Is TDM50507 on your scope?
This page is the register's record of one product. What it cannot tell you is whether TDM50507 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Enter your RTO number and we read every product on your live scope against training.gov.au and tell you which ones are superseded and which replacements the register flags not equivalent.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 TDM50507 is made of
training.gov.au lists 27 units for TDM50507. 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.
