From the Act
136 Owners corporation to display and give certain notices
(1) An owners corporation given a copy of an application for an order under this Chapter accompanied by the relevant notice must:
(a) immediately cause the application and notice or a copy of the application and notice to be prominently displayed on any notice board required to be maintained by or under the by-laws on some part of the common property, and
(b) keep the application and notice so displayed until the expiration of the time specified in the notice for the making of submissions,
and
(c) immediately serve a copy of the application and notice on each person whose name appears on its strata roll.
So their dosn’t seem to be a requirement to serve it to ALL owners just those affected by the dispute.
BUT if it affects all owners then I believe it should then be sent to all owners and the OC must bear the cost.
