An Australian Loan Agreement is a legally binding written contract between a Lender and a Borrower that sets out the terms on which money is lent and must be repaid. It specifies the principal amount, the interest rate (if any), the repayment schedule, the security (if any), and the rights and obligations of both parties in the event of default. Loan agreements are used in Australia for a wide range of transactions, from informal personal loans between family members to complex commercial lending facilities between corporations.

In Australia, loan agreements are governed by a combination of Commonwealth and state legislation. The most important Commonwealth statute is the National Consumer Credit Protection Act 2009 (Cth) (NCCP Act), which, together with the National Credit Code (set out in Schedule 1 to the NCCP Act), regulates consumer credit contracts — that is, loans made to individuals or strata corporations for personal, domestic, or household purposes. Lenders providing consumer credit must hold an Australian Credit Licence issued by the Australian Securities and Investments Commission (ASIC) and must comply with responsible lending obligations, disclosure requirements, and hardship provisions.

Commercial loans — that is, loans made for business or investment purposes — are generally not regulated by the NCCP Act, though they remain subject to general contract law, equitable principles, and the Australian Consumer Law (which prohibits misleading conduct and unconscionable behaviour). The Corporations Act 2001 (Cth) governs loans involving corporate entities.

For secured loans, the Personal Property Securities Act 2009 (Cth) (PPSA) is fundamental. The PPSA created a single national register — the Personal Property Securities Register (PPSR) — for recording security interests in personal property (all property other than land). A lender who takes a security interest over the borrower’s personal property (such as receivables, equipment, or inventory) should register that security interest on the PPSR to perfect it. A perfected security interest has priority over unperfected interests and is protected in the event of the borrower’s insolvency.

GST implications must also be considered. Under the A New Tax System (Goods and Services Tax) Act 1999 (Cth), the lending of money and the payment of interest are input-taxed financial supplies and are generally not subject to GST. However, fees and charges associated with the loan may be taxable supplies, and lenders registered for GST should issue tax invoices for any taxable supplies.

A written Loan Agreement is essential whenever money is lent from one party to another, regardless of whether the parties are individuals, businesses, or a combination. Without a written agreement, disputes about the amount lent, the repayment terms, and whether the loan was a gift rather than a debt can be extremely difficult to resolve.

You should use a Loan Agreement in Australia whenever:

You are lending money to a family member or friend and want to document the loan formally to avoid misunderstandings and protect the relationship. The agreement records that the money is a loan (not a gift) and sets out when and how it must be repaid. In an estate context, an undocumented loan may be treated as an advancement from an estate or a gift, which can have significant tax and estate planning implications.

You are a business lending money to another business, a supplier, or a related company. Commercial loan agreements protect the lender’s position and can include security interests registered under the PPSA to give the lender priority over other creditors in the event of the borrower’s insolvency.

You are an investor or private lender providing finance to a property developer, startup, or small business. A well-drafted loan agreement with appropriate security, default provisions, and enforcement rights is critical for protecting your investment.

You require finance for your business and are entering into a loan arrangement with a non-bank lender. A written agreement ensures that both parties understand the terms and that the arrangement cannot be characterised as equity rather than debt.

You are a trustee of a superannuation fund making a limited recourse borrowing arrangement (LRBA) under section 67A of the Superannuation Industry (Supervision) Act 1993 (Cth). LRBAs have strict documentary requirements and must be structured as complying loan agreements.

A Loan Agreement is also important for taxation purposes. The Australian Taxation Office (ATO) requires loans between related parties (such as loans from a company to its shareholders or associates, or loans from a trust to its beneficiaries) to comply with the Subdivision EA rules in Division 7A of the Income Tax Assessment Act 1936 (Cth), or the loan may be treated as an unfranked dividend or trust distribution and taxed accordingly.

A comprehensive Australian Loan Agreement should address several key elements to be legally effective and protect both parties.

The parties and their details must be clearly identified. For individual lenders and borrowers, full legal names and addresses are essential. For company parties, the Australian Company Number (ACN) or Australian Business Number (ABN) and the registered office address should be stated. For trustee-borrowers, the capacity in which they are acting (as trustee of the named trust) must be expressly stated.

The principal amount, currency (AUD), and loan purpose must be clearly stated. The loan purpose is particularly important because it determines whether the NCCP Act applies (personal, domestic, or household purpose) or whether the loan is a commercial loan.

The interest provisions should specify the annual interest rate as a percentage per annum, the method of calculation (for example, daily on the outstanding balance), and the treatment of unpaid interest. For consumer credit, the comparison rate and annual percentage rate must be disclosed in accordance with the National Credit Code. Default interest provisions should be included to compensate the Lender for late payment.

The repayment schedule must be precise. Whether repayment is by equal monthly instalments, interest-only with a balloon payment, or a single lump sum at maturity, the payment dates, amounts, and method of payment should be clearly specified.

For secured loans, the security interest clause must accurately describe the collateral, the nature of the security interest (fixed or floating charge, or both), and incorporate the necessary PPSA provisions. The PPSA waiver clause (waiving certain PPSA notification rights that are not required for commercial loans) is standard in Australian commercial lending documentation.

Default and acceleration provisions are critical. The agreement should list the events that constitute a default, provide appropriate notice and cure periods (at least 30 days for consumer credit), and set out the lender’s rights upon default including the right to accelerate the debt, enforce security, and pursue the borrower for any shortfall.

The GST clause should address the input-taxed nature of the loan and clarify the GST treatment of any associated fees and charges.

Governing law should specify the Australian state or territory whose law governs the agreement. Australia does not have a single uniform contracts law, and there are differences between the states in areas such as limitation periods, deeds, stamp duty, and land titles law.
