Most of the Australian politics and military background comes from one of teh members of the team putting the background to TBO together, a guy called Shane Rogers (posts as The Argus on Ezboard). I've emailed him for a detailed explanation of the rationale for the incorporation of New Zealand into Australia and will post it when it arrives (this may take a few days).
In a more general sense, one of the precepts that commonly occurs in alt-hist that deals with the early days of WW2 is that, in the event of a British collapse, the Commonwealth fights on. Now, there are problems with that concept, not the least being
A - How?
B - Where?
So, in putting the backstory of TBO together, we decided to have a look at what would be involved in the Commonwealth fighting on. This immediately gave rise to a third question.
C - Why?
It very quickly became apparent that none of the three questions could easily be answered. For example, why should India fight on in the event of a British collapse in 1940? And if they did, what would they do? The answers to those turned out to be so complex that they form the subject of the next book in the TBO series - "A Mighty Endeavor".
One of the major problems that quickly becomes apparent is that the Commonwealth was a fairly tightly integrated whole with the UK as the central prop. Kick out that central prop and the whole system falls apart. The complexities of that issue are enormous and I can't go into them in a shortish post like this but in essentials, Australia and the rest of the Commonwealth are left with the wreckage of an economic system that was never designed to operate to their advantage and which severely distorted their basic economic structure.
New Zealand is a pretty good example. It produces agricultural products, butter, cheese, lamb, few other things. Who is going to buy them? The U.S. certainly isn't.
So,
if we make the standard alt-hist assumption 'the Commonwealth fights on'
then we have a lot of economic restructuring to do. The factfiles dealing with TBO give quite a bit of background on this and help to fill in some of the details. It's one of those If/Then questions, if we make a basic assumption, then what are the consequences and how do we make that assumption work.
I don't have detailed knowledge of Australian cultural or economic history so I turned to people who do for advice. Shane was one of those who stepped forward with input (early on, I validated what he was saying a gainst other people with specific knowledge of the areas under discussion and and their verdict was an enthusiastic approval). Shane came up with the rationale for the incorporation of New Zealand into Australia based on the dire economic situation (I can't stress enough just how bad the economics are; the situation if we remove the UK from the center of the Commonwealth at that time is utterly catastrophic) and I accepted that. Frankly, it isn't that important, its a backstory detail that has utterly no effect on the timeline.
Another reason, by the way, behind the way the events in the Far East was structured was a desire to get away from the standard fare of alt-hist stories. I was tired of seeing Japan, China etc etc etc being the major world powers, I wanted to ask the question, what would happen if somebody arrives from out of left field, a country (or countries) which were previously of little or no account suddenly find themselves moving towards the center of the world stage (much as, for example, the UK did in the 17th and 18th centuries - NAM Rodgers Sovereinty of the Seas and Command of the Oceans look at this process in great and very readable detail). How do those countries cope with the problems? More fundamentally, what is their response to moving to the center of the world stage, more precisely how do they do it?
In setting the situation up, I was sorely tempted to use the Philippines as the Asian country that finds itself in the center of world affairs and has to step up to the plate. In the end, I settled on Thailand for a wide variety of factors, not least being its a country I do have detailed knowledge of and have many well-placed friends there. From the need to restructure much of the world's economy caused by the (temporary) removal of the UK from the Commonwealth and the need to create a political structure in that part of the world grew The Triple Alliance. New Zealand is one not very important part of that process.
As I said earlier, I've asked Shane for a more detailed account of the whys and hows of the New Zealand incorporation into Australia and will post the response when I get it. As I recall, it was essentially a result of the economic catastrophe that left very little in the way of alternatives.
