I've provided an excerpt to the relevant paragraphs (239 - 240) below.
Payments for unused long service leave entitlements while still employed 239. An employer may pay long service leave entitlements as a lump sum in lieu of leave to an employee whilst they remain in that same employment.
240. Although unused long service leave paid as a lump sum on termination is specifically excluded from OTE by its definition in subsection 6(1), if a payment for unused long service leave occurs while the employee remains employed, this amount is paid in connection with the employee’s ordinary hours in the same way as any other long service leave payment. Therefore, the payment of unused long service leave entitlements while still employed is included in OTE.
