Where the register points next

training.gov.au points at nothing after TLI31921: it is the current product, and no replacement is listed.

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.

    The register records this supersession but attaches no note on what changed.

Official documents on the register

What training.gov.au lists for TLI31921 and for its training package TLI (release 16.0), with the name and date the register publishes for each file. We link them; we have not read them, and nothing on this page is taken from their contents.

Is TLI31921 on your scope?

This page is the register's record of one product. What it cannot tell you is whether TLI31921 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Enter your RTO number and we read every product on your live scope against training.gov.au and tell you which ones are superseded and which replacements the register flags not equivalent.

Public code, nothing else. We read your live scope from training.gov.au and answer here — we keep neither the code nor the answer; what remains is the two-minute abuse counter described on our privacy page.

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 TLI31921 is made of

training.gov.au lists 36 units for TLI31921: 11 core and 25 elective. To complete it, the register publishes a rule of 11 core units plus 7 electives — 18 units in all.

TLI31921 lists 3 units the register no longer recommends as current, and it publishes a replacement for every one of them. None is deleted without a way forward.

Core and elective are the register's own flags on the unit grid of the release read here. "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 13 October 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.
