2026 Public Holidays on Saturdays for WA

Hi all,

My employer is insisting that we won't be receiving penalty rates for working on the public holidays that fall on a Saturday (Boxing Day and ANZAC Day) because "the official public holidays are the following Monday". However, on The Fair Work Ombudsman website, both the Saturdays and Mondays are listed as holidays, with the Mondays being called "additional public holidays", which to me means they are both holidays.

Can anyone help clear this up? He seems to think the FWO website is written ambiguously.

Thanks!
