Look at the Course of Sales below, only one trade could possibly (unlikely given the size and timing) have been placed by a retail investor (second from the top, 116 shares at 1.4650). All the rest are at 1.4725 and are certainly institutional, as no retail investor can buy or sell above $1.00 in quarter cent increments. So instead of having to buy at 1.4750, institutions can buy at 1.4725. Total shares (excluding the 116) are 2,163, times a quarter of a cent is $5.41 of illegal gain if the market is "fair, orderly and transparent". It doesn't matter that $5.41 is peanuts. Peanuts add up, and those peanuts are not available to retail investors. Not blaming the institutional investors for getting the best price, just pissed at the ASX and ASIC for continuing to let this happen under their noses.
