**No.** There is no single national substitute (or additional) public holiday on Monday 27 April 2026 that applies to all employees across Australia when Anzac Day falls on Saturday 25 April 2026.

Public holidays (including any substitute or additional day for Anzac Day) are set by the laws of each state and territory, not by a uniform national rule. Whether Monday is a public holiday therefore depends on the jurisdiction:

- Some jurisdictions provide for an additional/substitute public holiday on the following Monday when Anzac Day falls on a Saturday.
- Others observe Anzac Day only on 25 April itself (even if it is a Saturday) and do **not** declare the Monday a public holiday.

An individual employee’s entitlement is determined by:
- the public-holiday legislation and gazettals of the state or territory in which they work (or that is otherwise applicable);
- any relevant modern award, enterprise agreement, or employment contract (which may pick up the state/territory public holidays or contain their own provisions); and
- whether they are a national-system employee under the Fair Work Act 2009 (Cth), which generally recognises the public holidays declared by the relevant state or territory.

Because the treatment of Anzac Day on a Saturday is not uniform, a payroll officer must check the specific jurisdiction(s) and industrial instrument(s) that apply to the employees in question rather than assuming a nationwide Monday holiday.
