Hi Melanie,
Here at Wollongong we add all costs to the account (less the GST component). From a technical standpoint not all costs may be considered recoverable (i.e legally able to add to the rate payers account), but if it falls into a defence scenario the registrar or the magistrate will normally make an order as to costs that are payable. If that is the case only the costs that the order amount is for should be added.
Happy for you to contact myself direct if you need more information.
Regards,
Dallas
