Dampier Mining Co Ltd v Commissioner of Taxation (Cth) [1981] HCA 29

Expenditure incurred in dredging the outer channel and constructing navigational aids was not deductible, as it did not result in improvements upon the leased land nor was the land used by the lessee for producing assessable income. However, expenditure incurred in dredging the inner harbour and using the spoil for making improvements to the industrial lease land was fully deductible under s. 88(2), with no apportionment required.
