Long service leave is not governed by one uniform national entitlement under the Fair Work Act 2009 (Cth).

For most employees, including employees of national-system employers, long service leave is mainly governed by the relevant **State or Territory long service leave legislation** (and sometimes an applicable award or enterprise agreement). That means:

- there is **no single Australia-wide figure** that applies the same way everywhere;
- the entitlement, accrual, and timing depend on the **employee’s location / place of work**; and
- you work it out by identifying **which State or Territory law applies** to that employee and then applying that jurisdiction’s long service leave rules.

So the answer is location-specific: the long service leave entitlement is determined by the law of the State or Territory in which the employee is employed, not by one national rule that is identical across Australia.
