How to Register a Security Interest on the PPSR: A Step-by-Step Guide for Australian Businesses

Registering a security interest on the Personal Property Securities Register (PPSR) protects your business if a customer or debtor enters insolvency. An unregistered security interest can be lost entirely when a company collapses. This guide walks you through every step of the PPSR registration process, from creating your account to avoiding the traps that catch even experienced business owners out.

If you supply goods on credit, lease equipment, or take personal property as security for a debt, PPSA registration is not optional. It is the difference between recovering your assets and proving a debt in a liquidation for cents in the dollar.

What Is the PPSR and Why Does It Matter?

The Personal Property Securities Register (PPSR) is an online register maintained by the Australian Financial Security Authority (AFSA). It records security interests in personal property, which means almost any property that is not land. Vehicles, equipment, plant, stock, receivables, intellectual property and livestock can all be registered on the PPSR.

The PPSR was established under the Personal Property Securities Act 2009 (Cth) (the PPSA), which came into force on 30 January 2012. Before the PPSA, Australia had a patchwork of state-by-state registers: Bills of Sale registers, Chattel Mortgage registers, motor vehicle encumbrance registers, and retention of title registers scattered across eight jurisdictions. The PPSA replaced all of them with a single national online register.

What the PPSA Changed

The PPSA fundamentally changed how security interests are created, perfected, and enforced. Under the old law, a supplier who sold goods on retention of title (ROT) terms generally retained ownership of those goods until payment, meaning they could repossess them from a customer who went into administration. Under the PPSA, ROT clauses are treated as security interests that must be registered on the PPSR to be enforceable against third parties, including an insolvency administrator.

This is the core risk. Section 267 of the PPSA provides that an unperfected security interest vests in the grantor (your customer) on the appointment of an external administrator or on the company being wound up. In plain terms: if you have an unregistered ROT clause and your customer enters voluntary administration or liquidation, your security interest disappears. Your stock, equipment, or assets become the property of the insolvent estate, available to all creditors, and you are left as an unsecured creditor proving a debt you may never recover.

Registration on the PPSR is the mechanism by which a security interest is perfected, that is, made effective against third parties including insolvency administrators. A perfected security interest survives the insolvency of the grantor and allows you to recover the collateral (or its proceeds) ahead of unsecured creditors.

Who Needs to Register on the PPSR?

You need to register on the PPSR if you fall into any of the following categories:

• Suppliers selling goods on credit with retention of title clauses. If your invoice or trade terms say ownership does not pass until full payment, you have a security interest that requires registration.
• Equipment lessors and financiers. Businesses that lease plant, machinery, vehicles, or technology to customers need a PPSR registration to protect their interest in that equipment if the lessee fails.
• Consignors. If you place goods on consignment, meaning the other party holds your goods for sale but has not yet paid for them, you have a security interest in those goods.
• Lenders taking personal property as security. Lenders who take a charge or mortgage over business assets (other than land) must register on the PPSR.
• Any business where goods or assets leave your hands before payment is received. If value transfers before money does, you have a security risk that PPSR registration can address.

The question to ask is simple: if this customer collapsed tomorrow, could you get your goods or money back? If the honest answer is “only if I have a PPSR registration,” then register.

Step-by-Step: How to Register on the PPSR

The registration process is completed entirely online at ppsr.gov.au. Here is the complete process.

Step 1: Create a Business Account on ppsr.gov.au

Go to ppsr.gov.au and click “Register.” You will create an account using your business ABN. Individual account holders can also register, but business accounts allow you to manage multiple registrations, set up delegated users, and access invoicing features. Once your account is verified, you can log in and begin creating registrations immediately.

Keep your login credentials secure. Your account will hold all of your active registrations, and access to the system is essential for renewals and amendments.

Step 2: Identify the Collateral Type

Before you begin a registration, you must correctly identify the type of collateral you are securing. The PPSR uses the following collateral categories:

• Motor vehicle, identified by VIN (Vehicle Identification Number). This applies to cars, trucks, motorcycles, trailers, and caravans.
• Watercraft, identified by hull identification number or registration.
• Aircraft, identified by manufacturer’s serial number.
• Other goods with a serial number, plant, machinery, or equipment with a manufacturer’s serial number can be registered as serial number collateral.
• General collateral, used for assets that do not have a serial number, such as stock in trade, general inventory, livestock, and accounts receivable. You describe the collateral in free text.
• All present and after-acquired property (ALLPAAP), a broad registration covering all present and future assets of the grantor. Commonly used by financiers and banks.

Getting the collateral type right matters enormously. A motor vehicle registered as general collateral instead of motor vehicle collateral by serial number will not be found by a serial number search, which means a buyer of that vehicle in the ordinary course of business may take it free of your interest.

Step 3: Identify the Grantor

The grantor is the person or company over whose property you are registering a security interest, usually your customer or debtor. You must get the grantor identity exactly right.

