Several times recently in automatic deployment games I've had multiple territories in Asia but nowhere else to start from on another continent. I might have three of more of Astana, Beijing, Delhi, Manila, Novosibirsk, Tokyo, Yakutsk, and maybe Moscow (which is not in Asia). However, I was not in a good position to take Australia and usually someone else is.
Generally speaking, what do you do when you find yourself in this position? I understand it entirely depends on the game, but I'm tending to find that I get pushed out of North America if I try to expand that way and any run on Australia usually ends in both me and the strongest player in Australia losing the game. Africa is not an option unless I happen to hold Dubai or can take it from Delhi/Mumbai. Europe is very difficult to capture and hold from this position and if I try to hold onto a chunk of Asia then I find the Australian player will almost always overrun me. What would you do?
This question is mostly in regard to 4+ player standard games, but any advice is beneficial.
