My worker is saying the rate on the approved timesheet doesn't match their payslip,have they been paid correctly?

The rate on the contractor is usually super inclusive while the rate on the payslip is super exclusive

The approved timesheet report contractors receive shows the full value of the timesheet which will include PAYG tax and superannuation. Payslips will show the breakdown of superannuation and PAYG tax as well as any other deductions they may have. What is left is the net payment or the amount that is processed into their bank account. Any "OTE" (ordinary time earnings) rates displayed on payslip are shown exclusive of superannuation.