• Company grantor: Use the grantor’s registered company name and ACN (Australian Company Number). Do not use an ABN, a trading name, or a trust name unless those are the registered entity details. If you are dealing with a trustee company, register against the trustee (the registered company), not the trust.
• Individual grantor: Use the grantor’s full legal name and date of birth. Middle names matter, a registration against “John Smith” without a date of birth, when your debtor is “John Michael Smith,” can be challenged.

One of the most common and costly PPSR errors is registering against the wrong entity within a corporate group. If your customer trades through one company but the actual assets are owned by a related company, your registration against the wrong entity protects nothing.

Step 4: Choose the Registration Duration

You must choose how long your registration will remain active. The options are:

• Up to 7 years, appropriate for most trade credit and equipment lease arrangements. You can renew before expiry.
• 7 to 25 years, appropriate for longer-term finance arrangements.
• No end date (indefinite), appropriate for arrangements with no fixed term, such as ongoing ALLPAAP registrations.

Match the registration duration to your commercial arrangement. A registration that expires during the term of a lease or finance agreement leaves you unprotected for the remaining period. Set a calendar reminder to renew before expiry, an expired registration loses its priority date and must be re-registered, potentially with a later priority position.

Step 5: Pay the Registration Fee

As at the date of this guide, the government fees for PPSR registration (verified on ppsr.gov.au) are:

• Up to 7 years: $6.00
• 7 to 25 years: $25.00
• No end date: $115.00

Payment is made online by credit or debit card. There is no GST on these fees. Given the value of the assets you are protecting, the registration fee is one of the best-value risk management tools available to any Australian business. An unregistered $500,000 equipment fleet in a customer insolvency will cost you far more than the $6.00 it would have cost to register.

Step 6: Record the Registration Number

Once you complete registration, the PPSR system issues a registration number. Save this number immediately and store it against the relevant customer file, contract, or matter. You will need it to amend, renew, or discharge the registration. Without it, you will need to search the register to locate your own registration, an additional step and cost.

We recommend maintaining a PPSR register internally, a simple spreadsheet recording the customer name, registration number, collateral description, registration date, and expiry date for every active registration. Review it quarterly.

The 20-Business-Day Trap (s 588FL Corporations Act)

Section 588FL of the Corporations Act 2001 (Cth) is one of the most dangerous provisions for creditors who delay their PPSR registration. It operates as follows:

If a company grants a security interest and the security interest is registered on the PPSR more than 20 business days after the security agreement is made, and the company then enters external administration (voluntary administration, liquidation, or receivership) within 6 months of the registration date, the security interest is void against the liquidator or administrator. You lose your priority as a secured creditor.

This rule exists to prevent creditors from rushing to register security interests on the eve of an insolvency to gain priority over other creditors. But it catches legitimate creditors too, particularly those who:

• Are unaware of the PPSA registration requirement and register late after receiving legal advice;
• Register promptly but incorrectly, then re-register after fixing errors (the new registration date is what counts);
• Take over existing credit accounts without reviewing whether security interests were registered.

The practical rule: register before you hand over goods or advance funds. Do not wait until you have the signed agreement back. Do not wait for payment of the first invoice. Register on the day of (or the day before) the transaction. If you are taking over an existing customer relationship, audit the PPSR registrations immediately.

For a detailed analysis of how s 588FL operates in insolvency, see our post: Section 588FL and PPSA Security Interests: What Secured Creditors Need to Know When a Company Collapses.

Common PPSR Registration Mistakes

The PPSR system is straightforward but unforgiving. Small errors can invalidate a registration entirely. Here are the most common mistakes we see:

1. Wrong Grantor Identity

Using a trading name, trust name, or ABN when the correct identifier is the registered company name and ACN. Always verify the grantor’s identity on ASIC Connect before registering.

2. Wrong Collateral Description

A vague or incorrect collateral description, particularly for general collateral, can make it impossible to establish what your security interest actually covers. Be specific: describe the goods by type, model, serial number where available, and location if relevant.

3. Registering Against the Wrong Group Entity

In corporate groups, your contract may be with one entity but the assets may sit in another. Confirm which entity owns the collateral you are securing. You may need registrations against multiple entities.

4. ROT Clauses Not Drafted Correctly

A retention of title clause that is vague, inconsistent with the PPSA framework, or embedded in fine print on an invoice rather than a signed agreement may not constitute a valid security agreement under s 20 of the PPSA. The security interest must “attach”, meaning the debtor must have rights in the collateral and you must have given value. Get your standard terms reviewed.

5. Registering After the 20-Business-Day Window

As discussed above, late registration creates serious risk. The 20-business-day clock starts from the date the security agreement is made, not from when the goods are delivered or the invoice is issued.

6. Letting Registrations Expire

A registration that expires is treated as if it never existed from the point of expiry. Monitor your expiry dates and renew early. Note that renewing a registration does not reset its priority date, the original registration date is preserved on renewal.

