Where the register points next
training.gov.au points at nothing after MSS50222: 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.
Official documents on the register
What training.gov.au lists for MSS50222 and for its training package MSS (release 5.0), 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 MSS50222 on your scope?
This page is the register's record of one product. What it cannot tell you is whether MSS50222 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Enter your RTO number and we read every product on your live scope against training.gov.au and tell you which ones are superseded and which replacements the register flags not equivalent.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 MSS50222 is made of

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 14 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.
