Large low price order: 5 million at 0.5 cents

I saw someone mention this, but was hoping to get some further info.

Apparently out of the 7 million or so on the buy side, there is an order for 5 million at 0.5 cents, the other 51 orders total around 2 million, with the lowest around 6 cents. In my system (commsec) only the top 50 orders are shown, so I can't see that low (ball?) order, but I called people at commsec, the system I use.

Can anyone shed some light on that order? What's its purpose? A catch in case the company goes broke? Window dressing to make it appear there is more demand than there is? Are those sorts of out of the ball park offers common? Whose order is it?

Just interested
