(1) A relevant authority shall commence the development and implementation of a program on the operative day.
(2) The operative day is:
(a) in relation to an authority that is a relevant authority on 1 July 1987 or such later day as is prescribed--that day or that later day; and
(b) in any other case--the day on which an authority becomes a relevant authority.
(3) A reference in paragraph ( 2)(b) to an authority becoming a relevant authority on a particular day includes a reference to an authority that comes into existence on that day.
(4) Where, at any time, an authority ceases to be a relevant authority because the number of employees employed by it in Australia falls below 40, this Act continues to apply to the authority as if the authority was a relevant authority unless and until the number of employees employed by it in Australia falls below 30.
