Something to consider re: kit Australia could send to Ukraine. As much as one might wish for Australia to provide more support and material to Ukraine, one needs to consider both what Australia's strategic concerns are, particularly between now and ~2030, as well as what the limitations are on or of Australian defence industry.
For example, think about Australian 155 mm ordnance. How large are Australian warstocks of 155 mm munitions, and what condition are the warstocks in? How large does the ADF want or feel it needs to be, particularly if a potential conflict in the region were to break out?
From the manufacturing side of things and especially for defence kit which is not really something which can be produced for speculation on later sales, manufacturers really are not going to 'just build' munitions, they are going to build to fulfill orders. If one were to look at the
ADM article linked to a few posts back on the Rheinmetall NIOA munitions facility, then one would realize a few fairly significant things. First, the overall facility was apparently designed to produce up to 100k projectiles p.a. at full-rate production whilst running multiple shifts. Secondly, the total projected workforce is ~100, but right now the facility is only at ~60% staff. This is significant because without a large enough staff, there just will not be sufficient bodies to be able to carry out all the production and QA/QC functions needed to run across multiple shifts and meet the planned high production numbers. IMO not much would be gained in attempting a stress test until such a facility was much closer to being fully staffed as well as having production reach full rate.
