Asking for a partner.
They joined this NSW employer as a casual in Oct 2009 and became permanent full time in Sep 2011.
In their long service leave, they have been assigned 264 hours but it appears that minimum LSL in NSW is 325hrs(8.67 weeks).

Did the employer assign incorrect hours or are we calculating incorrectly?
You talk about hours, but your link talks about months and days.
I reckon that's where the difference lies.
Your partner should have lsl equivalent to 2 months or 8.67 weeks.
