Aerosonde are based in Blackburn, Victoria. They did some testing at Hamilton as well as 2 other locations. The company was started by Australian's but was sold to Textron. The Aerosone aeroplane (without meaning to demean it, its a clever thing) is like a big model aeroplane. The current state of UAV's is that they are more the size of FA18's. If you're serious about UAV's you'll need to go overseas and work for one of the major defense contractors.
