There was a problem during yesterday which resulted in redirects issued to mobile devices being cached and issued to other (desktop) users.
It looks like some of these redirects might still be floating around in caches (proxy servers, browsers etc.).
We'll look at this, but as a short-term workaround, you could try appending some dummy parameter to make the URL unique to get around your browser cache. Like http://www.weatherzone.com.au/qld/capricornia/yeppoon?1
