How do I setup Worker's Compensation on Payroll App

We currently have workers receiving Workers Compensation payments and are not working. When I migrated across to Payroll App, Workers Comp payments to employers migrated as OTE. My question is shouldn't it be in Leave as the ATO treat Workers Comp as a (W) in STP 2? But we don't accrue Worker's comp Leave per se. So how do I set it up so it doesn't show up as OTE but the ATO can see that the employee is being paid Workers comp?
