CommSec shows 126mn volume. Taking it at the average of open and close price, it's approximately $82mn. the next best day (8/11/2021) was approximately $55mn in trades. BY FAR the biggest day in AVZ history. Please correct me if my calculations are significantly wrong.
Also, the average trade size was around 25000 (approx $16000) which is pretty big!
