Personal Property and Secured Transactions in Australia

Introduction

Personal property law in Australia underwent a fundamental transformation with the commencement of the Personal Property Securities Act 2009 (Cth) (PPSA) on 30 January 2012. The PPSA replaced a fragmented and inconsistent collection of Commonwealth, state, and territory laws governing security interests in personal property — including the Bills of Sale Act legislation, the Companies Act charges registration system, and state-based laws on chattel mortgages, hire purchase, and conditional sales — with a single, comprehensive national regime. The PPSA, modelled on Article 9 of the Uniform Commercial Code (United States) and the Personal Property Security Act (Canada), establishes a functional approach to security interests based on a single national register: the Personal Property Securities Register (PPSR).

The Scope of the PPSA

The PPSA applies to security interests in personal property. Personal property is defined inclusively as all property other than land (s 10): it encompasses both tangible property (goods, inventory, equipment, vehicles, crops) and intangible property (receivables, intellectual property, negotiable instruments, investment entitlements, and licences). The PPSA also applies to certain deemed security interests — transactions that function as security even though they take the legal form of a sale or lease, such as retention of title arrangements, hire purchase agreements, and finance leases.

The definition of a security interest in s 12 is functional rather than formal. A security interest is an interest in personal property created by a transaction that, in substance, secures the payment or performance of an obligation. This functional approach is the defining feature of the PPSA: the legal form of the transaction is irrelevant to its characterisation as a security interest. A consignment that is in substance a security arrangement, a sale of accounts or chattel paper, and a commercial consignment (in which the consignor retains title) are all treated as creating security interests for PPSA purposes.

Attachment and Perfection

A security interest attaches to collateral when two conditions are satisfied: (i) value is given by the secured party (typically the provision of credit); and (ii) the grantor has rights in the collateral or the power to transfer rights in it (s 19). Attachment determines when the security interest becomes enforceable against the grantor. A security interest may attach to after-acquired property (a floating charge is treated as a security interest in a circulating asset pool) and may secure future advances.

Perfection of a security interest is the process by which a secured party protects their priority against third parties, particularly other secured creditors and the grantor’s liquidator or trustee in bankruptcy. A security interest may be perfected by: (i) registration on the PPSR; (ii) possession of the collateral; or (iii) control of the collateral (for certain types of collateral, including investment entitlements and letters of credit). The default method of perfection is registration on the PPSR.

Registration is effected by filing a financing statement on the PPSR, which identifies the grantor and the collateral. The registration is registration by description: the collateral may be described by specific item, by category (e.g., “all present and after-acquired property”), or by a combination of both. The PPSR is a notice-filing system: the financing statement gives notice of the existence of a security interest but does not require the creation or attachment of that interest to be verified at the time of registration.

Priority Rules

The PPSA establishes a comprehensive set of priority rules to resolve competing claims to the same collateral. The fundamental rule is the first to perfect or first to register rule in s 55(3): where two or more security interests are perfected, priority is determined by the order of registration or perfection, whichever is earlier. This rule displaces the common law and equitable priority rules that applied prior to the PPSA, including the rule in Dearle v Hall and the principle that a legal interest prevails over an equitable interest.

The general priority rule is subject to numerous exceptions. The most important is the Purchase Money Security Interest (PMSI) super-priority, governed by ss 62–65 of the PPSA. A PMSI arises where a secured party provides credit to enable the grantor to acquire the collateral (for example, a vendor who retains title until payment, or a financier who lends money specifically to purchase particular goods). The PMSI holder obtains priority over earlier-registered security interests (including a general security agreement covering all present and after-acquired property) provided that the PMSI is perfected by registration within the prescribed time: 15 business days for inventory (s 62(2)) and 15 business days for non-inventory collateral (s 62(3)), measured from the time the grantor obtains possession of the collateral.

The PMSI is essential to the functioning of supply-chain financing. Without PMSI priority, a supplier of goods on retention of title terms would rank behind the purchaser’s existing secured creditor (typically a bank with a registered security interest over all of the purchaser’s assets). The PMSI ensures that suppliers and purchase-money financiers can obtain priority for the specific collateral they have funded.

Enforcement and Default

The PPSA provides a statutory enforcement regime that applies when the grantor is in default under the security agreement (Pt 4). The secured party may take possession of the collateral, sell it, or retain it in satisfaction of the debt (the Canadian-style strict foreclosure option). The secured party must give notice to the grantor and other interested parties before exercising enforcement rights, and the sale must be conducted in a commercially reasonable manner (s 131). The grantor retains the right to redeem the collateral before it is disposed of (s 142).

