The priority of common law security interests (non-PPSA, not ASIC registrable charges) depends on the nature of the security interest (legal or equitable) in question, the time of its creation, whether there is any knowledge of prior interests and many other factors. The PPSA carries its own complexities about priority.
The priority of security interests under the PPSA depends on a number of factors. To summarise the key factors that will determine priority (this is by no means an exhaustive list):
(a) Priority time: the time of perfection creates what is called the priority time for a security interest. The general rule is that security interests rank for priority against each other by priority time1, subject to super-priority exceptions such as PMSIs and security interests perfected by control;
(b) The type of security interest: not all security interests are created equal under the PPSA, regardless of priority time. There is a more comprehensive list of the relative priorities of the various types of security interests under the PPSA in the priority waterfall discussion and diagram that are both set out later in this chapter. To give just a few key examples for the moment to introduce the flavour of priority under the PPSA:
among PMSIs there are “strong PMSIs” and “normal PMSIs”. Strong PMSIs are the title-based PMSIs, namely those of sellers, lessors and commercial consignors. Strong PMSIs defeat “regular” PMSIs granted by the same grantor in the same collateral.
PMSIs must comply with the PMSI Rules to qualify for super priority.
See paragraph 17.9.2 of Chapter 17 (Perfection) and paragraph 18.3.7 below for how to perfect PMSIs, and the PMSI Rules;
(c) The class of collateral: the class of collateral in question is relevant to priority for several reasons:
(i) first, control: there are six (6) classes of collateral against which security interests can be perfected by control. This matters because security interests perfected by control defeat other PPSA security interests in the same collateral, regardless of priority time or knowledge, except perfected transitional security interests2.
Security interests perfected by control are, however, subject to certain interests (not PPSA security interests) in the same collateral, which are those in the first three priority buckets of the priority waterfall. Briefly, these are
The six (6) classes of collateral which permit perfection of security interests by control are3:
(ii) second, serial-numbered property: registrations over serial numbered property must correctly list the serial number, otherwise:
(iii) third, inventory: if collateral is inventory in the hands of the grantor, then any PMSI security interests over the inventory must be registered (perfection for PMSIs is by registration only) either before supply of the goods to the grantor (for inventory that is goods) or before the PMSI attaches (for inventory other than goods). See the PMSI Rules discussed at paragraph 17.9.2 of Chapter 17 (Perfection) and paragraph 18.3.7 below for how PMSIs must be registered. This essentially means that PMSIs over inventory must be pre- registered, that is, registered before the inventory is supplied. Pre-registration is possible under the PPSA, provided the secured party has reasonable grounds to believe that a security interest will be taken in the future;
(iv) fourth, circulating assets: if collateral is a circulating asset, for instance inventory and many accounts, then whether the secured party has control (not control in the sense of perfection by control, but similar) over the collateral will determine whether the security interest is treated as a circulating security interest (floating charge equivalent) or not. Circulating security interests under the PPSA are subordinated to employee entitlements and the liens of administrators, just as floating charges were so subordinated before commencement of the PPSA; and
(v) fifth, goods: the commingling and accession rules under the PPSA apply only to goods. These rules apply to determine priority where goods subject to security interests are attached to, mixed with or processed into other goods.
Accordingly, the PPSA has its own complex set of priority rules which are based around not only priority time, but also the nature of the security interests subject to a priority dispute, and the class of collateral.

4 A registration will be defective for being seriously misleading if it does not display the serial number for serial numbered property which is required by the PPS Regulations to be registered by serial number (PPSA section 165(a)). The PPS Regulations require that only consumer (used by individuals for household or domestic purposes) serial numbered property and commercial aircraft must be registered by serial number. Other serial numbered property may be registered by serial number.
