Happy to help you with purchasing the kit online and building it yourself, its not difficult. I help our local club run their shop so I have some knowledge on the equipment type and quality. Penders will sell you all the hive materials you need online and are reliable, they are based in NSW. I have also put some information sheets together for my local club as well in the Basic Beekeeping section of this site for building a hive from scratch.
