Hon DAVID PARKER: Well, the member knows the reason for the change, because he's already mentioned the amount of additional revenue that accrues to the Crown if this change is made. Getting the threshold amounts right is a balance between compliance cost and revenue integrity, and that's why the Government settled for $1 million on most asset sales but excepted the position that had been recommended by the select committee, or by submitters to the select committee, that because, in the case of residential property, there are not the same integrity risks, you can have a higher limit of $7.5 million. That's the reason for those different amounts. Without doing this, there is an integrity risk with the vendor doing something for their benefit that doesn't accord with what the purchaser does. We think that the parties should be required through the mechanisms in this bill to agree and, if there is not agreement, there's a mechanism to resolve that dispute.
