Public holidays vary from state to state, and the employee entitlements for work done on a public holiday also depend on whether the employee is covered by an award, and which award applies.
it's important to be aware of the dates for public holidays, and the entitlements that apply. The following links from the Workplace Ombudsman will be helpful:
- Workplace Ombudsman: 2014 Public Holidays for each State and Territory
- Workplace Ombudsman: Working on public holidays (includes a tool to check whether a particular award applies)
To complicate matters, some states have different holidays for metropolitan and regional areas and you might need to check with the relevant state agency to confirm. In Western Australia, for example, the Queen's Birthday holiday is on 29 September 2014 in Perth and other parts of the state, but some regions observe the holiday on different dates. The WA Department of Commerce has a list of the regional variations here.
