I’m wondering how Japan was able to get enough stuff to Australia to smash it on R1 as well as doing everything else you mentioned.
You will always encounter these type of guys on the Internet. They can do what no one else can, apparently, and whether or not its technically impossible doesn’t matter. When you ask them to back their claims they disappear.
Yeah, I didn’t get that either. Japan has a strong naval influence in the Caroline Islands but only 1 infantry unit. Maybe on round 2 if they moved more land units down from Japan to the Carolines. That is assuming that Australia doesn’t block their naval passage with it’s 1 destroyer. That would cause a sea battle and push the invasion back to round 3. By then Australia could have 6 more infantry to defend with.
I’ve always found it hard for Japan to make a meaningful advance into Australia because they are so busy dealing with China and positioning themselves to take on the Brits and take the East Indies. Usually by the time Japan gets enough to go after Australia, the US is in the war and Japan has to deal with them.
