Public holiday rules in Australia are set by each state and territory, not by a single national law. When Anzac Day (25 April) falls on a Saturday, the question of a substitute Monday holiday therefore depends on the specific jurisdiction’s legislation. Some jurisdictions provide a substitute Monday for employees generally covered by that state’s public holiday rules; others do not, or they limit the substitute to particular industries or award-covered employees. An individual employee’s entitlement is determined by the jurisdiction in which they perform their work, together with any applicable modern award, enterprise agreement or employment contract that may modify or supplement the statutory position. There is no uniform national substitute Monday that applies to every employee.
