Notice of Exercise of Options Form, page-50

Not according to the prospectus:

From section 5.2:

1. (k) Issue of Shares
   For each Option that is exercised, the Company must issue to the Option holder one Share, credited as fully paid and, within 5 Business Days (or such other period as is required by the ASX Listing Rules) after the date of exercise of the Option, issue (or cause to be issued) to the Option holder a Holding Statement or other appropriate evidence of title for each Share that is issued.

I would think the only unknowns here are what exactly is meant by the date of exercise of the Option and also does the ASX listing rules allow a longer period. Technically there is nothing to say that when they receive the money that becomes the day the Option is exercised. Perhaps they can just wait until enough "exercise" requests have been received and then perform an exercise of that amount. Administratively that might be easier, but not what one would expect from the wording above.
