landlord may draw on it, and the obligation to return it at the end of the lease. Make good obligations, insurance requirements, and assignment conditions are all key terms that should be clearly negotiated and documented to avoid disputes at the end of the lease.
