It's worth noting that those tables are almost exactly perfectly useless. Many of those orders are algorithmic and disappear and reappear in a second's notice. Nothing except the top left and right numbers when ASX is open should be considered real at all. I would go so far as to be absolute - none of those numbers is real but the top ones on each side. Even then, on a slow day, assume some of the top numbers aren't real either, and will slip away in digital nano-seconds.

Spec stocks are extremely vulnerable to manipulation, and it's just a brazenly fraudulent tactic that overseers have chosen not to make illegal or impede in any way - likely because they have some skin in the algorithms in question. It's not super hard or painful to push back on; just add one dollar to every placed order regardless of successful execution with no party exempt (I've even heard a $0.01 tax would be enough), but someone clearly has an interest in allowing it to continue.
