It does provide information on total land area size, but doesn't tell Land Use. I found that Mesh blocks data set provides information on Land Use.
I have attached csv. file with all the codes which can be used to attach land use information for SA1,2,3,4.
And here is link for mesh blocks digital boundaries, for all states: http://www.abs.gov.au/AUSSTATS/abs@.nsf/DetailsPage/1270.0.55.001July%202016?OpenDocument
Would that be correct to refer to this information?
