5 Identifiable amounts were to be paid for specific parcels of land over stages. The transferee of the land was also to pay other amounts which were made payable under the Development Agreement. Seven parcels of land were transferred of relevance to these proceedings which may be referred to as Dock 5, Mosaic, C3/C4, C10 (Montage), C9 (Myer), V4 (MKWH) and V5 (Convesso). Each proceeding relates to one of these parcels of land although two proceedings relate to the Dock 5 land. That is because the Dock 5 parcel was reassessed for duty but the earlier assessment was not completely subsumed by the second. The Commissioner has assessed for duty in each case of the seven parcels of land the amount paid for the relevant land as determined by the relevant land sale contract but has also included in the assessment of duty other amounts payable by LLD (that is, by one of the appellants) by reference to the land. The additional amounts included in the Commissioner's assessment, as I have indicated, were generically the same in more than one assessment and (in addition to the amount identified specifically for the land) included amounts payable for what may conveniently be described as External Infrastructure Contribution, Base External Infrastructure Contribution, Gasworks Site Remediation Contribution, Base Gasworks Site Remediation Contribution, Integrated Public Art Contribution, Grand Plaza Retention Amount, Grand Plaza Additional Amount, Grand Plaza Contribution, Additional Land Payment, Final Land Payment, Additional Authority Payment, Estimate of Outstanding Amounts, Estimated Land Payment, Estimated External Infrastructure Contribution, Estimated Gas Site Remediation, Non-monetary Contribution and GST.
