Ann: FY19 Financial Results Media Release, page-50

Commsec iress is where I get the data. The shorts being returned is an educated guess based on the volume and code of the trade and total shorts outstanding. That amount of short positions can only be closed efficiently if they find willing big holders to buy back from (there was a UK fund taking some profits before the results.They might be the seller). Still early stages of shorts moving out, imo.

There was another large 368K crossing at 3:50pm.

If its not shorters covering, better still as you have a large buyer. The shorters can cough up at higher prices.

Either way, these are very solid volumes (and increasing). So it looks the real deal.
