Hey Ewen,
Poor representation is the answer. Whichever kites the retailers tend to push the most, is what will be most prolific on the water.
I don't know who even does Airush in Melbourne. It used to be Four Winds, and RPS. Don't know about now.
It's a pity because Airush kites are solid kites. A DNA is good for beginners because they are a snap to relaunch and have 100% depower by simply letting go of the bar.
@ ex2500, We are selling off our school kites and have a few 6's. If you are keen PM me.
Good winds,
