could you two please check one thing for me.... are these all australian made parts or just stuff the australian navy uses?
it might be an good idea to split these 2..... especially as an 'aus navy parts sheet' can get quite big without any special stuff added (look at the dutch navy part sheet, half the stuff is already on the RN and US parts sheets) while australian produced stuff could be added on one sheet of various nations which produce not enough to really need their own sheets, but important enough to have their equipment represented (apart from australia, I would also add for example canada to that list)
just an idea/suggestion, and if you would say make an multination sheet, I will be glad to help a bit
