Long service leave entitlements for employees of national-system employers under the Fair Work Act 2009 (Cth) are not set by that Act or any other federal law. They are instead governed by the long service leave statute of the state or territory in which the employee works (or, in limited cases, the state or territory with the closest connection to the employment).

No single figure or formula applies uniformly across Australia. Qualifying periods, accrual rates, payment on termination and other conditions differ between jurisdictions, so the applicable entitlement must be determined by reference to the employee’s location.
