Being the world's dominant power gives you all sorts of options that could/should (not necessarily are) used to increase those things, though.
Not really. I heard the argument that having an overwhelmingly strong military improves economy by virtue of encouraging free trade, but I've never seen anything approaching actual proof for that (and I did look, I was interested). Having a strong/large military CAN have a somewhat similar effect for plan-based economies, but never for capitalist or regulated capitalist ones.
That's the thing, "global power", "position on the world chess board" and so forth is not at all the same as quality of life of civilians, and the two are really not related. Or if they are, there is not serious proof of that (if you provide a paper that shows otherwise, I will read it, because I have been looking for one).

There are many and varied reason why Australia hasn't been attacked, but powerful and warlike allies such as the US is a definite factor.
I don't think this is true. I would, however, say that Australia NOT being warlike is a definite factor. Correlation vs. causation, etc.

Again, not saying I agree with that the line of thinking which requires such a massive expenditure, but there are reasons for it.
This I agree with completely. I just don't think these reasons have anything to do with quality of life of civilians, and are instead concerned, partly, with the enormous military industrial complex, and even more so with the massive propaganda tool that the international status of the US military has turned into. In other words, (seriously) reducing the expenditures on US military is just about impossible for any single politician, even if it's absolutely the right thing to do.
I think we've been discussing this wrong though. I've been saying that having an overwhelmingly strong military has absolutely zero effect on civilians' quality of life, you are saying it has a small positive one, but may not be worth it. I think the latter is a better way of looking at it - what matters is the ratio of increase (assuming it's an increase, which is not actually guaranteed) to quality of life to money invested into the organization. I.e., quality per dollar. I think here you and I agree that the number is far too low to justify investing any more, even if we can't quite agree on its magnitude.
