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.
- TDM40207Superseded — equivalentCERTIFICATE IV IN TRANSPORT & DISTRIBUTION (MARINE ENGINE DRIVING - GRADE 1)
- =equivalent
- MAR40213Superseded — equivalentCertificate IV in Maritime Operations (Marine Engine Driver Grade 1)
- =equivalent
- MAR40513Superseded — equivalentCertificate IV in Maritime Operations (Marine Engine Driver Grade 1 Near Coastal)
- =equivalent
- MAR40518Superseded — equivalentCertificate IV in Maritime Operations (Marine Engine Driver Grade 1 Near Coastal)
- =equivalent
- MAR40220Superseded — equivalentCertificate IV in Maritime Operations (Marine Engine Driver Grade 1 Near Coastal)
The chain does not end here: we draw five steps at most, and training.gov.au points on from MAR40220 to MAR40224, which it flags =equivalent to MAR40220. Follow it from that page.
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 TDM40207 on your scope?
This page is the register's record of one product. What it cannot tell you is whether TDM40207 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Enter your RTO number and we read every product on your live scope against training.gov.au and tell you which ones are superseded and which replacements the register flags not equivalent.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 TDM40207 is made of
training.gov.au lists 19 units for TDM40207. 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.
