well its not like theres any other mods Australia can be in. You wouldnt understand cause all your countries can be in most mods like War of Independence for America and Napoleonic Wars obviously for Europe, Australia's big moment for its military happened in WW1. Around twice the amount of Australians died in WW1 then WW2, 10 times the amount that died in Vietnam. I Might as well try and get them in the mod as much as possible
EDIT: I can understand why people from small countries that took part but werent a big role would want units from there country in game
