Shortly (even on the next day if possible) after the armistice, Japanese warships appear off the coast of New Caledonia, Wallis&Fortuna and French Polynesia. Some French possessions offer brief resistance, others don't, but all of the above are occupied.
1. Would Britain and/or the US immediately go to war over this? (my guess is no, just institute embargo ala OTL)
2. Would Australia consent to having their best units sent to Egypt, with the Japanese so close to home? (my guess is again no, which puts the British into something of a predicament)
3. What kind of butterflies can we expect wrt the Pacific war?
