Ron, great to see, thank you for sharing!

Did they use any AP loads?

I have not seen an Australian AP projectile in 40mm Bofors.

Two Drill rounds. Wooden usually HB over V (H is missing). Hanson & Bricknell, Melbourne.
40MM DRILL 1956 MK3 MO

Two HES projectiles.
The yellow banded one is MO 9/52 and usually found loose.
This example was filled with red brick dust and recrimped by RSNES-M.
Regional Superintendant Navy Engineering Support Melbourne.
3/98 is the latest date I have seen. The latest case date was MF 1992 or 93?

Thank you for the additional images!

The “INERT” was also applied by the navy? Means this was an instructional item for classrooms?

Great photos and info Ron! I love the Bofors stuff (as you know).

I believe the 306 fuze was developed by Australia in the 1970s and used into the 1990s.