7. Registering Motor Vehicles as General Collateral

Motor vehicles must be registered by VIN to be found in a serial number search. Registering a vehicle as general collateral by grantor name only means a buyer who searches by VIN will not see your interest, and may take the vehicle free of your security.

Searching the PPSR Before You Do Business

Just as important as registering your own security interests is searching the PPSR before you extend credit or accept property as security. A PPSR search tells you whether someone else already holds a registered security interest over the assets you are about to take, or over all the assets of a business you are about to extend credit to.

When to Search

• Before extending trade credit to a new customer, search by grantor to see whether banks or other financiers hold ALLPAAP registrations over the customer’s assets.
• Before buying second-hand equipment, vehicles, or plant, search by serial number or VIN to ensure no security interest is registered against that specific asset.
• Before taking an assignment of a debt or book of receivables, search the PPSR to assess what security interests already exist.

How to Search

Go to ppsr.gov.au. Casual (non-account) users can search for $2 per search. Account holders pay $3.40 per search (invoiced). You can search by:

• Grantor (individual or company), shows all registrations against that person or entity
• Serial number, shows registrations against a specific vehicle (VIN), watercraft, aircraft, or other serial-numbered property

What a Search Result Means

A result showing an existing registration does not necessarily mean you cannot deal with the property, but it does mean you need to investigate. It may mean the asset is subject to a finance agreement, a ROT claim, or a bank charge. If you are buying the asset, the security interest may follow it to you. If you are extending credit to the grantor, you may be an unsecured creditor if the grantor fails.

A nil result (no registrations found) is not a guarantee, it confirms only that no registration appears on the PPSR as of the search date. It does not reveal unregistered interests or interests registered in other jurisdictions.

PPSR and Insolvency: What Happens When Your Customer Collapses

The PPSR is most important when your customer enters external administration. Here is what happens, and what you need to do immediately.

Perfected vs Unperfected Security Interests

A perfected security interest is one that has attached (s 20 PPSA) and been registered on the PPSR (s 21 PPSA). A perfected security interest survives the insolvency of the grantor. You can recover the collateral from the administrator or liquidator, or claim its proceeds with priority over unsecured creditors.

An unperfected security interest, one that has not been registered, vests in the grantor on the appointment of an external administrator (s 267 PPSA). This means your security interest is extinguished. Your goods become the property of the insolvent estate. You rank as an unsecured creditor.

What to Do Immediately When a Customer Collapses

1. Check your PPSR registration immediately. Log in to ppsr.gov.au and verify that your registration is current, correctly describes the collateral, and identifies the right grantor. If there is a problem, take legal advice immediately, there may still be options.
2. Do not remove goods from the customer’s premises without authority. Once an administrator or liquidator is appointed, you need their consent or a court order to recover assets, even goods you believe you own under a ROT clause. Self-help recovery without proper authority may expose you to liability.
3. Contact the administrator or liquidator early. Notify them in writing of your security interest, provide your registration number, and assert your rights. Administrators and liquidators deal with multiple creditors and move quickly, if you are slow, assets may be sold before your claim is assessed.
4. Lodge a proof of debt and your secured creditor claim. Even if you have a valid PPSR registration, you should lodge a proof of debt and provide evidence of the registration to support your claim as a secured creditor.

Frequently Asked Questions

How much does it cost to register a security interest on the PPSR?

As at 2025, the government fee to register a security interest on the PPSR is $6.00 for registrations of up to 7 years, $25.00 for registrations of 7 to 25 years, and $115.00 for registrations with no end date. These fees are paid online directly to AFSA through ppsr.gov.au and do not attract GST. There are no additional costs to register online.

What is the difference between the PPSA and the PPSR?

The Personal Property Securities Act 2009 (Cth) (the PPSA) is the federal legislation that governs security interests in personal property across Australia. The Personal Property Securities Register (PPSR) is the online register created under the PPSA where security interests are recorded. The PPSA is the law; the PPSR is the register established by that law.

Do I need a lawyer to register on the PPSR?

You do not need a lawyer to create a PPSR registration, the process is entirely online and designed to be completed by business owners. However, legal advice is strongly recommended when setting up your trade terms (to ensure a valid security agreement exists), when dealing with complex collateral arrangements, and when asserting your PPSR rights in an insolvency. Getting the legal foundation right is more important than the registration itself.

What happens if my PPSR registration expires?

If a PPSR registration expires, your security interest becomes unperfected from the expiry date. Under s 267 of the PPSA, an unperfected security interest vests in the grantor on the appointment of an external administrator, meaning you lose it entirely in an insolvency that occurs after your registration lapses. Renew your registrations before they expire. Renewal preserves your original priority date.

Can I register a security interest over a trust’s assets?

Yes, but the registration must be made against the trustee of the trust (the legal entity holding the assets), not the trust itself. A trust is not a legal person and cannot be a grantor on the PPSR. Identify the correct trustee entity and register against that entity using its ACN. If the trust has a corporate trustee, search ASIC Connect to find the current trustee and its ACN before registering.
