Hi Micheal,
I just stumbled across your post while surfing the net and thought I might respond.
Seeing that you posted this a few months ago you may have already figured out the following for yourself...
To operate a UAV commercially within Australian airspace not only do you need a Controllers Certificate but you also need an Operators Certificate. The CC is a walk in the park compared to the OC! The OC will also cost you several thousand dollars, CASA estimate $7000-$8000 but this depends a lot on the complexity of what you are intending on doing. Insurance is also a big one with most PL annual premiums costing well into the thousands. It is an incredibly daunting and expensive process but I guess if you persevere one would hope that the rewards will be waiting for you at the end. A lot of this information can be found on CASA's website.
I know all of this as I am just about to submit my application for an OC. It has taken me months (and months) of work to get it prepared and I am expecting to get it kicked back by CASA possibly more than once until I finally gain their approval.
I am starting an aerial surveying company utilising UAS as the data capture platform. I am a qualified surveyor with a very keen interest in aviation so once these UAV's started popping up here and there I decided to give it a crack. If I knew back then what I know now, I potentially wouldn't have bothered. It has been a massive undertaking and I have invested close to $100k in the business so far, a business that is currently incapable of making any money!! Hopefully I can gain CASA approval sooner rather than later!
Hopefully this doesn't scare you off but I just think that it is important that people know the full extent of what they may be getting into, as I certainly didn't! If you would like to ask me any questions regarding the whole process, feel free, although a lot of the information and documents I have developed will not be released as they are the backbone of my company. My website is

Good luck, I hope it is all going well so far.
Matt.
