The employee's long service leave entitlement is governed by **Victorian state law**, specifically the **Long Service Leave Act 2018 (Vic)**.

This is because long service leave is **not** a matter covered by the Fair Work Act 2009 (Cth) or included in the National Employment Standards. Despite the employee working for a national-system employer, long service leave remains a **state and territory responsibility** under Australia's federal system of workplace relations.

The applicable law is determined by the **state or territory in which the employee works**, not by the employer's national-system status. Since this employee works in **Victoria**, Victorian state legislation applies. Each Australian jurisdiction maintains its own separate long service leave legislation with different accrual rates, qualifying periods, and entitlements—there is no uniform national standard.
