Dear Australian Communications and Media Authority,
Re: au.gov.aca.cas.numb.util.exception.ApplicationException: Sorry, your browser is not supported.
There is no godly reason why you should have a web site that only supports IE, or at least doesn’t support Firefox. (I’d love to check it in Safari, but the iCapture Safari checker is down at the moment.)
This is particularly stupid since part of your responsibilities include Internet services in Australia. Fix it please.
