For an employee working in Victoria for a national-system employer, long service leave entitlements are primarily governed by the **State Government of Victoria**. 

While the federal *Fair Work Act 2009* (Cth) includes long service leave as one of the National Employment Standards (NES), the federal legislation does not set a single, uniform national long service leave figure. Instead, the NES explicitly defers to and preserves state and territory long service leave laws (unless an applicable pre-modernized federal award or specific enterprise agreement contains preserved long service leave terms). 

Therefore, in this specific jurisdiction, the employee's long service leave entitlement is worked out under Victorian state law, specifically the ***Long Service Leave Act 2018* (Vic)**.
