Hi hansen-chris,
Once the employee reaches pre-tax earnings of more than $450, you are required to make Super Guarantee payments on those earnings.
The message in the pay slip is saying that previous pay runs in the month did not amount to more than $450 in earnings, but this most recent pay run pushed the monthly earnings over the $450 threshold, and therefore is including the amount of super from previous pay runs in the month as well.
Hope this explains what the figures represent!
