It's the price, not the book, that is not available

I thought I'd pass on an information gem/discovery, because particularly if you are an Australian Kindle owner, this may have also mis-led you.

Until I noticed I could see a price for a Kindle version in the middle.
So I clicked on that and arrived here:

So, now, as you can see, the mystery unravels.
The book is available to me, here in Oz, just not at the price Books on the Knob advertised which must be a price for US customers.
