Not "we could not find any." We looked, and the shelf is empty. Here is the evidence, so you can decide whether that is an opportunity or a warning.
The central bank policy rate is 4.35% (Cash rate target). source
AUD, genuinely empty for on-chain yield. Checked ANZ A$DC, Novatti AUDD, Macropod AUDM (the licensed one, Betashares-backed), Monochrome, Zerocap, Project Acacia's final report, and searched specifically for tokenised AUD money market funds and government bonds. Australia has three or four AUD stablecoins and a completed central-bank research programme, and zero commercially available AUD-denominated on-chain yield instruments. Project Acacia's next-step list includes 'exploring government-issued tokenised bonds', i.e. still ahead, not behind.
An empty shelf in a currency with a real policy rate is a gap between what savers are owed and what they can reach. It closes when someone with the licence to hold the underlying paper is willing to put a claim on it on-chain. Until then, holders of AUD choosing to earn are choosing to hold a different currency, whether they have priced that decision or not. The calculator prices it.
