How much to charge client for project files?

Have a client that wants all Premier and AE project files for a job we are doing for them.  They want to take the files and edit in-house should anything need to be changed in the future.  How many out there charge for this?  How much?

add another mark up if your clients are in Australia so $60 becomes $90... just assume people are too dum to notice or care
