Westpac Business v Personal Login

Have you had the experience where the options available to you when you log into Westpac seems to be more limited than you have been told about? For example, as an administrator of a business bank account with Westpac, if you login using Personal Banking, you will find that it seems to let you in. However, administration options will not be there such as adding users to the account etc. At first I thought it was because of my browser incompatibility but actually all I needed to do was login as a business. Hope that helps someone out there.
