Payroll tax on Super

Ok

So i have set up in my payroll An Expense catagory - Payroll Tax

The Set says - use calculation equals x% of Gross Wages.

In the Payroll tax Information I ahve tciked the relevant catagories for payroll tax and ticked superannuation

When I look Gross Wages is used to calcuation Super and does not include Super as Gross wages is the correct defintion for reportable items to ATO.

However the correct state of victoria compuation is Gross wages plus Superannuation paid to be multipled by the rate.

So my payroll tax computed by MYOB is incorrect. 

How Do I set this up properly so Payroll Tax is correctly computed and accrued and I can generate the right EFT BACS file to lodge. 

Do I crete to Expense catagories for payroll tax one for Gross wages and second one for Super? Help please.
