I would also like to mention Camera Electronics in Perth http://www.cameraelectronic.com.au/, they are the last second hand dealer of camera stuff in Western Australia. They can be a little pricey but will move on price and have an in house repair shop so you know your in good hands. Some times I find its better to pay that bit extra and rest easy in the comfort of knowing the goods (like my Zorki 4K) will work correctly. Also if you like russian equipment these guys http://www.fedka.com are EXCELLENT!!
