I am searching to find a course anywhere around the Brisbane area, Gold or Sunshine coast would be okay too. I hope that someone will be of help, thank you.
Planet Cake are going to be running some classes out their later in the year, you can register at their site http://www.planetcake.com.au (select courses)
Or contact someone at the Australian National Cake Decorator's Association and ask about branches in QLD, often there are ladies that run classes through their local branch http://www.ancda.org/
look on youtube and get some great films of decorating tips
