One response to the "false depth", as your have been putting it, is to take advantage of a potential opportunity when a seller or buyer wants to trade such a large quantity of shares through the market that could soak up the depth and actually result in a trade at those extreme prices. This may only happen very rarely but we have seen it time and time again where brokers have "fat thumbs".

As soon as you are able to provide a justifiable answer then ASIC can't take it any further.

I am not saying that this is why the orders are there, it just provides an explanation to ASIC in the event of a question.
