Sorry to disapoint, but as I said, if you cut and paste you go to the correct site, ie at westpac.com.au, , so the address shown is a real one within westpacs site, if however you click on it in HTML format, then the browser will be diverted to a site using the http address (ie numbers only), which can then load up and looks exactly as a wbc site. BTW my Hotcopper view of that post is not Html enabled, so the only way of navigating it is with a cut and paste- so I went to the real site- as did anyone else who used cut and paste.
So yes it is a scam, but by using copy and paste, as I had too you do go to the real site, only Yak would be fooled because of the html fast click on the email, for info see http://www.computerworld.com.au/index.php?id=214522091&fp=16&fpid=0 They cannot avoid the numbers coming up when redirecting you - if you are on cable you are gonna have to pay attention though because the number of the site will only flash up for a second.
for info on WBC's policies read http://www.westpac.com.au/internet/publish.nsf/Content/PBOB+types+of+fraud You will notice that the do not say that they dont send emails out - quite the contrary - time they changed their giudelines perhaps.
