I live on the gold coast which is about 45 minutes drive south of brisbane. There are a few reef catering shops down here. checkout
www.coralplantations.com and
www.gnsaquarium.com.au, These guys are really good, there is another one that i coonsider just about the best called "Aquariums in Paradise" in Ashmore bt he doesnt have a web site, i will find his phone number and post it soon., i go to this store more than any others, but "Coral Plantations" has a huge range of corals that must be seen, check out the website. Hope this helps.
