Commentary on Sections Part 3: Planning Control. Section 23: Meaning of “development”
This section re-enacts the broad definition of the meaning of development and clarifies what is deemed to be included under the term, “building operations”.  It also lists the operations or uses of land which, for the purposes of the Act, do not involve development of land.  An amendment is included to exclude (for certain buildings specified by direction) structural alteration consisting of partial demolition from the definition of development.
