Well, if you have a full service broker, I suppose yes......
The process isn't that complex - the supplier of the warrant (e.g. Macquarie) should have a copy of an exercise form in the PDS that came with the warrant - you can get this off
www.asx.com.au.
However, I just wonder why you want to exercise - I mean, in my experience in trading warrants (be that installment or call/put), I want the leverage - normally I close out before expiry, especially if profits are on the table. Otherwise, you can always roll the warrant into a new series. You may wish to discuss these issues with your broker.
Cheers
