What we refer to as spare ribs here are shown a few pages away, labeled as a belly rack.
Taking a look at the PDF that Celia pointed us to, yes, it's clear that what we in the USA call "spare ribs" are most like the Australian "belly rack" cut. But not quite the same. The "belly rack" and the "spare ribs" photo next to it both have the skin and belly fat layers still on. In the US, this is trimmed off and marketed separately as "pork bellies" (of commodity trading fame) or "fresh bacon" (both with skin on). When smoked and cured, with skin removed, it is the familiar everyday bacon. What's left is the underpart of the "belly rack"--just the rib bones and the meat between them, and the brisket flap on the silver underside. This is the cut that Americans call "spare ribs". If the brisket flap and the chine bone connecting the ribs are removed, the result is called "St. Louis Cut" or "Chinese Cut" spare ribs. That is the preferred cut for US Southern-style barbecued spare ribs. St. Louis cut spare rib racks generally weigh three pounds or less (hence the term "3 and down"). A rack with the chine bone and brisket intact will be 4 pounds or more.
These are a larger and tougher cut than the loin ribs shown as "American spare ribs" on page 8 of the PDF. You can see from the diagram on page 6 of where on the animal they come from why in the USA this cut is called "baby back ribs". Aside from the difference in name, they are the same cut.
It's fascinating how different countries have managed to find different ways of cutting up a pig. And similar names for different things. For example, what on page 11 is called the "banjo shoulder roast" looks more like what is sold over here as a "picnic shoulder" than the "picnic shoulder roast" next to it. What's shown on page 12 as "Scotch (neck/collar butt)" is sold over here as "Boston butt". It, and our version of the "picnic shoulder", either separately or together as a "full pork shoulder", are prime material for Southern-style pulled-pork barbecue.
