Sections 5A to 11B contain definitions of terms that are used in this Act.
Subsection 5Q(1) contains an entry for each expression that is defined for the purposes of this Act. That subsection is like a Dictionary.
The entry is either an actual definition of the expression or a signpost definition that identifies the provision that defines the expression.
Many other sections in this Part contain the actual definitions relating to a particular topic. For example, sections 6 to 6F deal with operational service and section 5H contains income test definitions.
