When must new enrolments into DEF41812 stop?

New enrolments are not permitted from 24 January 2014 — one year from the date the replacement was included on the National Register (s 14(1)(a)(i) of the National VET Regulator (Compliance Standards for NVR RTOs and Fit and Proper Person Requirements) Instrument 2025 (F2025L00355, in force 1 July 2025)), or from a later date if ASQA has approved otherwise for your organisation.

Is there a deadline for learners already enrolled in DEF41812?

Learners already enrolled have no fixed deadline: they complete the product and are issued their AQF certification, or transfer to the replacement, in a timely manner (ASQA guidance, read live 25 August 2026).

Where the register points next

Each step below is one supersession training.gov.au publishes between two products. The label on the rail is the equivalence the register declares for that step — not our reading of it.

The register does not list a current endpoint for this chain: DEF42712 is the last product it points at, and DEF42712 is not marked current either.

What the register says changed

These are the mapping notes training.gov.au attaches to each supersession, quoted as the register writes them. They are the only public record of what actually changed between two versions.

Is DEF41812 on your scope?

This page is the register's record of one product. What it cannot tell you is whether DEF41812 sits on your own scope today, or what else on that scope has moved without anyone noticing. Enter your RTO number and we read every product on your live scope against training.gov.au and tell you which ones are superseded and which replacements the register flags not equivalent.

Whether a supersession requires anything of you, and what, sits with you and your regulator. This page maps what the register records; it does not make that judgement. If the difference between an equivalent and a non-equivalent replacement is the question, we wrote it up in equivalent vs not equivalent.

What DEF41812 is made of

training.gov.au lists 56 units for DEF41812. It does not mark them core or elective: the unit grid records N/A for every one of them. The register does not publish a completion rule in units for this product, so we do not state one. What it takes to complete the product is in the packaging rules on training.gov.au.

The register publishes this unit grid without a core or elective flag, so this page does not split it into core and elective. "Not current" means training.gov.au no longer recommends that unit for use inside this product — it does not say anything about the product itself.

Source: this product on training.gov.au, Australia's national training register — or go straight to the units it requires. The rule itself is item 14 of F2025L00355, and ASQA publishes the extensions it has granted. Read on 28 August 2026 UTC. Every code, title, date, status and equivalence flag on this page is the register's; nothing here is estimated or inferred, and where the register publishes nothing we say so.