The enforcement provisions of the PPSA interact with the Corporations Act 2001 (Cth) in the context of corporate insolvency. The appointment of a liquidator, administrator, or receiver to the grantor triggers the PPSA’s vesting provisions: certain security interests that were not perfected at the time of the appointment vest in the grantor (s 267), meaning the secured party loses their priority. This creates powerful incentives for secured parties to ensure that their security interests are perfected before the onset of insolvency.

The Interaction with the Corporations Act

The relationship between the PPSA and the Corporations Act 2001 (Cth) is critical in commercial practice. The PPSA replaces Part 2K of the Corporations Act, which formerly required registration of company charges with the Australian Securities and Investments Commission (ASIC). Charges registered under the old regime were migrated to the PPSR upon commencement. The PPSA also modifies the treatment of circulating assets (the PPSA equivalent of the floating charge): a security interest in circulating assets has lower priority than certain statutory claims (including employee entitlements) under s 561 of the Corporations Act.

The vesting rule in s 267 of the PPSA applies when a security interest is not perfected before the appointment of a liquidator, administrator, or receiver. The unperfected security interest vests in the grantor, and the secured party is treated as an unsecured creditor. This rule has been the subject of extensive litigation and commentary. The Full Federal Court in Re OneSteel Manufacturing Pty Ltd [2017] FCAFC 175 held that the vesting rule applies even where the secured party’s failure to perfect was inadvertent, underscoring the importance of timely registration.

Sale of Goods and Nemo Dat

The sale of goods in Australia is governed by state legislation derived from the Sale of Goods Act 1893 (UK): the Goods Act 1958 (Vic), the Sale of Goods Act 1923 (NSW), and equivalent statutes in other states. The legislation governs the formation of contracts of sale, the passing of property (title) from seller to buyer, the transfer of risk, and the seller’s duty to deliver goods that conform to the contract.

The nemo dat quod non habet rule provides that a seller cannot transfer better title than they possess. A buyer obtains no title if the seller did not own the goods. The Sale of Goods Act provides exceptions to the nemo dat rule, including: (i) sale by a mercantile agent (factor) who has possession of goods with the owner’s consent; (ii) sale under a voidable title; (iii) sale by a seller in possession who has already sold the goods but retains possession; and (iv) sale by a buyer in possession who has not yet paid. The PPSA interacts with the nemo dat rule by providing that a buyer of goods takes free of a security interest if the buyer purchased the goods for new value and without actual knowledge of the security interest (the buyer in ordinary course of business protection under s 46).

Bailment

Bailment is the delivery of goods by the bailor to the bailee on terms that require the bailee to return the goods or deal with them in a specified manner. Bailment is a common law concept that survives the PPSA, but the PPSA applies to certain bailments that are in substance security arrangements. A finance lease (a bailment for a fixed term that does not allow the lessee to terminate early) is treated as a PPSA security interest. A true lease (a short-term hire arrangement) is not a security interest and is not subject to the PPSA registration requirements, though the lessor’s title is protected by possession.

Choses in Action

Choses in action are intangible personal property rights that can be enforced only by legal action, not by taking physical possession. Examples include debts, shares, patents, copyright, and rights under a contract. The assignment of a chose in action is governed by the common law and statute; the Property Law Act in each state (e.g., Conveyancing Act 1919 (NSW), s 12) provides for the legal assignment of debts and other choses in writing. The PPSA applies to security interests in choses in action, including assignments of receivables by way of security.

Equities and Equitable Interests

The PPSA does not apply to equities — a term defined in s 8(1)(b) as equitable interests other than security interests. The distinction between a security interest (which is registrable under the PPSA) and an equity (which is not) has generated difficult questions of characterisation. Mere equities (such as the right to rescind a contract for misrepresentation) are not registrable. Equitable interests (including the interest of a beneficiary under a trust and the interest of a partner in partnership property) are also excluded from the PPSA.

Conclusion

The PPSA has transformed Australian personal property law. The functional approach to security interests, the single national register, and the comprehensive priority rules have brought coherence and efficiency to secured transactions. The system is still evolving, with ongoing litigation clarifying the boundaries of the PPSA and its interaction with the Corporations Act, the sale of goods legislation, and the common law and equitable principles that continue to regulate personal property. For commercial lawyers, the PPSA is now the foundational framework for understanding and structuring secured transactions in Australia.
