i think sheddweller you are underselling severne a little. the prototypes were stitched in WA last time i checked and there is certainly more than one pro getting around with hand made sails by ben in WA. sure the average punter like me can't order custom under normal circumstances but the average punter also doesn't want to pay 2.5k for a sail just because it's made in oz.
KA, Andrew doesn't own ka and hasn't for years. still, designers and testers live in Australia so it's got the connection. like all sail brands they have to compete with price so use overseas factories. i'm not across any commercially available sail brand that doesn't.
Amac does still
own KA sails Australia. But he licences out the Windsurfing side of it. Most of the design, and much of the testing and development is done in Australia.
There are numerous sailmakers who have built, can build, and probably still build the odd prototype or special order windsurfing sails in Australia.
Building a sail is not Rocket Science, and I personally know of at least half a dozen windsurfers who have successfully had a go at making their own sails.

(Advanced design is a LOT more of an art/science!) But the economics of custom or bespoke commercial production locally (and just about probably anywhere else) just don't make much sense anymore, and probably has not since around the late '80's. Production sails are now all made in specialised factories, but many brands still have small design and development lofts in their countries of origin.
Back in the late '80's, a very Talented Kiwi sailor, Chris Torkler, visited us for the Sandy Point Speed Trials and blew us all away with his home made, self designed gear. Sails, boards, boom, fins. About the only bits of he gear he didn't make himself were the mast and the U-Joint, and I recon he could have made a pretty decent mast if he put his mind to it!
