If you are talking about the "Additional" free options, management have to determine how many they have to issue following the exercise of the Bonus options and then apply to the ASX to be listed.
Note that another 3B registered today, so, I'd reckon that that should be the last one and they now know the final number.
One Additional option will be issued for every one Bonus option that was exercised and probably will be listed on the market and be able to be traded. That's also a bonus. Shouldn't be long now.
