there are not too many float schools left in oz these's day, if your just looking for an float experiance wth you at the controls then maybee go for a flight or two with Steve krug of seawing in sydney, he's qualified to do endo's so if you already have a licence you can fly.
be warned float flying is addictive! we have all the cool landing spots!
