Payments Online - More Information
To make using the online payments service even more secure we automatically instruct most browsers to no longer cache personal information (i.e. store information in their memory). We are able to do this in the majority of instances but strongly advise that after you have completed making all your payments that you return to the home page using the link on the final page.
Where the browser does not cache information, you may not be able to retrieve the last page you have visited by using the browser's back button. In some cases you may have to follow additional steps to refresh the page which you have seen. Using the navigation buttons on the online payments service pages avoids any navigation problems.
