Why these guides exist
ASIC and ASX publish important short-selling files, but the raw data is not self-explanatory. A high short-interest number might reflect a consensus bearish view, a hedge, a crowded arbitrage position, or a temporary reporting effect. A falling number might reflect covering, but it can also follow a corporate action or a change in borrow availability.
ShortInterest.au combines data pages with educational context so readers can inspect what changed, understand which source produced each figure, and decide what else needs to be checked before forming a view.
