No, there is not an extra substitute public holiday on the following Monday for all employees across Australia when Anzac Day falls on a Saturday in 2026. The additional Monday is not a uniform national entitlement that applies everywhere.

Public holidays (including any substitute or additional days) are primarily determined by state and territory legislation. Some jurisdictions declare the following Monday a public holiday if Anzac Day falls on a Saturday; others observe only 25 April itself and do not provide an extra Monday. Consequently the Monday is a public holiday only in particular jurisdictions.

An individual employee’s entitlement turns on:
- the public-holiday laws of the state or territory in which the employee is based for work purposes (the place that determines which days are public holidays under the Fair Work Act 2009 (Cth) National Employment Standards); and
- any more beneficial or different arrangements contained in an applicable modern award, enterprise agreement or contract of employment.

There is no single national substitute Monday that applies to every employee.
