No idea about the drillers mate.

There are some nieve players here being honest in saying that they needed to dump a significant amount of heads to convert oppies

OR

there are some smart players who said they needed to dump significant heads and spooked some lower selling today and picked up some bargains.

I'm not sure why you would hold OBs and let them expire, any that are sold now are almost certainly going to get converted by whoever buys them and the seller will take some cash for the sale and either reinvest or put the cash in their pockets. Paying tax is good, it means your making money. I hope to pay heaps of tax.

Letting the OBs just expire would be a crazy decision.
