I'm not sure, but you can rule out about 90% of shareholders.
It appears to be a sell order for 100,000 shares that then hit 5 different buyers. Most of the trade was at 12c but 24.4k was then at 11.5c and the final (if it is final) 840 shares at 11c. From the last AR there were around 100 shareholders in that 100k plus holding size. Someone reduced or sold and they will have their reasons.
Buyers are obviously being cautious in returning the price to see if they have more that they are dumping.
