You need different alliances...
How could we have had significant land battles on every continent in the world? That means North America, South America as well as Australia. A few bombing raids by the Japanese don't count, I'm talking combat at least on the level of North Africa.
You need different alliances, if the basic drift of history is the same from 1919 onwards...
Japan cannot wage expeditionary warfare in the western hemisphere, in any real sense, and the Germans and Italians have even less capacity to do so, in anything resembling reality.
The US and UK were the two greatest maritime powers; they were also the two greatest producers of POL (directly in the US case and indirectly in that of the UK); Japan was the third (maritime power, that is, not POL producer), and France was the fourth (maritme power). WW II was a conflict fuelled by oil, and without it, there's no chance of transoceanic offensives from the eastern hemisphere to the western, or from the northern to the southern.
Absent a different line-up of the Axis and the Allies, it is really going to be unrealistic to expect (for example) a Latin American nation to break with the western Allies and line up with the Axis. Anyone that did, of course, would be an economic and military backwater in short order.
A Japanese invasion of Australia, although certainly in the realm of the possible, requires the Japanese to commit very limited resources (merchant marine, naval, air, and military) to a type of warfare - continental and mobile - they didn't do well and which is going to be even more of a resource sink than (for example) New Guinea and the Solomons were historically...
It's worth remembering that even in the initial December, 1941-January, 1942 set of offensives by the Japanese, they never had more than about four divisions afloat simultaneously, and to do that, and sustain the expeditionary forces (military and aviation) necessary for the Malayan, Burmese, Philippines, and NEI campaigns took just about everything the Japanese had, and then some ...
Simply by going to war, the Japanese lost something like 30 percent of the shipping they had relied on to keep their peacetime economy going (since they required foreign flag shipping to that percentage)...
The USBS reports, which are available on-line, are excellent resources for understanding the economic and operational constraints on the Japanese war effort.
