We have a known problem when auto-fill is being used to make credit card payments online.
We advise not to use auto-fill when you pay by credit card online.
If you have used auto-fill it can sometimes cause a duplicate payment. If a duplicate payment occurs, the additional amount will be automatically returned to the credit card following the next payment distribution period.
Swimming Australia processes it's payment distribution twice monthly. If there has been an overpayment you should expect to see your payment returned between 7 to 21 days.
