Yes am aware that skydivers used to jump out of Barwon Heads Airport but that is a thing of the past I think, no jumpers for about 2 years down that way. Some may still do it at Torqair but am not sure (they never gave any problems or headaches to pilots in the area.)
The jumpers at RJL Aviation at Ceres way do a good job with no hassles that way either (looks as though Tigers of Torquay may be a bit of a problem.)
the last statement is based on your observation?
The powered hang gliders are around as you say but they seem to run a good operation have not heard a bad word about them. (except for your comment)
