Karratha and Port Hedland
Pilbara employers pay payroll tax as Perth employers do, but the King’s Birthday holiday moves to August.
- In the City of Karratha and the Town of Port Hedland, the King’s Birthday is observed on Monday 3 August 2026, instead of the date kept in the rest of Western Australia.
- Monday 28 September 2026 is not a public holiday in those two districts, so a business with staff in Perth and the Pilbara runs two holiday calendars.
- The two districts can choose different dates: in 2024 Karratha observed the holiday on 5 August and Port Hedland on 12 August, so each year’s dates are checked before the pay calendar is set.
