"The option expiry date is not relevant either, as the option can be converted at any time prior to the expiry date."
Not quite right, these are European style options and can't be converted at any time, they can only be converted on the expiry date. That is one reason why they trade at such a discount.
Note: I couldn't find the announcement referred to above by GordonAcko. I searched CommSec, the ASX and the KDR websites and still couldn't find it. All I could find was this reference here on the KDR website:
