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.
- PUA40402Superseded — equivalentCertificate IV in Public Safety (Explosive Ordnance Maintenance)
- =equivalent
- PUA40406Superseded — equivalentCertificate IV in Public Safety (Explosive Ordnance Maintenance)
- =equivalent
- PUA40410Superseded — equivalentCertificate IV in Public Safety (Explosive Ordnance Maintenance)
- =equivalent
- DEF40412Superseded — equivalentCertificate IV in Explosive Ordnance Maintenance
- =equivalent
- DEF42115Superseded — equivalentCertificate IV in Explosive Ordnance Maintenance
training.gov.au publishes 2 replacements for DEF40412. This rail follows DEF42115; the other: DEF42215.
The chain does not end here: we draw five steps at most, and training.gov.au points on from DEF42115 to DEF40120, which it flags =equivalent to DEF42115. 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 PUA40402 on your scope?
This page is the register's record of one product. What it cannot tell you is whether PUA40402 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Enter your RTO number and we read every product on your live scope against training.gov.au and tell you which ones are superseded and which replacements the register flags not equivalent.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 PUA40402 is made of
training.gov.au did not return a unit list for PUA40402 when this page was read. We would rather leave the gap visible than guess at it.
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.
