A catalogue of what Australia struck, in which every number carries the document it came from, what that document counted, and how precisely it was printed.
Because the existing ones give you a number and no way to check it. Ask four sources how many 1930 pennies were struck and you may get four answers, and none of them will tell you whether the figure counts coins bearing that date or coins struck during that year. Those are different numbers, and conflating them is the commonest error in published coin data.
So every figure here travels with three things: the document, a verbatim quote from it, and a basis saying what was counted. Where sources disagree, both figures are kept and the disagreement is shown.
Every catalogued issue as a grid, with both faces photographed where a museum holds one, and a record of which ones you have that stays in your own browser.
The whole catalogue is one JSON file with a published schema, plus a guide written for agents rather than people.

It will not tell you what a coin is worth. Mintage, metal content and provenance can be stated truthfully from documents. A market price cannot, so this catalogue does not print one. That is the whole trade: less than you wanted, none of it invented.
92 documented varieties and errors, each graded by the kind of source behind it: 10 primary, 54 scholarly, 27 trade, 1 hobbyist. 16 carry a recorded disagreement between sources.
No valuations. A catalogue that starts pricing rarities has stopped reporting facts.
Four statistics mined out of the branch mints' own memoranda, each record carrying the page it was read from.
The Royal Australian Mint publishes its circulating output twice: rounded to millions on its website, exactly by fiscal year in its annual reports. On 14 coins the two do not agree, by more than rounding can explain.
The mints often reported in aggregate: a value of “silver coin”, or “all denominations”, without splitting it. Those records are kept because they are what the source says, and because they are frequently the only figure for a year. They are not filed under a denomination, since they do not belong to one.
